Retire Packaging Deb project repos
This commit is part of a series to retire the Packaging Deb project. Step 2 is to remove all content from the project repos, replacing it with a README notification where to find ongoing work, and how to recover the repo if needed at some future point (as in https://docs.openstack.org/infra/manual/drivers.html#retiring-a-project). Change-Id: I36400d5ff47dc7ab7f90fd0648ef8684ddbbd724

||||
and distribution as defined by Sections 1 through 9 of this document.
|

||||
the copyright owner that is granting the License.
|
||||
|
||||
"Legal Entity" shall mean the union of the acting entity and all

other entities that control, are controlled by, or are under common
|
||||
control with that entity. For the purposes of this definition,

|
||||
direction or management of such entity, whether by contract or
|
||||
otherwise, or (ii) ownership of fifty percent (50%) or more of the
|
||||
outstanding shares, or (iii) beneficial ownership of such entity.
|
||||
|
||||
"You" (or "Your") shall mean an individual or Legal Entity
|
||||
exercising permissions granted by this License.
|
||||
|
||||
"Source" form shall mean the preferred form for making modifications,
|
||||
including but not limited to software source code, documentation
|
||||
source, and configuration files.
|
||||
|
||||
"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but
|
||||
not limited to compiled object code, generated documentation,
|
||||
and conversions to other media types.
|
||||
|
||||
"Work" shall mean the work of authorship, whether in Source or
|
||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the
|
||||
Licensor for the purpose of discussing and improving the Work, but
|
||||
excluding communication that is conspicuously marked or otherwise
|
||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.

Configuring Watcher
|
||||
===================
|
||||
|
||||
This document is continually updated and reflects the latest
|
||||
available code of the Watcher service.
|
||||
|
||||
Service overview
|
||||
================
|
||||
|
||||
The Watcher system is a collection of services that provides support to
|
||||
optimize your IAAS platform. The Watcher service may, depending upon
|
||||
configuration, interact with several other OpenStack services. This includes:
|
||||
|
||||
- the OpenStack Identity service (`keystone`_) for request authentication and
|
||||
to locate other OpenStack services
|
||||
- the OpenStack Telemetry service (`ceilometer`_) for consuming the resources
|
||||
metrics
|
||||
- the OpenStack Compute service (`nova`_) works with the Watcher service and
|
||||
acts as a user-facing API for instance migration.
|
||||
|
||||
The Watcher service includes the following components:
|
||||
|
||||
- ``watcher-decision-engine``: runs audit on part of your IAAS and return an
|
||||
action plan in order to optimize resource placement.
|
||||
- ``watcher-api``: A RESTful API that processes application requests by sending
|
||||
them to the watcher-decision-engine over RPC.
|
||||
- ``watcher-applier``: applies the action plan.
|
||||
- `python-watcherclient`_: A command-line interface (CLI) for interacting with
|
||||
the Watcher service.
|
||||
- `watcher-dashboard`_: An Horizon plugin for interacting with the Watcher
|
||||
service.
|
||||
|
||||
Additionally, the Watcher service has certain external dependencies, which
|
||||
are very similar to other OpenStack services:
|
||||
|
||||
- A database to store audit and action plan information and state. You can set
|
||||
the database back-end type and location.
|
||||
- A queue. A central hub for passing messages, such as `RabbitMQ`_.
|
||||
|
||||
Optionally, one may wish to utilize the following associated projects for
|
||||
additional functionality:
|
||||
|
||||
- `watcher metering`_: an alternative to collect and push metrics to the
|
||||
Telemetry service.

Install and configure prerequisites
|
||||
===================================
|
||||
|
||||
You can configure Watcher services to run on separate nodes or the same node.
|
||||
In this guide, the components run on one node, typically the Controller node.
|
||||
|
||||
This section shows you how to install and configure the services.
|
||||
|
||||
It assumes that the Identity, Image, Compute, and Networking services
|
||||
have already been set up.
|
||||
|
||||
.. _identity-service_configuration:
|
||||
|
||||
Configure the Identity service for the Watcher service
|
||||
------------------------------------------------------
|
||||
|
||||
#. Create the Watcher service user (eg ``watcher``). The service uses this to
|
||||
authenticate with the Identity Service. Use the
|
||||
``KEYSTONE_SERVICE_PROJECT_NAME`` project (named ``service`` by default in
|
||||
devstack) and give the user the ``admin`` role:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ keystone user-create --name=watcher --pass=WATCHER_PASSWORD \
|
||||
--email=watcher@example.com \
|
||||
--tenant=KEYSTONE_SERVICE_PROJECT_NAME
|
||||
$ keystone user-role-add --user=watcher \
|
||||
--tenant=KEYSTONE_SERVICE_PROJECT_NAME --role=admin
|
||||
|
||||
or (by using python-openstackclient 1.8.0+)
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ openstack user create --password WATCHER_PASSWORD --enable \
|
||||
--email watcher@example.com watcher \
|
||||
--project=KEYSTONE_SERVICE_PROJECT_NAME
|
||||
$ openstack role add --project KEYSTONE_SERVICE_PROJECT_NAME \
|
||||
--user watcher admin
|
||||
|
||||
|
||||
#. You must register the Watcher Service with the Identity Service so that
|
||||
other OpenStack services can locate it. To register the service:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ keystone service-create --name=watcher --type=infra-optim \
|
||||
--description="Infrastructure Optimization service"
|
||||
|
||||
or (by using python-openstackclient 1.8.0+)
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ openstack service create --name watcher infra-optim \
|
||||
--description="Infrastructure Optimization service"
|
||||
|
||||
#. Create the endpoints by replacing YOUR_REGION and
|
||||
``WATCHER_API_[PUBLIC|ADMIN|INTERNAL]_IP`` with your region and your
|
||||
Watcher Service's API node IP addresses (or FQDN):
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ keystone endpoint-create \
|
||||
--service-id=the_service_id_above \
|
||||
--publicurl=http://WATCHER_API_PUBLIC_IP:9322 \
|
||||
--internalurl=http://WATCHER_API_INTERNAL_IP:9322 \
|
||||
--adminurl=http://WATCHER_API_ADMIN_IP:9322
|
||||
|
||||
or (by using python-openstackclient 1.8.0+)
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ openstack endpoint create --region YOUR_REGION watcher \
|
||||
--publicurl http://WATCHER_API_PUBLIC_IP:9322 \
|
||||
--internalurl http://WATCHER_API_INTERNAL_IP:9322 \
|
||||
--adminurl http://WATCHER_API_ADMIN_IP:9322
|
||||
|
||||
.. _watcher-db_configuration:
|
||||
|
||||
Set up the database for Watcher
|
||||
-------------------------------
|
||||
|
||||
The Watcher service stores information in a database. This guide uses the
|
||||
MySQL database that is used by other OpenStack services.
|
||||
|
||||
#. In MySQL, create a ``watcher`` database that is accessible by the
|
||||
``watcher`` user. Replace WATCHER_DBPASSWORD
|
||||
with the actual password::
|
||||
|
||||
$ mysql -u root -p
|
||||
|
||||
mysql> CREATE DATABASE watcher CHARACTER SET utf8;
|
||||
mysql> GRANT ALL PRIVILEGES ON watcher.* TO 'watcher'@'localhost' \
|
||||
IDENTIFIED BY 'WATCHER_DBPASSWORD';
|
||||
mysql> GRANT ALL PRIVILEGES ON watcher.* TO 'watcher'@'%' \
|
||||
IDENTIFIED BY 'WATCHER_DBPASSWORD';
|
||||
|
||||
|
||||
Configure the Watcher service
|
||||
=============================
|
||||
|
||||
The Watcher service is configured via its configuration file. This file
|
||||
is typically located at ``/etc/watcher/watcher.conf``.
|
||||
|
||||
You can easily generate and update a sample configuration file
|
||||
named :ref:`watcher.conf.sample <watcher_sample_configuration_files>` by using
|
||||
these following commands::
|
||||
|
||||
$ git clone git://git.openstack.org/openstack/watcher
|
||||
$ cd watcher/
|
||||
$ tox -e genconfig
|
||||
$ vi etc/watcher/watcher.conf.sample
|
||||
|
||||
|
||||
The configuration file is organized into the following sections:
|
||||
|
||||
* ``[DEFAULT]`` - General configuration
|
||||
* ``[api]`` - API server configuration
|
||||
* ``[database]`` - SQL driver configuration
|
||||
* ``[keystone_authtoken]`` - Keystone Authentication plugin configuration
|
||||
* ``[watcher_clients_auth]`` - Keystone auth configuration for clients
|
||||
* ``[watcher_applier]`` - Watcher Applier module configuration
|
||||
* ``[watcher_decision_engine]`` - Watcher Decision Engine module configuration
|
||||
* ``[oslo_messaging_rabbit]`` - Oslo Messaging RabbitMQ driver configuration
|
||||
* ``[ceilometer_client]`` - Ceilometer client configuration
|
||||
* ``[cinder_client]`` - Cinder client configuration
|
||||
* ``[glance_client]`` - Glance client configuration
|
||||
* ``[nova_client]`` - Nova client configuration
|
||||
* ``[neutron_client]`` - Neutron client configuration
|
||||
|
||||
The Watcher configuration file is expected to be named
|
||||
``watcher.conf``. When starting Watcher, you can specify a different
|
||||
configuration file to use with ``--config-file``. If you do **not** specify a
|
||||
configuration file, Watcher will look in the following directories for a
|
||||
configuration file, in order:
|
||||
|
||||
* ``~/.watcher/``
|
||||
* ``~/``
|
||||
* ``/etc/watcher/``
|
||||
* ``/etc/``
|
||||
|
||||
|
||||
Although some configuration options are mentioned here, it is recommended that
|
||||
you review all the `available options
|
||||
<https://git.openstack.org/cgit/openstack/watcher/tree/etc/watcher/watcher.conf.sample>`_
|
||||
so that the watcher service is configured for your needs.
|
||||
|
||||
#. The Watcher Service stores information in a database. This guide uses the
|
||||
MySQL database that is used by other OpenStack services.
|
||||
|
||||
Configure the location of the database via the ``connection`` option. In the
|
||||
following, replace WATCHER_DBPASSWORD with the password of your ``watcher``
|
||||
user, and replace DB_IP with the IP address where the DB server is located::
|
||||
|
||||
[database]
|
||||
...
|
||||
|
||||
# The SQLAlchemy connection string used to connect to the
|
||||
# database (string value)
|
||||
#connection=<None>
|
||||
connection = mysql://watcher:WATCHER_DBPASSWORD@DB_IP/watcher?charset=utf8
|
||||
|
||||
#. Configure the Watcher Service to use the RabbitMQ message broker by
|
||||
setting one or more of these options. Replace RABBIT_HOST with the
|
||||
IP address of the RabbitMQ server, RABBITMQ_USER and RABBITMQ_PASSWORD
|
||||
by the RabbitMQ server login credentials ::
|
||||
|
||||
[DEFAULT]
|
||||
|
||||
# The messaging driver to use, defaults to rabbit. Other drivers
|
||||
# include qpid and zmq. (string value)
|
||||
#rpc_backend = rabbit
|
||||
|
||||
# The default exchange under which topics are scoped. May be
|
||||
# overridden by an exchange name specified in the transport_url
|
||||
# option. (string value)
|
||||
control_exchange = watcher
|
||||
|
||||
...
|
||||
|
||||
[oslo_messaging_rabbit]
|
||||
|
||||
# The username used by the message broker (string value)
|
||||
rabbit_userid = RABBITMQ_USER
|
||||
|
||||
# The password of user used by the message broker (string value)
|
||||
rabbit_password = RABBITMQ_PASSWORD
|
||||
|
||||
# The host where the message brokeris installed (string value)
|
||||
rabbit_host = RABBIT_HOST
|
||||
|
||||
# The port used bythe message broker (string value)
|
||||
#rabbit_port = 5672
|
||||
|
||||
|
||||
#. Watcher API shall validate the token provided by every incoming request,
|
||||
via keystonemiddleware, which requires the Watcher service to be configured
|
||||
with the right credentials for the Identity service.
|
||||
|
||||
In the configuration section here below:
|
||||
|
||||
* replace IDENTITY_IP with the IP of the Identity server
|
||||
* replace WATCHER_PASSWORD with the password you chose for the ``watcher``
|
||||
user
|
||||
* replace KEYSTONE_SERVICE_PROJECT_NAME with the name of project created
|
||||
for OpenStack services (e.g. ``service``) ::
|
||||
|
||||
[keystone_authtoken]
|
||||
|
||||
# Authentication type to load (unknown value)
|

|
||||
project_name = KEYSTONE_SERVICE_PROJECT_NAME
|
||||
|
||||
#. Watcher's decision engine and applier interact with other OpenStack
|
||||
projects through those projects' clients. In order to instantiate these
|
||||
clients, Watcher needs to request a new session from the Identity service
|
||||
using the right credentials.
|
||||
|
||||
In the configuration section here below:
|
||||
|
||||
* replace IDENTITY_IP with the IP of the Identity server
|
||||
* replace WATCHER_PASSWORD with the password you chose for the ``watcher``
|
||||
user
|
||||
* replace KEYSTONE_SERVICE_PROJECT_NAME with the name of project created
|
||||
for OpenStack services (e.g. ``service``) ::
|
||||
|
||||
[watcher_clients_auth]
|
||||
|
||||
# Authentication type to load (unknown value)
|
||||
# Deprecated group/name - [DEFAULT]/auth_plugin

|
||||
#project_name = <None>
|
||||
project_name = KEYSTONE_SERVICE_PROJECT_NAME
|
||||
|
||||
#. Configure the clients to use a specific version if desired. For example, to
|
||||
configure Watcher to use a Nova client with version 2.1, use::
|
||||
|
||||
[nova_client]
|
||||
|
||||
# Version of Nova API to use in novaclient. (string value)
|
||||
#api_version = 2
|
||||
api_version = 2.1
|
||||
|
||||
#. Create the Watcher Service database tables::
|
||||
|
||||
$ watcher-db-manage --config-file /etc/watcher/watcher.conf create_schema
|
||||
|
||||
#. Start the Watcher Service::
|
||||
|
||||
$ watcher-api && watcher-decision-engine && watcher-applier
|
||||
|
||||
Configure Nova compute
|
||||
======================
|
||||
|
||||
Please check your hypervisor configuration to correctly handle
|
||||
`instance migration`_.
|
||||
|
||||
.. _`instance migration`: http://docs.openstack.org/admin-guide/compute-live-migration-usage.html
|
||||
|
||||
Configure Measurements
|
||||
======================
|
||||
|
||||
You can configure and install Ceilometer by following the documentation below :
|
||||
|
||||
#. http://docs.openstack.org/developer/ceilometer
|
||||
#. http://docs.openstack.org/kilo/install-guide/install/apt/content/ceilometer-nova.html
|
||||
|
||||
The built-in strategy 'basic_consolidation' provided by watcher requires
|
||||
"**compute.node.cpu.percent**" and "**cpu_util**" measurements to be collected
|
||||
by Ceilometer.
|
||||
The measurements available depend on the hypervisors that OpenStack manages on
|
||||
the specific implementation.
|
||||
You can find the measurements available per hypervisor and OpenStack release on
|
||||
the OpenStack site.
|
||||
You can use 'ceilometer meter-list' to list the available meters.
|
||||
|
||||
For more information:
|
||||
http://docs.openstack.org/developer/ceilometer/measurements.html
|
||||
|
||||
Ceilometer is designed to collect measurements from OpenStack services and from
|
||||
other external components. If you would like to add new meters to the currently
|
||||
existing ones, you need to follow the documentation below:
|
||||
|
||||
#. http://docs.openstack.org/developer/ceilometer/new_meters.html
|
||||
|
||||
The Ceilometer collector uses a pluggable storage system, meaning that you can
|
||||
pick any database system you prefer.
|
||||
The original implementation has been based on MongoDB but you can create your
|
||||
own storage driver using whatever technology you want.
|
||||

|
||||
|
||||
|
||||
Configure Nova Notifications
|
||||
============================
|
||||
|
||||
Watcher can consume notifications generated by the Nova services, in order to
|
||||
build or update, in real time, its cluster data model related to computing
|
||||
resources.
|
||||
|
||||
Nova publishes, by default, notifications on ``notifications`` AMQP queue
|
||||
(configurable) and ``versioned_notifications`` AMQP queue (not
|
||||
configurable). ``notifications`` queue is mainly used by ceilometer, so we can
|
||||
not use it. And some events, related to nova-compute service state, are only
|
||||
sent into the ``versioned_notifications`` queue.
|
||||
|
||||
By default, Watcher listens to AMQP queues named ``watcher_notifications``
|
||||
and ``versioned_notifications``. So you have to update the Nova
|
||||
configuration file on controller and compute nodes, in order
|
||||
to Watcher receives Nova notifications in ``watcher_notifications`` as well.
|
||||
|
||||
* In the file ``/etc/nova/nova.conf``, update the section
|
||||
``[oslo_messaging_notifications]``, by redefining the list of topics
|
||||
into which Nova services will publish events ::
|
||||
|
||||
[oslo_messaging_notifications]
|
||||
driver = messagingv2
|
||||
topics = notifications,watcher_notifications
|
||||
|
||||
* Restart the Nova services.
|
||||
|
||||
|
||||
Workers
|
||||
=======
|
||||
|
||||
You can define a number of workers for the Decision Engine and the Applier.
|
||||
|
||||
If you want to create and run more audits simultaneously, you have to raise
|
||||
the number of workers used by the Decision Engine::
|
||||
|
||||
[watcher_decision_engine]
|
||||
|
||||
...
|
||||
|
||||
# The maximum number of threads that can be used to execute strategies
|
||||
# (integer value)
|
||||
#max_workers = 2
|
||||
|
||||
|
||||
If you want to execute simultaneously more recommended action plans, you
|
||||
have to raise the number of workers used by the Applier::
|
||||
|
||||
[watcher_applier]
|
||||
|
||||
...
|
||||
|
||||
# Number of workers for applier, default value is 1. (integer value)
|
||||
# Minimum value: 1
|
||||
#workers = 1

Guru Meditation Reports
|
||||
=======================
|
||||
|
||||
Watcher contains a mechanism whereby developers and system administrators can
|
||||
generate a report about the state of a running Watcher service. This report
|
||||
is called a *Guru Meditation Report* (*GMR* for short).
|
||||
|
||||
Generating a GMR
|
||||
================
|
||||
|
||||
A *GMR* can be generated by sending the *USR2* signal to any Watcher process
|
||||
with support (see below). The *GMR* will then be outputted as standard error
|
||||
for that particular process.
|
||||
|
||||
For example, suppose that ``watcher-api`` has process id ``8675``, and was run
|
||||
with ``2>/var/log/watcher/watcher-api-err.log``. Then, ``kill -USR2 8675``
|
||||
will trigger the Guru Meditation report to be printed to
|
||||
``/var/log/watcher/watcher-api-err.log``.
|
||||
|
||||
Structure of a GMR
|
||||
==================
|
||||
|
||||
The *GMR* is designed to be extensible; any particular service may add its
|
||||
own sections. However, the base *GMR* consists of several sections:
|
||||
|
||||
Package
|
||||
Shows information about the package to which this process belongs, including
|
||||
version informations.
|
||||
|
||||
Threads
|
||||
Shows stack traces and thread ids for each of the threads within this
|
||||
process.
|
||||
|
||||
Green Threads
|
||||
Shows stack traces for each of the green threads within this process (green
|
||||
threads don't have thread ids).
|
||||
|
||||
Configuration
|
||||
Lists all the configuration options currently accessible via the CONF object
|
||||
for the current process.
|
||||
|
||||
Plugins
|
||||
Lists all the plugins currently accessible by the Watcher service.

Policies
|
||||
========
|
||||
|
||||
Watcher's public API calls may be restricted to certain sets of users using a
|
||||
policy configuration file. This document explains exactly how policies are
|
||||
configured and what they apply to.
|
||||
|
||||
A policy is composed of a set of rules that are used in determining if a
|
||||
particular action may be performed by the authorized tenant.
|
||||
|
||||
Constructing a Policy Configuration File
|
||||
----------------------------------------
|
||||
|
||||
A policy configuration file is a simply JSON object that contain sets of
|
||||
rules. Each top-level key is the name of a rule. Each rule
|
||||
is a string that describes an action that may be performed in the Watcher API.
|
||||
|
||||
The actions that may have a rule enforced on them are:
|
||||
|
||||
* ``strategy:get_all``, ``strategy:detail`` - List available strategies
|
||||
|
||||
* ``GET /v1/strategies``
|
||||
* ``GET /v1/strategies/detail``
|
||||
|
||||
* ``strategy:get`` - Retrieve a specific strategy entity
|
||||
|
||||
* ``GET /v1/strategies/<STRATEGY_UUID>``
|
||||
* ``GET /v1/strategies/<STRATEGY_NAME>``
|
||||
|
||||
|
||||
* ``goal:get_all``, ``goal:detail`` - List available goals
|
||||
|
||||

To limit an action to a particular role or roles, you list the roles like so ::
|
||||
|
||||
{
|
||||
"audit:create": ["role:admin", "role:superuser"]
|
||||
}
|
||||
|
||||
The above would add a rule that only allowed users that had roles of either
|
||||
"admin" or "superuser" to launch an audit.

Ways to install Watcher
|
||||
=======================
|
||||
|
||||
This document describes some ways to install Watcher in order to use it.
|
||||
If you are intending to develop on or with Watcher,
|
||||
please read :doc:`../dev/environment`.
|
||||
|
||||
Prerequisites
|
||||
-------------
|
||||
|
||||
The source install instructions specifically avoid using platform specific
|
||||
packages, instead using the source for the code and the Python Package Index
|
||||
(PyPi_).
|
||||
|
||||
.. _PyPi: https://pypi.python.org/pypi
|
||||
|
||||
It's expected that your system already has python2.7_, latest version of pip_,
|
||||
and git_ available.
|
||||
|
||||
.. _python2.7: https://www.python.org
|
||||
.. _pip: https://pip.pypa.io/en/latest/installing/
|
||||
.. _git: https://git-scm.com/
|
||||
|
||||
Your system shall also have some additional system libraries:
|
||||
|
||||
On Ubuntu (tested on 14.04LTS):
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ sudo apt-get install python-dev libssl-dev libmysqlclient-dev libffi-dev
|
||||
|
||||
On Fedora-based distributions e.g., Fedora/RHEL/CentOS/Scientific Linux
|
||||
(tested on CentOS 7.1):
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ sudo yum install gcc python-devel openssl-devel libffi-devel mysql-devel
|
||||
|
||||
|
||||
Installing from Source
|
||||
----------------------
|
||||
|
||||
Clone the Watcher repository:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ git clone https://git.openstack.org/openstack/watcher.git
|
||||
$ cd watcher
|
||||
|
||||
Install the Watcher modules:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
# python setup.py install
|
||||
|
||||
The following commands should be available on the command-line path:
|
||||
|
||||
* ``watcher-api`` the Watcher Web service used to handle RESTful requests
|
||||
* ``watcher-decision-engine`` the Watcher Decision Engine used to build action
|
||||
plans, according to optimization goals to achieve.
|
||||
* ``watcher-applier`` the Watcher Applier module, used to apply action plan
|
||||
* ``watcher-db-manage`` used to bootstrap Watcher data
|
||||
|
||||
You will find sample configuration files in ``etc/watcher``:
|
||||
|
||||
* ``watcher.conf.sample``
|
||||
|
||||
Install the Watcher modules dependencies:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
# pip install -r requirements.txt
|
||||
|
||||
From here, refer to :doc:`configuration` to declare Watcher as a new service
|
||||
into Keystone and to configure its different modules. Once configured, you
|
||||
should be able to run the Watcher services by issuing these commands:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ watcher-api
|
||||
$ watcher-decision-engine
|
||||
$ watcher-applier
|
||||
|
||||
By default, this will show logging on the console from which it was started.
|
||||
Once started, you can use the `Watcher Client`_ to play with Watcher service.
|
||||
|
||||
.. _`Watcher Client`: https://git.openstack.org/cgit/openstack/python-watcherclient
|
||||
|
||||
Installing from packages: PyPI
|
||||
--------------------------------
|
||||
|
||||
Watcher package is available on PyPI repository. To install Watcher on your
|
||||
system:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ sudo pip install python-watcher
|
||||
|
||||
The Watcher services along with its dependencies should then be automatically
|
||||
installed on your system.
|
||||
|
||||
Once installed, you still need to declare Watcher as a new service into
|
||||
Keystone and to configure its different modules, which you can find described
|
||||
in :doc:`configuration`.
|
||||
|
||||
|
||||
Installing from packages: Debian (experimental)
|
||||
-----------------------------------------------
|
||||
|
||||
Experimental Debian packages are available on `Debian repositories`_. The best
|
||||
way to use them is to install them into a Docker_ container.
|
||||
|
||||
Here is single Dockerfile snippet you can use to run your Docker container:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
FROM debian:experimental
|
||||
MAINTAINER David TARDIVEL <david.tardivel@b-com.com>
|
||||
|
||||
RUN apt-get update
|
||||
RUN apt-get dist-upgrade -y
|
||||
RUN apt-get install -y vim net-tools
|
||||
RUN apt-get install -yt experimental watcher-api
|
||||
|
||||
CMD ["/usr/bin/watcher-api"]
|
||||
|
||||
Build your container from this Dockerfile:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ docker build -t watcher/api .
|
||||
|
||||
To run your container, execute this command:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ docker run -d -p 9322:9322 watcher/api
|
||||
|
||||
Check in your logs Watcher API is started
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ docker logs <container ID>
|
||||
|
||||
You can run similar container with Watcher Decision Engine (package
|
||||
``watcher-decision-engine``) and with the Watcher Applier (package
|
||||
``watcher-applier``).

Components
|
||||
==========
|
||||
|
||||
.. _amqp_bus_definition:
|
||||
|
||||
AMQP Bus
|
||||
--------
|
||||
|
||||
The AMQP message bus handles internal asynchronous communications between the
|
||||
different Watcher components.
|
||||
|
||||
.. _cluster_datasource_definition:
|
||||
|
||||
Datasource
|
||||
----------
|
||||
|
||||
This component stores the metrics related to the cluster.
|
||||
|
||||
It can potentially rely on any appropriate storage system (InfluxDB, OpenTSDB,
|
||||
MongoDB,...) but will probably be more performant when using
|
||||
`Time Series Databases <https://en.wikipedia.org/wiki/Time_series_database>`_
|
||||
which are optimized for handling time series data, which are arrays of numbers
|
||||
indexed by time (a datetime or a datetime range).
|
||||
|
||||
.. _archi_watcher_api_definition:
|
||||
|
||||
Watcher API
|
||||
-----------
|
||||
|
||||
This component implements the REST API provided by the Watcher system to the
|
||||
external world.
|
||||
|
||||
It enables the :ref:`Administrator <administrator_definition>` of a
|
||||
:ref:`Cluster <cluster_definition>` to control and monitor the Watcher system
|
||||
via any interaction mechanism connected to this API:
|
||||
|
||||
- :ref:`CLI <archi_watcher_cli_definition>`
|
||||
- Horizon plugin
|
||||
- Python SDK
|
||||
|
||||
You can also read the detailed description of `Watcher API`_.
|
||||
|
||||
.. _archi_watcher_applier_definition:
|
||||
|
||||
Watcher Applier
|
||||
---------------
|
||||
|
||||
This component is in charge of executing the
|
||||
:ref:`Action Plan <action_plan_definition>` built by the
|
||||
:ref:`Watcher Decision Engine <watcher_decision_engine_definition>`.
|
||||
|
||||
It connects to the :ref:`message bus <amqp_bus_definition>` and launches the
|
||||
:ref:`Action Plan <action_plan_definition>` whenever a triggering message is
|
||||
received on a dedicated AMQP queue.
|
||||
|
||||
The triggering message contains the Action Plan UUID.
|
||||
|
||||
It then gets the detailed information about the
|
||||
:ref:`Action Plan <action_plan_definition>` from the
|
||||
:ref:`Watcher Database <watcher_database_definition>` which contains the list
|
||||
of :ref:`Actions <action_definition>` to launch.
|
||||
|
||||
It then loops on each :ref:`Action <action_definition>`, gets the associated
|
||||
class and calls the execute() method of this class.
|
||||
Most of the time, this method will first request a token to the Keystone API
|
||||
and if it is allowed, sends a request to the REST API of the OpenStack service
|
||||
which handles this kind of :ref:`atomic Action <action_definition>`.
|
||||
|
||||
Note that as soon as :ref:`Watcher Applier <watcher_applier_definition>` starts
|
||||
handling a given :ref:`Action <action_definition>` from the list, a
|
||||
notification message is sent on the :ref:`message bus <amqp_bus_definition>`
|
||||
indicating that the state of the action has changed to **ONGOING**.
|
||||
|
||||
If the :ref:`Action <action_definition>` is successful,
|
||||
the :ref:`Watcher Applier <watcher_applier_definition>` sends a notification
|
||||
message on :ref:`the bus <amqp_bus_definition>` informing the other components
|
||||
of this.
|
||||
|
||||
|
||||
If the :ref:`Action <action_definition>` fails, the
|
||||
:ref:`Watcher Applier <watcher_applier_definition>` tries to rollback to the
|
||||
previous state of the :ref:`Managed resource <managed_resource_definition>`
|
||||
(i.e. before the command was sent to the underlying OpenStack service).
|
||||
|
||||
.. _archi_watcher_cli_definition:
|
||||
|
||||
Watcher CLI
|
||||
-----------
|
||||
|
||||
The watcher command-line interface (CLI) can be used to interact with the
|
||||
Watcher system in order to control it or to know its current status.
|
||||
|
||||
Please, read `the detailed documentation about Watcher CLI
|
||||
<https://factory.b-com.com/www/watcher/doc/python-watcherclient/>`_.
|
||||
|
||||
.. _archi_watcher_dashboard_definition:
|
||||
|
||||
Watcher Dashboard
|
||||
-----------------
|
||||
|
||||
The Watcher Dashboard can be used to interact with the Watcher system through
|
||||
Horizon in order to control it or to know its current status.
|
||||
|
||||
Please, read `the detailed documentation about Watcher Dashboard
|
||||
<http://docs.openstack.org/developer/watcher-dashboard/>`_.
|
||||
|
||||
.. _archi_watcher_database_definition:
|
||||
|
||||
Watcher Database
|
||||
----------------
|
||||
|
||||
This database stores all the Watcher domain objects which can be requested
|
||||
by the :ref:`Watcher API <archi_watcher_api_definition>` or the
|
||||
:ref:`Watcher CLI <archi_watcher_cli_definition>`:
|
||||
|
||||
- :ref:`Goals <goal_definition>`
|
||||
- :ref:`Strategies <strategy_definition>`
|
||||
- :ref:`Audit templates <audit_template_definition>`
|
||||
- :ref:`Audits <audit_definition>`
|
||||
- :ref:`Action plans <action_plan_definition>`
|
||||
- :ref:`Efficacy indicators <efficacy_indicator_definition>` via the Action
|
||||
Plan API.
|
||||
- :ref:`Actions <action_definition>`
|
||||
|
||||
The Watcher domain being here "*optimization of some resources provided by an
|
||||
OpenStack system*".
|
||||
|
||||
.. _archi_watcher_decision_engine_definition:
|
||||
|
||||
Watcher Decision Engine
|
||||
-----------------------
|
||||
|
||||
This component is responsible for computing a set of potential optimization
|
||||
:ref:`Actions <action_definition>` in order to fulfill
|
||||
the :ref:`Goal <goal_definition>` of an :ref:`Audit <audit_definition>`.
|
||||
|
||||
It first reads the parameters of the :ref:`Audit <audit_definition>` to know
|
||||
the :ref:`Goal <goal_definition>` to achieve.
|
||||
|
||||
Unless specified, it then selects the most appropriate :ref:`strategy
|
||||
<strategy_definition>` from the list of available strategies achieving this
|
||||
goal.
|
||||
|
||||
The :ref:`Strategy <strategy_definition>` is then dynamically loaded (via
|
||||
`stevedore <http://docs.openstack.org/developer/stevedore/>`_). The
|
||||
:ref:`Watcher Decision Engine <watcher_decision_engine_definition>` executes
|
||||
the strategy.
|
||||
|
||||
In order to compute the potential :ref:`Solution <solution_definition>` for the
|
||||
Audit, the :ref:`Strategy <strategy_definition>` relies on different sets of
|
||||
data:
|
||||
|
||||
- :ref:`Cluster data models <cluster_data_model_definition>` that are
|
||||
periodically synchronized through pluggable cluster data model collectors.
|
||||
These models contain the current state of various
|
||||
:ref:`Managed resources <managed_resource_definition>` (e.g., the data stored
|
||||
in the Nova database). These models gives a strategy the ability to reason on
|
||||
the current state of a given :ref:`cluster <cluster_definition>`.
|
||||
- The data stored in the :ref:`Cluster Datasource
|
||||
<cluster_datasource_definition>` which provides information about the past of
|
||||
the :ref:`Cluster <cluster_definition>`.
|
||||
|
||||
Here below is a sequence diagram showing how the Decision Engine builds and
|
||||
maintains the :ref:`cluster data models <cluster_data_model_definition>` that
|
||||
are used by the strategies.

The execution of a strategy then yields a solution composed of a set of
|
||||
:ref:`Actions <action_definition>` as well as a set of :ref:`efficacy
|
||||
indicators <efficacy_indicator_definition>`.
|
||||
|
||||
These :ref:`Actions <action_definition>` are scheduled in time by the
|
||||
:ref:`Watcher Planner <watcher_planner_definition>` (i.e., it generates an
|
||||
:ref:`Action Plan <action_plan_definition>`).

==========
|
||||
|
||||
The following diagram shows the data model of Watcher, especially the
|
||||
functional dependency of objects from the actors (Admin, Customer) point of
|
||||
view (Goals, Audits, Action Plans, ...):

|
||||
=================
|
||||
|
||||
The following paragraph shows the messages exchanged between the different
|
||||
components of Watcher for the most often used scenarios.
|
||||
|
||||
.. _sequence_diagrams_create_audit_template:
|
||||
|
||||
Create a new Audit Template
|
||||
---------------------------
|
||||
|
||||
The :ref:`Administrator <administrator_definition>` first creates an
|
||||
:ref:`Audit template <audit_template_definition>` providing at least the
|
||||
following parameters:
|
||||
|
||||
- A name
|
||||
- A goal to achieve
|
||||
- An optional strategy
|
||||
|
||||
.. image:: ./images/sequence_create_audit_template.png
|
||||
:width: 100%
|
||||
|
||||
The `Watcher API`_ makes sure that both the specified goal (mandatory) and
|
||||
its associated strategy (optional) are registered inside the :ref:`Watcher
|
||||
Database <watcher_database_definition>` before storing a new audit template in
|
||||
the :ref:`Watcher Database <watcher_database_definition>`.
|
||||
|
||||
.. _sequence_diagrams_create_and_launch_audit:
|
||||
|
||||
Create and launch a new Audit
|
||||
-----------------------------
|
||||
|
||||
The :ref:`Administrator <administrator_definition>` can then launch a new
|
||||
:ref:`Audit <audit_definition>` by providing at least the unique UUID of the
|
||||
previously created :ref:`Audit template <audit_template_definition>`:
|
||||
|
||||
.. image:: ./images/sequence_create_and_launch_audit.png
|
||||
:width: 100%
|
||||
|
||||
The :ref:`Administrator <administrator_definition>` also can specify type of
|
||||
Audit and interval (in case of CONTINUOUS type). There is two types of Audit:
|
||||
ONESHOT and CONTINUOUS. Oneshot Audit is launched once and if it succeeded
|
||||
executed new action plan list will be provided. Continuous Audit creates
|
||||
action plans with specified interval (in seconds); if action plan
|
||||
has been created, all previous action plans get CANCELLED state.
|
||||
|
||||
A message is sent on the :ref:`AMQP bus <amqp_bus_definition>` which triggers
|
||||
the Audit in the
|
||||
:ref:`Watcher Decision Engine <watcher_decision_engine_definition>`:
|
||||
|
||||
.. image:: ./images/sequence_trigger_audit_in_decision_engine.png
|
||||
:width: 100%
|
||||
|
||||
The :ref:`Watcher Decision Engine <watcher_decision_engine_definition>` reads
|
||||
the Audit parameters from the
|
||||
:ref:`Watcher Database <watcher_database_definition>`. It instantiates the
|
||||
appropriate :ref:`strategy <strategy_definition>` (using entry points)
|
||||
given both the :ref:`goal <goal_definition>` and the strategy associated to the
|
||||
parent :ref:`audit template <audit_template_definition>` of the :ref:`audit
|
||||
<audit_definition>`. If no strategy is associated to the audit template, the
|
||||
strategy is dynamically selected by the Decision Engine.
|
||||
|
||||
The :ref:`Watcher Decision Engine <watcher_decision_engine_definition>` also
|
||||
builds the :ref:`Cluster Data Model <cluster_data_model_definition>`. This
|
||||
data model is needed by the :ref:`Strategy <strategy_definition>` to know the
|
||||
current state and topology of the audited
|
||||
:ref:`OpenStack cluster <cluster_definition>`.
|
||||
|
||||
The :ref:`Watcher Decision Engine <watcher_decision_engine_definition>` calls
|
||||
the **execute()** method of the instantiated
|
||||
:ref:`Strategy <strategy_definition>` and provides the data model as an input
|
||||
parameter. This method computes a :ref:`Solution <strategy_definition>` to
|
||||
achieve the goal and returns it to the
|
||||
:ref:`Decision Engine <watcher_decision_engine_definition>`. At this point,
|
||||
actions are not scheduled yet.
|
||||
|
||||
The :ref:`Watcher Decision Engine <watcher_decision_engine_definition>`
|
||||
dynamically loads the :ref:`Watcher Planner <watcher_planner_definition>`
|
||||
implementation which is configured in Watcher (via entry points) and calls the
|
||||
**schedule()** method of this class with the solution as an input parameter.
|
||||
This method finds an appropriate scheduling of
|
||||
:ref:`Actions <action_definition>` taking into account some scheduling rules
|
||||
(such as priorities between actions).
|
||||
It generates a new :ref:`Action Plan <action_plan_definition>` with status
|
||||
**RECOMMENDED** and saves it into the :ref:`Watcher Database
|
||||
<watcher_database_definition>`. The saved action plan is now a scheduled flow
|
||||
of actions to which a global efficacy is associated alongside a number of
|
||||
:ref:`Efficacy Indicators <efficacy_indicator_definition>` as specified by the
|
||||
related :ref:`goal <goal_definition>`.
|
||||
|
||||
If every step executed successfully, the
|
||||
:ref:`Watcher Decision Engine <watcher_decision_engine_definition>` updates
|
||||
the current status of the Audit to **SUCCEEDED** in the
|
||||
:ref:`Watcher Database <watcher_database_definition>` and sends a notification
|
||||
on the bus to inform other components that the :ref:`Audit <audit_definition>`
|
||||
was successful.
|
||||
|
||||
This internal workflow the Decision Engine follows to conduct an audit can be
|
||||
seen in the sequence diagram here below:
|
||||
|
||||
.. image:: ./images/sequence_from_audit_execution_to_actionplan_creation.png

||||
.. _sequence_diagrams_launch_action_plan:
|
||||
|
||||
Launch Action Plan
|
||||
------------------
|
||||
|
||||
The :ref:`Administrator <administrator_definition>` can then launch the
|
||||
recommended :ref:`Action Plan <action_plan_definition>`:
|
||||
|
||||
.. image:: ./images/sequence_launch_action_plan.png
|
||||
:width: 100%
|
||||
|
||||
A message is sent on the :ref:`AMQP bus <amqp_bus_definition>` which triggers
|
||||
the :ref:`Action Plan <action_plan_definition>` in the
|
||||
:ref:`Watcher Applier <watcher_applier_definition>`:
|
||||
|
||||
.. image:: ./images/sequence_launch_action_plan_in_applier.png
|
||||
:width: 100%
|
||||
|
||||
The :ref:`Watcher Applier <watcher_applier_definition>` will get the
|
||||
description of the flow of :ref:`Actions <action_definition>` from the
|
||||
:ref:`Watcher Database <watcher_database_definition>` and for each
|
||||
:ref:`Action <action_definition>` it will instantiate a corresponding
|
||||
:ref:`Action <action_definition>` handler python class.
|
||||
|
||||
The :ref:`Watcher Applier <watcher_applier_definition>` will then call the
|
||||
following methods of the :ref:`Action <action_definition>` handler:
|
||||
|
||||
- **validate_parameters()**: this method will make sure that all the
|
||||
provided input parameters are valid:
|
||||
|
||||
- If all parameters are valid, the Watcher Applier moves on to the next
|
||||
step.
|
||||
- If it is not, an error is raised and the action is not executed. A
|
||||
notification is sent on the bus informing other components of the
|
||||
failure.
|
||||
|
||||
- **preconditions()**: this method will make sure that all conditions are met
|
||||
before executing the action (for example, it makes sure that an instance
|
||||
still exists before trying to migrate it).
|
||||
- **execute()**: this method is what triggers real commands on other
|
||||
OpenStack services (such as Nova, ...) in order to change target resource
|
||||
state. If the action is successfully executed, a notification message is
|
||||
sent on the bus indicating that the new state of the action is
|
||||
**SUCCEEDED**.
|
||||
|
||||
If every action of the action flow has been executed successfully, a
|
||||
notification is sent on the bus to indicate that the whole
|
||||
:ref:`Action Plan <action_plan_definition>` has **SUCCEEDED**.

Audit State Machine
|
||||
-------------------
|
||||
|
||||
An :ref:`Audit <audit_definition>` has a life-cycle and its current state may
|
||||
be one of the following:
|
||||
|
||||
- **PENDING** : a request for an :ref:`Audit <audit_definition>` has been
|
||||
submitted (either manually by the
|
||||
:ref:`Administrator <administrator_definition>` or automatically via some
|
||||
event handling mechanism) and is in the queue for being processed by the
|
||||
:ref:`Watcher Decision Engine <watcher_decision_engine_definition>`
|
||||
- **ONGOING** : the :ref:`Audit <audit_definition>` is currently being
|
||||
processed by the
|
||||
:ref:`Watcher Decision Engine <watcher_decision_engine_definition>`
|
||||
- **SUCCEEDED** : the :ref:`Audit <audit_definition>` has been executed
|
||||
successfully and at least one solution was found
|
||||
- **FAILED** : an error occurred while executing the
|
||||
:ref:`Audit <audit_definition>`
|
||||
- **DELETED** : the :ref:`Audit <audit_definition>` is still stored in the
|
||||
:ref:`Watcher database <watcher_database_definition>` but is not returned
|
||||
any more through the Watcher APIs.
|
||||
- **CANCELLED** : the :ref:`Audit <audit_definition>` was in **PENDING** or
|
||||
**ONGOING** state and was cancelled by the
|
||||
:ref:`Administrator <administrator_definition>`
|
||||
- **SUSPENDED** : the :ref:`Audit <audit_definition>` was in **ONGOING**
|
||||
state and was suspended by the
|
||||
:ref:`Administrator <administrator_definition>`
|
||||
|
||||
The following diagram shows the different possible states of an
|

:ref:`Audit <audit_definition>` and what event makes the state change to a new

value:

Action Plan State Machine
|
||||
-------------------------
|
||||
|
||||
An :ref:`Action Plan <action_plan_definition>` has a life-cycle and its current
|
||||
state may be one of the following:
|
||||
|
||||
- **RECOMMENDED** : the :ref:`Action Plan <action_plan_definition>` is waiting
|
||||
for a validation from the :ref:`Administrator <administrator_definition>`
|
||||
- **PENDING** : a request for an :ref:`Action Plan <action_plan_definition>`
|
||||
has been submitted (due to an
|
||||
:ref:`Administrator <administrator_definition>` executing an
|
||||
:ref:`Audit <audit_definition>`) and is in the queue for
|
||||
being processed by the :ref:`Watcher Applier <watcher_applier_definition>`
|
||||
- **ONGOING** : the :ref:`Action Plan <action_plan_definition>` is currently
|
||||
being processed by the :ref:`Watcher Applier <watcher_applier_definition>`
|
||||
- **SUCCEEDED** : the :ref:`Action Plan <action_plan_definition>` has been
|
||||
executed successfully (i.e. all :ref:`Actions <action_definition>` that it
|
||||
contains have been executed successfully)
|
||||
- **FAILED** : an error occurred while executing the
|
||||
:ref:`Action Plan <action_plan_definition>`
|
||||
- **DELETED** : the :ref:`Action Plan <action_plan_definition>` is still
|
||||
stored in the :ref:`Watcher database <watcher_database_definition>` but is
|
||||
not returned any more through the Watcher APIs.
|
||||
- **CANCELLED** : the :ref:`Action Plan <action_plan_definition>` was in
|
||||
**RECOMMENDED**, **PENDING** or **ONGOING** state and was cancelled by the
|
||||
:ref:`Administrator <administrator_definition>`
|
||||
- **SUPERSEDED** : the :ref:`Action Plan <action_plan_definition>` was in
|
||||
RECOMMENDED state and was automatically superseded by Watcher, due to an
|
||||
expiration delay or an update of the
|
||||
:ref:`Cluster data model <cluster_data_model_definition>`
|
||||
|

Set up a development environment via DevStack
|
||||
=============================================
|
||||
|
||||
Watcher is currently able to optimize compute resources - specifically Nova
|
||||
compute hosts - via operations such as live migrations. In order for you to
|
||||
fully be able to exercise what Watcher can do, it is necessary to have a
|
||||
multinode environment to use.
|
||||
|
||||
You can set up the Watcher services quickly and easily using a Watcher
|
||||
DevStack plugin. See `PluginModelDocs`_ for information on DevStack's plugin
|
||||
model. To enable the Watcher plugin with DevStack, add the following to the
|
||||
`[[local|localrc]]` section of your controller's `local.conf` to enable the
|
||||
Watcher plugin::
|
||||
|
||||
enable_plugin watcher git://git.openstack.org/openstack/watcher
|
||||
|
||||
For more detailed instructions, see `Detailed DevStack Instructions`_. Check
|
||||
out the `DevStack documentation`_ for more information regarding DevStack.
|
||||
|
||||

||||
|
||||
Detailed DevStack Instructions
|
||||
==============================
|
||||
|
||||
#. Obtain N (where N >= 1) servers (virtual machines preferred for DevStack).
|
||||
One of these servers will be the controller node while the others will be
|
||||
compute nodes. N is preferably >= 3 so that you have at least 2 compute
|
||||
nodes, but in order to stand up the Watcher services only 1 server is
|
||||
needed (i.e., no computes are needed if you want to just experiment with
|
||||
the Watcher services). These servers can be VMs running on your local
|
||||
machine via VirtualBox if you prefer. DevStack currently recommends that
|
||||
you use Ubuntu 14.04 LTS. The servers should also have connections to the
|
||||
same network such that they are all able to communicate with one another.
|
||||
|
||||
#. For each server, clone the DevStack repository and create the stack user::
|
||||
|
||||
sudo apt-get update
|
||||
sudo apt-get install git
|
||||
git clone https://git.openstack.org/openstack-dev/devstack
|
||||
sudo ./devstack/tools/create-stack-user.sh
|
||||
|
||||
Now you have a stack user that is used to run the DevStack processes. You
|
||||
may want to give your stack user a password to allow SSH via a password::
|
||||
|
||||
sudo passwd stack
|
||||
|
||||
#. Switch to the stack user and clone the DevStack repo again::
|
||||
|
||||
sudo su stack
|
||||
cd ~
|
||||
git clone https://git.openstack.org/openstack-dev/devstack
|
||||
|
||||
#. For each compute node, copy the provided `local.conf.compute`_ example file
|
||||
to the compute node's system at ~/devstack/local.conf. Make sure the
|
||||
HOST_IP and SERVICE_HOST values are changed appropriately - i.e., HOST_IP
|
||||
is set to the IP address of the compute node and SERVICE_HOST is set to the
|
||||
IP address of the controller node.
|
||||
|
||||
If you need specific metrics collected (or want to use something other
|
||||
than Ceilometer), be sure to configure it. For example, in the
|
||||
`local.conf.compute`_ example file, the appropriate ceilometer plugins and
|
||||
services are enabled and disabled. If you were using something other than
|
||||
Ceilometer, then you would likely want to configure it likewise. The
|
||||
example file also sets the compute monitors nova configuration option to
|
||||
use the CPU virt driver. If you needed other metrics, it may be necessary
|
||||
to configure similar configuration options for the projects providing those
|
||||
metrics.
|
||||
|
||||
#. For the controller node, copy the provided `local.conf.controller`_ example
|
||||
file to the controller node's system at ~/devstack/local.conf. Make sure
|
||||
the HOST_IP value is changed appropriately - i.e., HOST_IP is set to the IP
|
||||
address of the controller node.
|
||||
|
||||
Note: if you want to use another Watcher git repository (such as a local
|
||||
one), then change the enable plugin line::
|
||||
|
||||
enable_plugin watcher <your_local_git_repo> [optional_branch]
|
||||
|
||||
If you do this, then the Watcher DevStack plugin will try to pull the
|
||||
python-watcherclient repo from <your_local_git_repo>/../, so either make
|
||||
sure that is also available or specify WATCHERCLIENT_REPO in the local.conf
|
||||
file.
|
||||
|
||||
Note: if you want to use a specific branch, specify WATCHER_BRANCH in the
|
||||
local.conf file. By default it will use the master branch.
|
||||
|
||||
Note: watcher-api will default run under apache/httpd, set the variable
|
||||
WATCHER_USE_MOD_WSGI=FALSE if you do not wish to run under apache/httpd.
|
||||
For development environment it is suggested to set WATHCER_USE_MOD_WSGI
|
||||
to FALSE. For Production environment it is suggested to keep it at the
|
||||
default TRUE value.
|
||||
|
||||
#. Start stacking from the controller node::
|
||||
|
||||
./devstack/stack.sh
|
||||
|
||||
#. Start stacking on each of the compute nodes using the same command.
|
||||
|
||||
#. Configure the environment for live migration via NFS. See the
|
||||
`Multi-Node DevStack Environment`_ section for more details.

|
||||
|
||||
Multi-Node DevStack Environment
|
||||
===============================
|
||||
|
||||
Since deploying Watcher with only a single compute node is not very useful, a
|
||||
few tips are given here for enabling a multi-node environment with live
|
||||
migration.
|
||||
|
||||
Configuring NFS Server
|
||||
----------------------
|
||||
|
||||
If you would like to use live migration for shared storage, then the controller
|
||||
can serve as the NFS server if needed::
|
||||
|
||||
sudo apt-get install nfs-kernel-server
|
||||
sudo mkdir -p /nfs/instances
|
||||
sudo chown stack:stack /nfs/instances
|
||||
|
||||
Add an entry to `/etc/exports` with the appropriate gateway and netmask
|
||||
information::
|
||||
|
||||
/nfs/instances <gateway>/<netmask>(rw,fsid=0,insecure,no_subtree_check,async,no_root_squash)
|
||||
|
||||
Export the NFS directories::
|
||||
|
||||
sudo exportfs -ra
|
||||
|
||||
Make sure the NFS server is running::
|
||||
|
||||
sudo service nfs-kernel-server status
|
||||
|
||||
If the server is not running, then start it::
|
||||
|
||||
sudo service nfs-kernel-server start
|
||||
|
||||
Configuring NFS on Compute Node
|
||||
-------------------------------
|
||||
|
||||
Each compute node needs to use the NFS server to hold the instance data::
|
||||
|
||||
sudo apt-get install rpcbind nfs-common
|
||||
mkdir -p /opt/stack/data/instances
|
||||
sudo mount <nfs-server-ip>:/nfs/instances /opt/stack/data/instances
|
||||
|
||||
If you would like to have the NFS directory automatically mounted on reboot,
|
||||
then add the following to `/etc/fstab`::
|
||||
|
||||
<nfs-server-ip>:/nfs/instances /opt/stack/data/instances nfs auto 0 0
|
||||
|
||||
Edit `/etc/libvirt/libvirtd.conf` to make sure the following values are set::
|
||||
|
||||
listen_tls = 0
|
||||
listen_tcp = 1
|
||||
auth_tcp = "none"
|
||||
|
||||
Edit `/etc/default/libvirt-bin`::
|
||||
|
||||
libvirtd_opts="-d -l"
|
||||
|
||||
Restart the libvirt service::
|
||||
|
||||
sudo service libvirt-bin restart
|
||||
|
||||
Setting up SSH keys between compute nodes to enable live migration
|
||||
------------------------------------------------------------------
|
||||
|
||||
In order for live migration to work, SSH keys need to be exchanged between
|
||||
each compute node:
|
||||
|
||||
1. The SOURCE root user's public RSA key (likely in /root/.ssh/id_rsa.pub)
|
||||
needs to be in the DESTINATION stack user's authorized_keys file
|
||||
(~stack/.ssh/authorized_keys). This can be accomplished by manually
|
||||
copying the contents from the file on the SOURCE to the DESTINATION. If
|
||||
you have a password configured for the stack user, then you can use the
|
||||
following command to accomplish the same thing::
|
||||
|
||||
ssh-copy-id -i /root/.ssh/id_rsa.pub stack@DESTINATION
|
||||
|
||||
2. The DESTINATION host's public ECDSA key (/etc/ssh/ssh_host_ecdsa_key.pub)
|
||||
needs to be in the SOURCE root user's known_hosts file
|
||||
(/root/.ssh/known_hosts). This can be accomplished by running the
|
||||
following on the SOURCE machine (hostname must be used)::
|
||||
|
||||
ssh-keyscan -H DEST_HOSTNAME | sudo tee -a /root/.ssh/known_hosts
|
||||
|
||||
In essence, this means that every compute node's root user's public RSA key
|
||||
must exist in every other compute node's stack user's authorized_keys file and
|
||||
every compute node's public ECDSA key needs to be in every other compute
|
||||
node's root user's known_hosts file.
|
||||
|
||||
Disable serial console
|
||||
----------------------
|
||||
|
||||
Serial console needs to be disabled for live migration to work.
|
||||
|
||||
On both the controller and compute node, in /etc/nova/nova.conf
|
||||
|
||||
[serial_console]
|
||||
enabled = False
|
||||
|
||||
Alternatively, in devstack's local.conf:
|
||||
|
||||
[[post-config|$NOVA_CONF]]
|
||||
[serial_console]
|
||||
#enabled=false
|
||||
|
||||
|
||||
VNC server configuration
|
||||
------------------------
|
||||
|
||||
The VNC server listening parameter needs to be set to any address so
|
||||
that the server can accept connections from all of the compute nodes.
|
||||
|
||||
On both the controller and compute node, in /etc/nova/nova.conf
|
||||
|
||||
vncserver_listen = 0.0.0.0
|
||||
|
||||
Alternatively, in devstack's local.conf:
|
||||
|
||||
VNCSERVER_LISTEN=0.0.0.0
|
||||
|
||||
|
||||
Environment final checkup
|
||||
-------------------------
|
||||
|
||||
If you are willing to make sure everything is in order in your DevStack
|
||||
environment, you can run the Watcher Tempest tests which will validate its API
|
||||
but also that you can perform the typical Watcher workflows. To do so, have a
|
||||
look at the :ref:`Tempest tests <tempest_tests>` section which will explain to
|
||||
you how to run them.

=========================================
|
||||
|
||||
This document describes getting the source from watcher `Git repository`_
|
||||
for development purposes.
|
||||
|
||||
To install Watcher from packaging, refer instead to Watcher `User
|
||||
Documentation`_.
|
||||
|

.. _`User Documentation`: https://docs.openstack.org/watcher/latest/
|
||||
|
||||
Prerequisites
|
||||
=============
|
||||
|
||||
This document assumes you are using Ubuntu or Fedora, and that you have the
|
||||
following tools available on your system:
|
||||
|
||||
- Python_ 2.7 and 3.4
|
||||
- git_
|
||||
- setuptools_
|
||||
- pip_
|
||||
- msgfmt (part of the gettext package)
|
||||
- virtualenv and virtualenvwrapper_
|
||||
|
||||
**Reminder**: If you're successfully using a different platform, or a
|
||||
different version of the above, please document your configuration here!
|
||||
|
||||
.. _Python: https://www.python.org/
|
||||
.. _git: https://git-scm.com/
|
||||
.. _setuptools: https://pypi.python.org/pypi/setuptools
|
||||
.. _virtualenvwrapper: https://virtualenvwrapper.readthedocs.io/en/latest/install.html
|
||||
|
||||
Getting the latest code
|
||||
=======================
|
||||
|
||||
Make a clone of the code from our `Git repository`:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ git clone https://git.openstack.org/openstack/watcher.git
|
||||
|
||||
When that is complete, you can:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ cd watcher
|
||||
|
||||
Installing dependencies
|
||||
=======================
|
||||
|
||||
Watcher maintains two lists of dependencies::
|
||||
|
||||
requirements.txt
|
||||
test-requirements.txt
|
||||
|
||||
The first is the list of dependencies needed for running Watcher, the second
|
||||
list includes dependencies used for active development and testing of Watcher
|
||||
itself.
|
||||
|
||||
These dependencies can be installed from PyPi_ using the Python tool pip_.
|
||||
|
||||
.. _PyPi: http://pypi.python.org/
|
||||
.. _pip: http://pypi.python.org/pypi/pip
|
||||
|
||||
However, your system *may* need additional dependencies that `pip` (and by
|
||||
extension, PyPi) cannot satisfy. These dependencies should be installed
|
||||
prior to using `pip`, and the installation method may vary depending on
|
||||
your platform.
|
||||
|
||||
* Ubuntu 14.04::
|
||||
|
||||
$ sudo apt-get install python-dev libssl-dev libmysqlclient-dev libffi-dev
|
||||
|
||||
* Fedora 19+::
|
||||
|
||||
$ sudo yum install openssl-devel libffi-devel mysql-devel
|
||||
|
||||
* CentOS 7::
|
||||
|
||||
$ sudo yum install gcc python-devel libxml2-devel libxslt-devel mariadb-devel
|
||||
|
||||
PyPi Packages and VirtualEnv
|
||||
----------------------------
|
||||
|
||||
We recommend establishing a virtualenv to run Watcher within. virtualenv
|
||||
limits the Python environment to just what you're installing as dependencies,
|
||||
useful to keep a clean environment for working on Watcher.
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ mkvirtualenv watcher
|
||||
$ git clone https://git.openstack.org/openstack/watcher
|
||||
|
||||
# Use 'python setup.py' to link Watcher into Python's site-packages
|
||||
$ cd watcher && python setup.py install
|
||||
|
||||
# Install the dependencies for running Watcher
|
||||
$ pip install -r ./requirements.txt
|
||||
|
||||
# Install the dependencies for developing, testing, and running Watcher
|
||||
$ pip install -r ./test-requirements.txt
|
||||
|
||||
This will create a local virtual environment in the directory ``$WORKON_HOME``.
|
||||
The virtual environment can be disabled using the command:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ deactivate
|
||||
|
||||
You can re-activate this virtualenv for your current shell using:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ workon watcher
|
||||
|
||||
For more information on virtual environments, see virtualenv_.
|
||||
|
||||
.. _virtualenv: http://www.virtualenv.org/
|
||||
|
||||
|
||||
|
||||
Verifying Watcher is set up
|
||||
===========================
|
||||
|
||||
Once set up, either directly or within a virtualenv, you should be able to
|
||||
invoke Python and import the libraries. If you're using a virtualenv, don't
|
||||
forget to activate it:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ workon watcher
|
||||
|
||||
You should then be able to `import watcher` using Python without issue:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ python -c "import watcher"
|
||||
|
||||
If you can import watcher without a traceback, you should be ready to develop.
|
||||
|
||||
Run Watcher tests
|
||||
=================
|
||||
|
||||
Watcher provides both :ref:`unit tests <unit_tests>` and
|
||||
:ref:`functional/tempest tests <tempest_tests>`. Please refer to :doc:`testing`
|
||||
to understand how to run them.
|
||||
|
||||
|
||||
Build the Watcher documentation
|
||||
===============================
|
||||
|
||||
You can easily build the HTML documentation from ``doc/source`` files, by using
|
||||
``tox``:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ workon watcher
|
||||
|
||||
(watcher) $ cd watcher
|
||||
(watcher) $ tox -edocs
|
||||
|
||||
The HTML files are available into ``doc/build`` directory.
|
||||
|
||||
|
||||
Configure the Watcher services
|
||||
==============================
|
||||
|
||||
Watcher services require a configuration file. Use tox to generate
|
||||
a sample configuration file that can be used to get started:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ tox -e genconfig
|
||||
$ cp etc/watcher.conf.sample etc/watcher.conf
|
||||
|
||||
Most of the default configuration should be enough to get you going, but you
|
||||
still need to configure the following sections:
|
||||
|
||||
- The ``[database]`` section to configure the
|
||||
:ref:`Watcher database <watcher-db_configuration>`
|
||||
- The ``[keystone_authtoken]`` section to configure the
|
||||
:ref:`Identity service <identity-service_configuration>` i.e. Keystone
|
||||
- The ``[watcher_messaging]`` section to configure the OpenStack AMQP-based
|
||||
message bus
|
||||
|
||||
So if you need some more details on how to configure one or more of these
|
||||
sections, please do have a look at :doc:`../deploy/configuration` before
|
||||
continuing.
|
||||
|
||||
|
||||
Create Watcher SQL database
|
||||
===========================
|
||||
|
||||
When initially getting set up, after you've configured which databases to use,
|
||||
you're probably going to need to run the following to your database schema in
|
||||
place:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ workon watcher
|
||||
|
||||
(watcher) $ watcher-db-manage create_schema
|
||||
|
||||
|
||||
Running Watcher services
|
||||
========================
|
||||
|
||||
To run the Watcher API service, use:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ workon watcher
|
||||
|
||||
(watcher) $ watcher-api
|
||||
|
||||
To run the Watcher Decision Engine service, use:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ workon watcher
|
||||
|
||||
(watcher) $ watcher-decision-engine
|
||||
|
||||
To run the Watcher Applier service, use:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ workon watcher
|
||||
|
||||
(watcher) $ watcher-applier
|
||||
|
||||
Default configuration of these services are available into ``/etc/watcher``
|
||||
directory. See :doc:`../deploy/configuration` for details on how Watcher is
|
||||
configured. By default, Watcher is configured with SQL backends.
|
||||
|
||||
|
||||
Interact with Watcher
|
||||
=====================
|
||||
|
||||
You can also interact with Watcher through its REST API. There is a Python
|
||||
Watcher client library `python-watcherclient`_ which interacts exclusively
|
||||
through the REST API, and which Watcher itself uses to provide its command-line
|
||||
interface.
|
||||
|
||||
.. _`python-watcherclient`: https://github.com/openstack/python-watcherclient
|
||||
|
||||
There is also an Horizon plugin for Watcher `watcher-dashboard`_ which
|
||||
allows to interact with Watcher through a web-based interface.
|
||||
|
||||
.. _`watcher-dashboard`: https://github.com/openstack/watcher-dashboard
|
||||
|
||||
|
||||
Exercising the Watcher Services locally
|
||||
=======================================
|
||||
|
||||
If you would like to exercise the Watcher services in isolation within a local
|
||||
virtual environment, you can do this without starting any other OpenStack
|
||||
services. For example, this is useful for rapidly prototyping and debugging
|
||||
interactions over the RPC channel, testing database migrations, and so forth.
|
||||
|
||||
You will find in the `watcher-tools`_ project, Ansible playbooks and Docker
|
||||
template files to easily play with Watcher services within a minimal OpenStack
|
||||
isolated environment (Identity, Message Bus, SQL database, Horizon, ...).

|

==================
|

Build a new action
|
||||
==================
|
||||
|
||||
Watcher Applier has an external :ref:`action <action_definition>` plugin
|
||||
interface which gives anyone the ability to integrate an external
|
||||
:ref:`action <action_definition>` in order to extend the initial set of actions
|
||||
Watcher provides.
|
||||
|
||||
This section gives some guidelines on how to implement and integrate custom
|
||||
actions with Watcher.
|
||||
|
||||
|
||||
Creating a new plugin
|
||||
=====================
|
||||
|
||||
First of all you have to extend the base :py:class:`BaseAction` class which
|
||||
defines a set of abstract methods and/or properties that you will have to
|
||||
implement:
|
||||
|
||||
- The :py:attr:`~.BaseAction.schema` is an abstract property that you have to
|
||||
implement. This is the first function to be called by the
|
||||
:ref:`applier <watcher_applier_definition>` before any further processing
|
||||
and its role is to validate the input parameters that were provided to it.
|
||||
- The :py:meth:`~.BaseAction.pre_condition` is called before the execution of
|
||||
an action. This method is a hook that can be used to perform some
|
||||
initializations or to make some more advanced validation on its input
|
||||
parameters. If you wish to block the execution based on this factor, you
|
||||
simply have to ``raise`` an exception.
|
||||
- The :py:meth:`~.BaseAction.post_condition` is called after the execution of
|
||||
an action. As this function is called regardless of whether an action
|
||||
succeeded or not, this can prove itself useful to perform cleanup
|
||||
operations.
|
||||
- The :py:meth:`~.BaseAction.execute` is the main component of an action.
|
||||
This is where you should implement the logic of your action.
|
||||
- The :py:meth:`~.BaseAction.revert` allows you to roll back the targeted
|
||||
resource to its original state following a faulty execution. Indeed, this
|
||||
method is called by the workflow engine whenever an action raises an
|
||||
exception.
|
||||
|
||||
Here is an example showing how you can write a plugin called ``DummyAction``:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
# Filepath = <PROJECT_DIR>/thirdparty/dummy.py
|
||||
# Import path = thirdparty.dummy
|
||||
import voluptuous
|
||||
|
||||
from watcher.applier.actions import base
|
||||
|
||||
|
||||
class DummyAction(base.BaseAction):
|
||||
|
||||
@property
|
||||
def schema(self):
|
||||
return voluptuous.Schema({})
|
||||
|
||||
def execute(self):
|
||||
# Does nothing
|
||||
pass # Only returning False is considered as a failure
|
||||
|
||||
def revert(self):
|
||||
# Does nothing
|
||||
pass
|
||||
|
||||
def pre_condition(self):
|
||||
# No pre-checks are done here
|
||||
pass
|
||||
|
||||
def post_condition(self):
|
||||
# Nothing done here
|
||||
pass
|
||||
|
||||
|
||||
This implementation is the most basic one. So in order to get a better
|
||||
understanding on how to implement a more advanced action, have a look at the
|
||||
:py:class:`~watcher.applier.actions.migration.Migrate` class.
|
||||
|
||||
Input validation
|
||||
----------------
|
||||
|
||||
As you can see in the previous example, we are using `Voluptuous`_ to validate
|
||||
the input parameters of an action. So if you want to learn more about how to
|
||||
work with `Voluptuous`_, you can have a look at their `documentation`_:
|
||||
|
||||
.. _Voluptuous: https://github.com/alecthomas/voluptuous
|
||||
.. _documentation: https://github.com/alecthomas/voluptuous/blob/master/README.md
|
||||
|
||||
|
||||
Define configuration parameters
|
||||
===============================
|
||||
|
||||
At this point, you have a fully functional action. However, in more complex
|
||||
implementation, you may want to define some configuration options so one can
|
||||
tune the action to its needs. To do so, you can implement the
|
||||
:py:meth:`~.Loadable.get_config_opts` class method as followed:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
from oslo_config import cfg
|
||||
|
||||
class DummyAction(base.BaseAction):
|
||||
|
||||
# [...]
|
||||
|
||||
def execute(self):
|
||||
assert self.config.test_opt == 0
|
||||
|
||||
@classmethod
|
||||
def get_config_opts(cls):
|
||||
return super(
|
||||
DummyAction, cls).get_config_opts() + [
|
||||
cfg.StrOpt('test_opt', help="Demo Option.", default=0),
|
||||
# Some more options ...
|
||||
]
|
||||
|
||||
|
||||
The configuration options defined within this class method will be included
|
||||
within the global ``watcher.conf`` configuration file under a section named by
|
||||
convention: ``{namespace}.{plugin_name}``. In our case, the ``watcher.conf``
|
||||
configuration would have to be modified as followed:
|
||||
|
||||
.. code-block:: ini
|
||||
|
||||
[watcher_actions.dummy]
|
||||
# Option used for testing.
|
||||
test_opt = test_value
|
||||
|
||||
Then, the configuration options you define within this method will then be
|
||||
injected in each instantiated object via the ``config`` parameter of the
|
||||
:py:meth:`~.BaseAction.__init__` method.
|
||||
|
||||
|
||||
Abstract Plugin Class
|
||||
=====================
|
||||
|
||||
Here below is the abstract ``BaseAction`` class that every single action
|
||||
should implement:
|
||||
|
||||
.. autoclass:: watcher.applier.actions.base.BaseAction
|
||||
:members:
|
||||
:special-members: __init__
|
||||
:noindex:
|
||||
|
||||
.. py:attribute:: schema
|
||||
|
||||
Defines a Schema that the input parameters shall comply to
|
||||
|
||||
:returns: A schema declaring the input parameters this action should be
|
||||
provided along with their respective constraints
|
||||
(e.g. type, value range, ...)
|
||||
:rtype: :py:class:`voluptuous.Schema` instance
|
||||
|
||||
|
||||
Register a new entry point
|
||||
==========================
|
||||
|
||||
In order for the Watcher Applier to load your new action, the
|
||||
action must be registered as a named entry point under the
|
||||
``watcher_actions`` entry point of your ``setup.py`` file. If you are using
|
||||
pbr_, this entry point should be placed in your ``setup.cfg`` file.
|
||||
|
||||
The name you give to your entry point has to be unique.
|
||||
|
||||
Here below is how you would proceed to register ``DummyAction`` using pbr_:
|
||||
|
||||
.. code-block:: ini
|
||||
|
||||
[entry_points]
|
||||
watcher_actions =
|
||||
dummy = thirdparty.dummy:DummyAction
|
||||
|
||||
.. _pbr: http://docs.openstack.org/developer/pbr/
|
||||
|
||||
|
||||
Using action plugins
|
||||
====================
|
||||
|
||||
The Watcher Applier service will automatically discover any installed plugins
|
||||
when it is restarted. If a Python package containing a custom plugin is
|
||||
installed within the same environment as Watcher, Watcher will automatically
|
||||
make that plugin available for use.
|
||||
|
||||
At this point, you can use your new action plugin in your :ref:`strategy plugin
|
||||
<implement_strategy_plugin>` if you reference it via the use of the
|
||||
:py:meth:`~.Solution.add_action` method:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
# [...]
|
||||
self.solution.add_action(
|
||||
action_type="dummy", # Name of the entry point we registered earlier
|
||||
applies_to="",
|
||||
input_parameters={})
|
||||
|
||||
By doing so, your action will be saved within the Watcher Database, ready to be
|
||||
processed by the planner for creating an action plan which can then be executed
|
||||
by the Watcher Applier via its workflow engine.
|
||||
|
||||
At the last, remember to add the action into the weights in ``watcher.conf``,
|
||||
otherwise you will get an error when the action be referenced in a strategy.
|
||||
|
||||
|
||||
Scheduling of an action plugin
|
||||
==============================
|
||||
|
||||
Watcher provides a basic built-in :ref:`planner <watcher_planner_definition>`
|
||||
which is only able to process the Watcher built-in actions. Therefore, you will
|
||||
either have to use an existing third-party planner or :ref:`implement another
|
||||
planner <implement_planner_plugin>` that will be able to take into account your
|
||||
new action plugin.

Create a third-party plugin for Watcher
|

=======================================
|
||||
|

Watcher provides a plugin architecture which allows anyone to extend the
|
||||
existing functionalities by implementing third-party plugins. This process can
|
||||
be cumbersome so this documentation is there to help you get going as quickly
|
||||
as possible.
|
||||
|
||||
|
||||
Pre-requisites
|
||||
==============
|
||||
|
||||
We assume that you have set up a working Watcher development environment. So if
|
||||
this not already the case, you can check out our documentation which explains
|
||||
how to set up a :ref:`development environment
|
||||
<watcher_developement_environment>`.
|
||||
|
||||
.. _development environment:
|
||||
|
||||
Third party project scaffolding
|
||||
===============================
|
||||
|
||||
First off, we need to create the project structure. To do so, we can use
|
||||
`cookiecutter`_ and the `OpenStack cookiecutter`_ project scaffolder to
|
||||
generate the skeleton of our project::
|
||||
|
||||
$ virtualenv thirdparty
|
||||
$ source thirdparty/bin/activate
|
||||
$ pip install cookiecutter
|
||||
$ cookiecutter https://github.com/openstack-dev/cookiecutter
|
||||
|
||||
The last command will ask you for many information, and If you set
|
||||
``module_name`` and ``repo_name`` as ``thirdparty``, you should end up with a
|
||||
structure that looks like this::
|
||||
|
||||
$ cd thirdparty
|
||||
$ tree .

Implementing a plugin for Watcher
|
||||
=================================
|
||||
|
||||
Now that the project skeleton has been created, you can start the
|
||||
implementation of your plugin. As of now, you can implement the following
|
||||
plugins for Watcher:
|
||||
|
||||
- A :ref:`goal plugin <implement_goal_plugin>`
|
||||
- A :ref:`strategy plugin <implement_strategy_plugin>`
|
||||
- An :ref:`action plugin <implement_action_plugin>`
|
||||
- A :ref:`planner plugin <implement_planner_plugin>`
|
||||
- A workflow engine plugin
|
||||
- A :ref:`cluster data model collector plugin
|
||||
<implement_cluster_data_model_collector_plugin>`
|
||||
|
||||
If you want to learn more on how to implement them, you can refer to their
|
||||
dedicated documentation.

Build a new cluster data model collector
|
||||
========================================
|
||||
|
||||
Watcher Decision Engine has an external cluster data model (CDM) plugin
|
||||
interface which gives anyone the ability to integrate an external cluster data
|
||||
model collector (CDMC) in order to extend the initial set of cluster data model
|
||||
collectors Watcher provides.
|
||||
|
||||
This section gives some guidelines on how to implement and integrate custom
|
||||
cluster data model collectors within Watcher.
|
||||
|
||||
|
||||
Creating a new plugin
|
||||
=====================
|
||||
|
||||
In order to create a new cluster data model collector, you have to:
|
||||
|
||||
- Extend the :py:class:`~.base.BaseClusterDataModelCollector` class.
|
||||
- Implement its :py:meth:`~.BaseClusterDataModelCollector.execute` abstract
|
||||
method to return your entire cluster data model that this method should
|
||||
build.
|
||||
- Implement its :py:meth:`~.Goal.notification_endpoints` abstract property to
|
||||
return the list of all the :py:class:`~.base.NotificationEndpoint` instances
|
||||
that will be responsible for handling incoming notifications in order to
|
||||
incrementally update your cluster data model.
|
||||
|
||||
First of all, you have to extend the :class:`~.BaseClusterDataModelCollector`
|
||||
base class which defines the :py:meth:`~.BaseClusterDataModelCollector.execute`
|
||||
abstract method you will have to implement. This method is responsible for
|
||||
building an entire cluster data model.
|
||||
|
||||
Here is an example showing how you can write a plugin called
|
||||
``DummyClusterDataModelCollector``:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
# Filepath = <PROJECT_DIR>/thirdparty/dummy.py
|
||||
# Import path = thirdparty.dummy
|
||||
|
||||
from watcher.decision_engine.model import model_root
|
||||
from watcher.decision_engine.model.collector import base
|
||||
|
||||
|
||||
class DummyClusterDataModelCollector(base.BaseClusterDataModelCollector):
|
||||
|
||||
def execute(self):
|
||||
model = model_root.ModelRoot()
|
||||
# Do something here...
|
||||
return model
|
||||
|
||||
@property
|
||||
def notification_endpoints(self):
|
||||
return []
|
||||
|
||||
This implementation is the most basic one. So in order to get a better
|
||||
understanding on how to implement a more advanced cluster data model collector,
|
||||
have a look at the :py:class:`~.NovaClusterDataModelCollector` class.
|
||||
|
||||
Define a custom model
|
||||
=====================
|
||||
|
||||
As you may have noticed in the above example, we are reusing an existing model
|
||||
provided by Watcher. However, this model can be easily customized by
|
||||
implementing a new class that would implement the :py:class:`~.Model` abstract
|
||||
base class. Here below is simple example on how to proceed in implementing a
|
||||
custom Model:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
# Filepath = <PROJECT_DIR>/thirdparty/dummy.py
|
||||
# Import path = thirdparty.dummy
|
||||
|
||||
from watcher.decision_engine.model import base as modelbase
|
||||
from watcher.decision_engine.model.collector import base
|
||||
|
||||
|
||||
class MyModel(modelbase.Model):
|
||||
|
||||
def to_string(self):
|
||||
return 'MyModel'
|
||||
|
||||
|
||||
class DummyClusterDataModelCollector(base.BaseClusterDataModelCollector):
|
||||
|
||||
def execute(self):
|
||||
model = MyModel()
|
||||
# Do something here...
|
||||
return model
|
||||
|
||||
@property
|
||||
def notification_endpoints(self):
|
||||
return []
|
||||
|
||||
Here below is the abstract ``Model`` class that every single cluster data model
|
||||
should implement:
|
||||
|
||||
.. autoclass:: watcher.decision_engine.model.base.Model
|
||||
:members:
|
||||
:special-members: __init__
|
||||
:noindex:
|
||||
|
||||
Define configuration parameters
|
||||
===============================
|
||||
|
||||
At this point, you have a fully functional cluster data model collector.
|
||||
By default, cluster data model collectors define a ``period`` option (see
|
||||
:py:meth:`~.BaseClusterDataModelCollector.get_config_opts`) that corresponds
|
||||
to the interval of time between each synchronization of the in-memory model.
|
||||
|
||||
However, in more complex implementation, you may want to define some
|
||||
configuration options so one can tune the cluster data model collector to your
|
||||
needs. To do so, you can implement the :py:meth:`~.Loadable.get_config_opts`
|
||||
class method as followed:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
from oslo_config import cfg
|
||||
from watcher.decision_engine.model import model_root
|
||||
from watcher.decision_engine.model.collector import base
|
||||
|
||||
|
||||
class DummyClusterDataModelCollector(base.BaseClusterDataModelCollector):
|
||||
|
||||
def execute(self):
|
||||
model = model_root.ModelRoot()
|
||||
# Do something here...
|
||||
return model
|
||||
|
||||
@property
|
||||
def notification_endpoints(self):
|
||||
return []
|
||||
|
||||
@classmethod
|
||||
def get_config_opts(cls):
|
||||
return super(
|
||||
DummyClusterDataModelCollector, cls).get_config_opts() + [
|
||||
cfg.StrOpt('test_opt', help="Demo Option.", default=0),
|
||||
# Some more options ...
|
||||
]
|
||||
|
||||
The configuration options defined within this class method will be included
|
||||
within the global ``watcher.conf`` configuration file under a section named by
|
||||
convention: ``{namespace}.{plugin_name}`` (see section :ref:`Register a new
|
||||
entry point <register_new_cdmc_entrypoint>`). The namespace for CDMC plugins is
|
||||
``watcher_cluster_data_model_collectors``, so in our case, the ``watcher.conf``
|
||||
configuration would have to be modified as followed:
|
||||
|
||||
.. code-block:: ini
|
||||
|
||||
[watcher_cluster_data_model_collectors.dummy]
|
||||
# Option used for testing.
|
||||
test_opt = test_value
|
||||
|
||||
Then, the configuration options you define within this method will then be
|
||||
injected in each instantiated object via the ``config`` parameter of the
|
||||
:py:meth:`~.BaseClusterDataModelCollector.__init__` method.
|
||||
|
||||
|
||||
Abstract Plugin Class

||||
=====================

||||

Here below is the abstract ``BaseClusterDataModelCollector`` class that every

||||
single cluster data model collector should implement:

.. autoclass:: watcher.decision_engine.model.collector.base.BaseClusterDataModelCollector
|
||||

|
||||
Register a new entry point
|
||||
==========================
|
||||
|
||||
In order for the Watcher Decision Engine to load your new cluster data model
|
||||
collector, the latter must be registered as a named entry point under the
|
||||
``watcher_cluster_data_model_collectors`` entry point namespace of your
|
||||
``setup.py`` file. If you are using pbr_, this entry point should be placed in
|
||||
your ``setup.cfg`` file.
|
||||
|
||||
The name you give to your entry point has to be unique.
|
||||
|
||||
Here below is how to register ``DummyClusterDataModelCollector`` using pbr_:
|
||||
|
||||
.. code-block:: ini
|
||||
|
||||
[entry_points]
|
||||
watcher_cluster_data_model_collectors =
|
||||
dummy = thirdparty.dummy:DummyClusterDataModelCollector
|
||||
|
||||
.. _pbr: http://docs.openstack.org/developer/pbr/
|
||||
|
||||
|
||||
Add new notification endpoints
|
||||
==============================
|
||||
|
||||
At this point, you have a fully functional cluster data model collector.
|
||||
However, this CDMC is only refreshed periodically via a background scheduler.
|
||||
As you may sometimes execute a strategy with a stale CDM due to a high activity
|
||||
on your infrastructure, you can define some notification endpoints that will be
|
||||
responsible for incrementally updating the CDM based on notifications emitted
|
||||
by other services such as Nova. To do so, you can implement and register a new
|
||||
``DummyEndpoint`` notification endpoint regarding a ``dummy`` event as shown
|
||||
below:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
from watcher.decision_engine.model import model_root
|
||||
from watcher.decision_engine.model.collector import base
|
||||
|
||||
|
||||
class DummyNotification(base.NotificationEndpoint):
|
||||
|
||||
@property
|
||||
def filter_rule(self):
|
||||
return filtering.NotificationFilter(
|
||||
publisher_id=r'.*',
|
||||
event_type=r'^dummy$',
|
||||
)
|
||||
|
||||
def info(self, ctxt, publisher_id, event_type, payload, metadata):
|
||||
# Do some CDM modifications here...
|
||||
pass
|
||||
|
||||
|
||||
class DummyClusterDataModelCollector(base.BaseClusterDataModelCollector):
|
||||
|
||||
def execute(self):
|
||||
model = model_root.ModelRoot()
|
||||
# Do something here...
|
||||
return model
|
||||
|
||||
@property
|
||||
def notification_endpoints(self):
|
||||
return [DummyNotification(self)]
|
||||
|
||||
|
||||
Note that if the event you are trying to listen to is published by a new
|
||||
service, you may have to also add a new topic Watcher will have to subscribe to
|
||||
in the ``notification_topics`` option of the ``[watcher_decision_engine]``
|
||||
section.
|
||||
|
||||
|
||||
Using cluster data model collector plugins
|
||||
==========================================
|
||||
|
||||
The Watcher Decision Engine service will automatically discover any installed
|
||||
plugins when it is restarted. If a Python package containing a custom plugin is
|
||||
installed within the same environment as Watcher, Watcher will automatically
|
||||
make that plugin available for use.
|
||||
|
||||
At this point, you can use your new cluster data model plugin in your
|
||||
:ref:`strategy plugin <implement_strategy_plugin>` by using the
|
||||
:py:attr:`~.BaseStrategy.collector_manager` property as followed:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
# [...]
|
||||
dummy_collector = self.collector_manager.get_cluster_model_collector(
|
||||
"dummy") # "dummy" is the name of the entry point we declared earlier
|
||||
dummy_model = dummy_collector.get_latest_cluster_data_model()
|
||||
# Do some stuff with this model

Build a new goal
|

================
|
||||
|
||||
Watcher Decision Engine has an external :ref:`goal <goal_definition>`
|
||||
plugin interface which gives anyone the ability to integrate an external
|
||||
goal which can be achieved by a :ref:`strategy <strategy_definition>`.
|
||||
|
||||
This section gives some guidelines on how to implement and integrate custom
|
||||
goals with Watcher. If you wish to create a third-party package for your
|
||||
plugin, you can refer to our :ref:`documentation for third-party package
|
||||
creation <plugin-base_setup>`.
|
||||
|
||||
|
||||
Pre-requisites
|
||||
==============
|
||||
|
||||
Before using any goal, please make sure that none of the existing goals fit
|
||||
your needs. Indeed, the underlying value of defining a goal is to be able to
|
||||
compare the efficacy of the action plans resulting from the various strategies
|
||||
satisfying the same goal. By doing so, Watcher can assist the administrator
|
||||
in his choices.
|
||||
|
||||
|
||||
Create a new plugin
|
||||
===================
|
||||
|
||||
In order to create a new goal, you have to:
|
||||
|
||||
- Extend the :py:class:`~.base.Goal` class.
|
||||
- Implement its :py:meth:`~.Goal.get_name` class method to return the
|
||||
**unique** ID of the new goal you want to create. This unique ID should
|
||||
be the same as the name of :ref:`the entry point you will declare later on
|
||||
<goal_plugin_add_entrypoint>`.
|
||||
- Implement its :py:meth:`~.Goal.get_display_name` class method to
|
||||
return the translated display name of the goal you want to create.
|
||||
Note: Do not use a variable to return the translated string so it can be
|
||||
automatically collected by the translation tool.
|
||||
- Implement its :py:meth:`~.Goal.get_translatable_display_name`
|
||||
class method to return the translation key (actually the english display
|
||||
name) of your new goal. The value return should be the same as the
|
||||
string translated in :py:meth:`~.Goal.get_display_name`.
|
||||
- Implement its :py:meth:`~.Goal.get_efficacy_specification` method to return
|
||||
the :ref:`efficacy specification <efficacy_specification_definition>` for
|
||||
your goal.
|
||||
|
||||
Here is an example showing how you can define a new ``NewGoal`` goal plugin:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
# filepath: thirdparty/new.py
|
||||
# import path: thirdparty.new
|
||||
|
||||
from watcher._i18n import _
|
||||
from watcher.decision_engine.goal import base
|
||||
from watcher.decision_engine.goal.efficacy import specs
|
||||
|
||||
class NewGoal(base.Goal):
|
||||
|
||||
@classmethod
|
||||
def get_name(cls):
|
||||
return "new_goal" # Will be the name of the entry point
|
||||
|
||||
@classmethod
|
||||
def get_display_name(cls):
|
||||
return _("New Goal")
|
||||
|
||||
@classmethod
|
||||
def get_translatable_display_name(cls):
|
||||
return "New Goal"
|
||||
|
||||
@classmethod
|
||||
def get_efficacy_specification(cls):
|
||||
return specs.Unclassified()
|
||||
|
||||
|
||||
As you may have noticed, the :py:meth:`~.Goal.get_efficacy_specification`
|
||||
method returns an :py:meth:`~.Unclassified` instance which
|
||||
is provided by Watcher. This efficacy specification is useful during the
|
||||
development process of your goal as it corresponds to an empty specification.
|
||||
If you want to learn more about what efficacy specifications are used for or to
|
||||
define your own efficacy specification, please refer to the :ref:`related
|
||||
section below <implement_efficacy_specification>`.
|
||||
|
||||
|
||||
Abstract Plugin Class
|
||||
=====================
|
||||
|
||||
Here below is the abstract :py:class:`~.base.Goal` class:
|
||||
|
||||
.. autoclass:: watcher.decision_engine.goal.base.Goal
|
||||
:members:
|

:noindex:
|
||||
|
||||
.. _goal_plugin_add_entrypoint:
|
||||
|
||||
Add a new entry point
|
||||
=====================
|
||||
|
||||
In order for the Watcher Decision Engine to load your new goal, the
|
||||
goal must be registered as a named entry point under the ``watcher_goals``
|
||||
entry point namespace of your ``setup.py`` file. If you are using pbr_, this
|
||||
entry point should be placed in your ``setup.cfg`` file.
|
||||
|
||||
The name you give to your entry point has to be unique and should be the same
|
||||
as the value returned by the :py:meth:`~.base.Goal.get_name` class method of
|
||||
your goal.
|
||||
|
||||
Here below is how you would proceed to register ``NewGoal`` using pbr_:
|
||||
|
||||
.. code-block:: ini
|
||||
|
||||
[entry_points]
|
||||
watcher_goals =
|
||||
new_goal = thirdparty.new:NewGoal
|
||||
|
||||
|
||||
To get a better understanding on how to implement a more advanced goal,
|
||||
have a look at the :py:class:`~.ServerConsolidation` class.

||||

.. _implement_efficacy_specification:
|
||||
|
||||
Implement a customized efficacy specification
|
||||
=============================================
|
||||
|
||||
What is it for?
|
||||
---------------
|
||||
|
||||
Efficacy specifications define a set of specifications for a given goal.
|
||||
These specifications actually define a list of indicators which are to be used
|
||||
to compute a global efficacy that outlines how well a strategy performed when
|
||||
trying to achieve the goal it is associated to.
|
||||
|
||||
The idea behind such specification is to give the administrator the possibility
|
||||
to run an audit using different strategies satisfying the same goal and be able
|
||||
to judge how they performed at a glance.
|
||||
|
||||
|
||||
Implementation
|
||||
--------------
|
||||
|
||||
In order to create a new efficacy specification, you have to:
|
||||
|
||||
- Extend the :py:class:`~.EfficacySpecification` class.
|
||||
- Implement :py:meth:`~.EfficacySpecification.get_indicators_specifications`
|
||||
by returning a list of :py:class:`~.IndicatorSpecification` instances.
|
||||
|
||||
* Each :py:class:`~.IndicatorSpecification` instance should actually extend
|
||||
the latter.
|
||||
* Each indicator specification should have a **unique name** which should be
|
||||
a valid Python variable name.
|
||||
* They should implement the :py:attr:`~.EfficacySpecification.schema`
|
||||
abstract property by returning a :py:class:`~.voluptuous.Schema` instance.
|
||||
This schema is the contract the strategy will have to comply with when
|
||||
setting the value associated to the indicator specification within its
|
||||
solution (see the :ref:`architecture of Watcher
|
||||
<sequence_diagrams_create_and_launch_audit>` for more information on
|
||||
the audit execution workflow).
|
||||
|
||||
- Implement the :py:meth:`~.EfficacySpecification.get_global_efficacy` method:
|
||||
it should compute the global efficacy for the goal it achieves based on the
|
||||
efficacy indicators you just defined.
|
||||
|
||||
Here below is an example of an efficacy specification containing one indicator
|
||||
specification:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
from watcher._i18n import _
|
||||
from watcher.decision_engine.goal.efficacy import base as efficacy_base
|
||||
from watcher.decision_engine.goal.efficacy import indicators
|
||||
from watcher.decision_engine.solution import efficacy
|
||||
|
||||
|
||||
class IndicatorExample(IndicatorSpecification):
|
||||
def __init__(self):
|
||||
super(IndicatorExample, self).__init__(
|
||||
name="indicator_example",
|
||||
description=_("Example of indicator specification."),
|
||||
unit=None,
|
||||
)
|
||||
|
||||
@property
|
||||
def schema(self):
|
||||
return voluptuous.Schema(voluptuous.Range(min=0), required=True)
|
||||
|
||||
|
||||
class UnclassifiedStrategySpecification(efficacy_base.EfficacySpecification):
|
||||
|
||||
def get_indicators_specifications(self):
|
||||
return [IndicatorExample()]
|
||||
|
||||
def get_global_efficacy(self, indicators_map):
|
||||
return efficacy.Indicator(
|
||||
name="global_efficacy_indicator",
|
||||
description="Example of global efficacy indicator",
|
||||
unit="%",
|
||||
value=indicators_map.indicator_example % 100)
|
||||
|
||||
|
||||
To get a better understanding on how to implement an efficacy specification,
|
||||
have a look at :py:class:`~.ServerConsolidationSpecification`.
|
||||
|
||||
Also, if you want to see a concrete example of an indicator specification,
|
||||
have a look at :py:class:`~.ReleasedComputeNodesCount`.

Build a new planner
|

===================
|
||||
|
||||
Watcher :ref:`Decision Engine <watcher_decision_engine_definition>` has an
|
||||
external :ref:`planner <watcher_planner_definition>` plugin interface which
|
||||
gives anyone the ability to integrate an external :ref:`planner
|
||||
<watcher_planner_definition>` in order to extend the initial set of planners
|
||||
Watcher provides.
|
||||
|

This section gives some guidelines on how to implement and integrate custom
|
||||
planners with Watcher.
|
||||
|
||||
.. _Decision Engine: watcher_decision_engine_definition
|
||||
|
||||
Creating a new plugin
|
||||
=====================
|
||||
|
||||
First of all you have to extend the base :py:class:`~.BasePlanner` class which
|
||||
defines an abstract method that you will have to implement. The
|
||||
:py:meth:`~.BasePlanner.schedule` is the method being called by the Decision
|
||||
Engine to schedule a given solution (:py:class:`~.BaseSolution`) into an
|
||||
:ref:`action plan <action_plan_definition>` by ordering/sequencing an unordered
|
||||
set of actions contained in the proposed solution (for more details, see
|
||||
:ref:`definition of a solution <solution_definition>`).
|
||||
|
||||
Here is an example showing how you can write a planner plugin called
|
||||
``DummyPlanner``:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
# Filepath = third-party/third_party/dummy.py
|
||||
# Import path = third_party.dummy
|
||||
from oslo_utils import uuidutils
|
||||
from watcher.decision_engine.planner import base
|
||||
|
||||
|
||||
class DummyPlanner(base.BasePlanner):
|
||||
|
||||
def _create_action_plan(self, context, audit_id):
|
||||
action_plan_dict = {
|
||||
'uuid': uuidutils.generate_uuid(),
|
||||
'audit_id': audit_id,
|
||||
'first_action_id': None,
|
||||
'state': objects.action_plan.State.RECOMMENDED
|
||||
}
|
||||
|
||||
new_action_plan = objects.ActionPlan(context, **action_plan_dict)
|
||||
new_action_plan.create(context)
|
||||
new_action_plan.save()
|
||||
return new_action_plan
|
||||
|
||||
def schedule(self, context, audit_id, solution):
|
||||
# Empty action plan
|
||||
action_plan = self._create_action_plan(context, audit_id)
|
||||
# todo: You need to create the workflow of actions here
|
||||
# and attach it to the action plan
|
||||
return action_plan
|
||||
|
||||
This implementation is the most basic one. So if you want to have more advanced
|
||||
examples, have a look at the implementation of planners already provided by
|
||||
Watcher like :py:class:`~.DefaultPlanner`. A list with all available planner
|
||||
plugins can be found :ref:`here <watcher_planners>`.
|
||||
|
||||
|
||||
Define configuration parameters
|
||||
===============================
|
||||
|
||||
At this point, you have a fully functional planner. However, in more complex
|
||||
implementation, you may want to define some configuration options so one can
|
||||
tune the planner to its needs. To do so, you can implement the
|
||||
:py:meth:`~.Loadable.get_config_opts` class method as followed:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
from oslo_config import cfg
|
||||
|
||||
class DummyPlanner(base.BasePlanner):
|
||||
|
||||
# [...]
|
||||
|
||||
def schedule(self, context, audit_uuid, solution):
|
||||
assert self.config.test_opt == 0
|
||||
# [...]
|
||||
|
||||
@classmethod
|
||||
def get_config_opts(cls):
|
||||
return super(
|
||||
DummyPlanner, cls).get_config_opts() + [
|
||||
cfg.StrOpt('test_opt', help="Demo Option.", default=0),
|
||||
# Some more options ...
|
||||
]
|
||||
|
||||
The configuration options defined within this class method will be included
|
||||
within the global ``watcher.conf`` configuration file under a section named by
|
||||
convention: ``{namespace}.{plugin_name}``. In our case, the ``watcher.conf``
|
||||
configuration would have to be modified as followed:
|
||||
|
||||
.. code-block:: ini
|
||||
|
||||
[watcher_planners.dummy]
|
||||
# Option used for testing.
|
||||
test_opt = test_value
|
||||
|
||||
Then, the configuration options you define within this method will then be
|
||||
injected in each instantiated object via the ``config`` parameter of the
|
||||
:py:meth:`~.BasePlanner.__init__` method.
|
||||
|
||||
|
||||
Abstract Plugin Class
|
||||
=====================
|
||||
|
||||
Here below is the abstract ``BasePlanner`` class that every single planner
|
||||
should implement:
|
||||
|
||||
.. autoclass:: watcher.decision_engine.planner.base.BasePlanner
|
||||
:members:
|
||||
:special-members: __init__
|
||||
:noindex:
|
||||
|
||||
|
||||
Register a new entry point
|
||||
==========================
|
||||
|
||||
In order for the Watcher Decision Engine to load your new planner, the
|
||||
latter must be registered as a new entry point under the
|
||||
``watcher_planners`` entry point namespace of your ``setup.py`` file. If you
|
||||
are using pbr_, this entry point should be placed in your ``setup.cfg`` file.
|
||||
|
||||
The name you give to your entry point has to be unique.
|
||||
|
||||
Here below is how you would proceed to register ``DummyPlanner`` using pbr_:
|
||||
|
||||
.. code-block:: ini
|
||||
|
||||
[entry_points]
|
||||
watcher_planners =
|
||||
dummy = third_party.dummy:DummyPlanner
|
||||
|
||||
.. _pbr: http://docs.openstack.org/developer/pbr/
|
||||
|
||||
|
||||
Using planner plugins
|
||||
=====================
|
||||
|
||||
The :ref:`Watcher Decision Engine <watcher_decision_engine_definition>` service
|
||||
will automatically discover any installed plugins when it is started. This
|
||||
means that if Watcher is already running when you install your plugin, you will
|
||||
have to restart the related Watcher services. If a Python package containing a
|
||||
custom plugin is installed within the same environment as Watcher, Watcher will
|
||||
automatically make that plugin available for use.
|
||||
|
||||
At this point, Watcher will use your new planner if you referenced it in the
|
||||
``planner`` option under the ``[watcher_planner]`` section of your
|
||||
``watcher.conf`` configuration file when you started it. For example, if you
|
||||
want to use the ``dummy`` planner you just installed, you would have to
|
||||
select it as followed:
|
||||
|
||||
.. code-block:: ini
|
||||
|
||||
[watcher_planner]
|
||||
planner = dummy
|
||||
|
||||
As you may have noticed, only a single planner implementation can be activated
|
||||
at a time, so make sure it is generic enough to support all your strategies
|
||||
and actions.

==========================
|

Build a new scoring engine
|
||||
==========================
|
||||
|
||||
Watcher Decision Engine has an external :ref:`scoring engine
|
||||
<scoring_engine_definition>` plugin interface which gives anyone the ability
|
||||
to integrate an external scoring engine in order to make use of it in a
|
||||
:ref:`strategy <strategy_definition>`.
|
||||
|
||||
This section gives some guidelines on how to implement and integrate custom
|
||||
scoring engines with Watcher. If you wish to create a third-party package for
|
||||
your plugin, you can refer to our :ref:`documentation for third-party package
|
||||
creation <plugin-base_setup>`.
|
||||
|
||||
|
||||
Pre-requisites
|
||||
==============
|
||||
|
||||
Because scoring engines execute a purely mathematical tasks, they typically do
|
||||
not have any additional dependencies. Additional requirements might be defined
|
||||
by specific scoring engine implementations. For example, some scoring engines
|
||||
might require to prepare learning data, which has to be loaded during the
|
||||
scoring engine startup. Some other might require some external services to be
|
||||
available (e.g. if the scoring infrastructure is running in the cloud).
|
||||
|
||||
|
||||
Create a new scoring engine plugin
|
||||
==================================
|
||||
|
||||
In order to create a new scoring engine you have to:
|
||||
|
||||
- Extend the :py:class:`~.ScoringEngine` class
|
||||
- Implement its :py:meth:`~.ScoringEngine.get_name` method to return the
|
||||
**unique** ID of the new scoring engine you want to create. This unique ID
|
||||
should be the same as the name of :ref:`the entry point we will declare later
|
||||
on <scoring_engine_plugin_add_entrypoint>`.
|
||||
- Implement its :py:meth:`~.ScoringEngine.get_description` method to return the
|
||||
user-friendly description of the implemented scoring engine. It might contain
|
||||
information about algorithm used, learning data etc.
|
||||
- Implement its :py:meth:`~.ScoringEngine.get_metainfo` method to return the
|
||||
machine-friendly metadata about this scoring engine. For example, it could be
|
||||
a JSON formatted text with information about the data model used, its input
|
||||
and output data format, column names, etc.
|
||||
- Implement its :py:meth:`~.ScoringEngine.calculate_score` method to return the
|
||||
result calculated by this scoring engine.
|
||||
|
||||
Here is an example showing how you can write a plugin called ``NewScorer``:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
# filepath: thirdparty/new.py
|
||||
# import path: thirdparty.new
|
||||
from watcher.decision_engine.scoring import base
|
||||
|
||||
|
||||
class NewScorer(base.ScoringEngine):
|
||||
|
||||
def get_name(self):
|
||||
return 'new_scorer'
|
||||
|
||||
def get_description(self):
|
||||
return ''
|
||||
|
||||
def get_metainfo(self):
|
||||
return """{
|
||||
"feature_columns": [
|
||||
"column1",
|
||||
"column2",
|
||||
"column3"],
|
||||
"result_columns": [
|
||||
"value",
|
||||
"probability"]
|
||||
}"""
|
||||
|
||||
def calculate_score(self, features):
|
||||
return '[12, 0.83]'
|
||||
|
||||
As you can see in the above example, the
|
||||
:py:meth:`~.ScoringEngine.calculate_score` method returns a string. Both this
|
||||
class and the client (caller) should perform all the necessary serialization
|
||||
or deserialization.
|
||||
|
||||
|
||||
(Optional) Create a new scoring engine container plugin
|
||||
=======================================================
|
||||
|
||||
Optionally, it's possible to implement a container plugin, which can return a
|
||||
list of scoring engines. This list can be re-evaluated multiple times during
|
||||
the lifecycle of :ref:`Watcher Decision Engine
|
||||
<watcher_decision_engine_definition>` and synchronized with :ref:`Watcher
|
||||
Database <watcher_database_definition>` using the ``watcher-sync`` command line
|
||||
tool.
|
||||
|
||||
Below is an example of a container using some scoring engine implementation
|
||||
that is simply made of a client responsible for communicating with a real
|
||||
scoring engine deployed as a web service on external servers:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
class NewScoringContainer(base.ScoringEngineContainer):
|
||||
|
||||
@classmethod
|
||||
def get_scoring_engine_list(self):
|
||||
return [
|
||||
RemoteScoringEngine(
|
||||
name='scoring_engine1',
|
||||
description='Some remote Scoring Engine 1',
|
||||
remote_url='http://engine1.example.com/score'),
|
||||
RemoteScoringEngine(
|
||||
name='scoring_engine2',
|
||||
description='Some remote Scoring Engine 2',
|
||||
remote_url='http://engine2.example.com/score'),
|
||||
]
|
||||
|
||||
|
||||
Abstract Plugin Class
|
||||
=====================
|
||||
|
||||
Here below is the abstract :py:class:`~.ScoringEngine` class:
|
||||
|
||||
.. autoclass:: watcher.decision_engine.scoring.base.ScoringEngine
|
||||
:members:
|
||||
:special-members: __init__
|
||||
:noindex:

|
||||
|
||||
Abstract Plugin Container Class
|
||||
===============================
|
||||
|
||||
Here below is the abstract :py:class:`~.ScoringContainer` class:
|
||||
|
||||
.. autoclass:: watcher.decision_engine.scoring.base.ScoringEngineContainer
|
||||
:members:
|
||||
:special-members: __init__
|
||||
:noindex:
|
||||
|
||||
|
||||
.. _scoring_engine_plugin_add_entrypoint:
|
||||
|
||||
Add a new entry point
|
||||
=====================
|
||||
|
||||
In order for the Watcher Decision Engine to load your new scoring engine, it
|
||||
must be registered as a named entry point under the ``watcher_scoring_engines``
|
||||
entry point of your ``setup.py`` file. If you are using pbr_, this entry point
|
||||
should be placed in your ``setup.cfg`` file.
|
||||
|
||||
The name you give to your entry point has to be unique and should be the same
|
||||
as the value returned by the :py:meth:`~.ScoringEngine.get_name` method of your
|
||||
strategy.
|
||||
|
||||
Here below is how you would proceed to register ``NewScorer`` using pbr_:
|
||||
|
||||
.. code-block:: ini
|
||||
|
||||
[entry_points]
|
||||
watcher_scoring_engines =
|
||||
new_scorer = thirdparty.new:NewScorer
|
||||
|
||||
|
||||
To get a better understanding on how to implement a more advanced scoring
|
||||
engine, have a look at the :py:class:`~.DummyScorer` class. This implementation
|
||||
is not really using machine learning, but other than that it contains all the
|
||||
pieces which the "real" implementation would have.
|
||||
|
||||
In addition, for some use cases there is a need to register a list (possibly
|
||||
dynamic, depending on the implementation and configuration) of scoring engines
|
||||
in a single plugin, so there is no need to restart :ref:`Watcher Decision
|
||||
Engine <watcher_decision_engine_definition>` every time such list changes. For
|
||||
these cases, an additional ``watcher_scoring_engine_containers`` entry point
|
||||
can be used.
|
||||
|
||||
For the example how to use scoring engine containers, please have a look at
|
||||
the :py:class:`~.DummyScoringContainer` and the way it is configured in
|
||||
``setup.cfg``. For new containers it could be done like this:
|
||||
|
||||
.. code-block:: ini
|
||||
|
||||
[entry_points]
|
||||
watcher_scoring_engine_containers =
|
||||
new_scoring_container = thirdparty.new:NewContainer
|
||||
|
||||
.. _pbr: http://docs.openstack.org/developer/pbr/
|
||||
|
||||
|
||||
Using scoring engine plugins
|
||||
============================
|
||||
|
||||
The Watcher Decision Engine service will automatically discover any installed
|
||||
plugins when it is restarted. If a Python package containing a custom plugin is
|
||||
installed within the same environment as Watcher, Watcher will automatically
|
||||
make that plugin available for use.
|
||||
|
||||
At this point, Watcher will scan and register inside the :ref:`Watcher Database
|
||||
<watcher_database_definition>` all the scoring engines you implemented upon
|
||||
restarting the :ref:`Watcher Decision Engine
|
||||
<watcher_decision_engine_definition>`.
|
||||
|
||||
In addition, ``watcher-sync`` tool can be used to trigger :ref:`Watcher
|
||||
Database <watcher_database_definition>` synchronization. This might be used for
|
||||
"dynamic" scoring containers, which can return different scoring engines based
|
||||
on some external configuration (if they support that).

=================================

Build a new optimization strategy
|
||||
=================================
|
||||
|
||||
Watcher Decision Engine has an external :ref:`strategy <strategy_definition>`
|
||||
plugin interface which gives anyone the ability to integrate an external
|
||||
strategy in order to make use of placement algorithms.
|
||||
|
||||
This section gives some guidelines on how to implement and integrate custom
|
||||
strategies with Watcher. If you wish to create a third-party package for your
|
||||
plugin, you can refer to our :ref:`documentation for third-party package
|
||||
creation <plugin-base_setup>`.
|
||||
|
||||
|
||||
Pre-requisites
|
||||
==============
|
||||
|
||||
Before using any strategy, you should make sure you have your Telemetry service
|
||||
configured so that it would provide you all the metrics you need to be able to
|
||||
use your strategy.
|
||||
|
||||
|
||||
Create a new strategy plugin
|
||||
============================
|
||||
|
||||
In order to create a new strategy, you have to:
|
||||
|
||||
- Extend the :py:class:`~.UnclassifiedStrategy` class
|
||||
- Implement its :py:meth:`~.BaseStrategy.get_name` class method to return the
|
||||
**unique** ID of the new strategy you want to create. This unique ID should
|
||||
be the same as the name of :ref:`the entry point we will declare later on
|
||||
<strategy_plugin_add_entrypoint>`.
|
||||
- Implement its :py:meth:`~.BaseStrategy.get_display_name` class method to
|
||||
return the translated display name of the strategy you want to create.
|
||||
Note: Do not use a variable to return the translated string so it can be
|
||||
automatically collected by the translation tool.
|
||||
- Implement its :py:meth:`~.BaseStrategy.get_translatable_display_name`
|
||||
class method to return the translation key (actually the English display
|
||||
name) of your new strategy. The value return should be the same as the
|
||||
string translated in :py:meth:`~.BaseStrategy.get_display_name`.
|
||||
- Implement its :py:meth:`~.BaseStrategy.execute` method to return the
|
||||
solution you computed within your strategy.
|
||||
|
||||
Here is an example showing how you can write a plugin called ``NewStrategy``:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
# filepath: thirdparty/new.py
|
||||
# import path: thirdparty.new
|
||||
import abc
|
||||
|
||||
import six
|
||||
|
||||
from watcher._i18n import _
|
||||
from watcher.decision_engine.strategy.strategies import base
|
||||
|
||||
|
||||
class NewStrategy(base.UnclassifiedStrategy):
|
||||
|
||||
def __init__(self, osc=None):
|
||||
super(NewStrategy, self).__init__(osc)
|
||||
|
||||
def execute(self, original_model):
|
||||
self.solution.add_action(action_type="nop",
|
||||
input_parameters=parameters)
|
||||
# Do some more stuff here ...
|
||||
return self.solution
|
||||
|
||||
@classmethod
|
||||
def get_name(cls):
|
||||
return "new_strategy"
|
||||
|
||||
@classmethod
|
||||
def get_display_name(cls):
|
||||
return _("New strategy")
|
||||
|
||||
@classmethod
|
||||
def get_translatable_display_name(cls):
|
||||
return "New strategy"
|
||||
|
||||
|
||||
As you can see in the above example, the :py:meth:`~.BaseStrategy.execute`
|
||||
method returns a :py:class:`~.BaseSolution` instance as required. This solution
|
||||
is what wraps the abstract set of actions the strategy recommends to you. This
|
||||
solution is then processed by a :ref:`planner <watcher_planner_definition>` to
|
||||
produce an action plan which contains the sequenced flow of actions to be
|
||||
executed by the :ref:`Watcher Applier <watcher_applier_definition>`. This
|
||||
solution also contains the various :ref:`efficacy indicators
|
||||
<efficacy_indicator_definition>` alongside its computed :ref:`global efficacy
|
||||
<efficacy_definition>`.
|
||||
|
||||
Please note that your strategy class will expect to find the same constructor
|
||||
signature as BaseStrategy to instantiate you strategy. Therefore, you should
|
||||
ensure that your ``__init__`` signature is identical to the
|
||||
:py:class:`~.BaseStrategy` one.
|
||||
|
||||
|
||||
Strategy efficacy
|
||||
=================
|
||||
|
||||
As stated before, the ``NewStrategy`` class extends a class called
|
||||
:py:class:`~.UnclassifiedStrategy`. This class actually implements a set of
|
||||
abstract methods which are defined within the :py:class:`~.BaseStrategy` parent
|
||||
class.
|
||||
|
||||
One thing this :py:class:`~.UnclassifiedStrategy` class defines is that our
|
||||
``NewStrategy`` achieves the ``unclassified`` goal. This goal is a peculiar one
|
||||
as it does not contain any indicator nor does it calculate a global efficacy.
|
||||
This proves itself to be quite useful during the development of a new strategy
|
||||
for which the goal has yet to be defined or in case a :ref:`new goal
|
||||
<implement_goal_plugin>` has yet to be implemented.
|
||||
|
||||
|
||||
Define Strategy Parameters
|
||||
==========================
|
||||
|
||||
For each new added strategy, you can add parameters spec so that an operator
|
||||
can input strategy parameters when creating an audit to control the
|
||||
:py:meth:`~.BaseStrategy.execute` behavior of strategy. This is useful to
|
||||
define some threshold for your strategy, and tune them at runtime.
|
||||
|
||||
To define parameters, just implements :py:meth:`~.BaseStrategy.get_schema` to
|
||||
return parameters spec with `jsonschema
|
||||
<http://json-schema.org/>`_ format.
|
||||
It is strongly encouraged that provide default value for each parameter, or
|
||||
else reference fails if operator specify no parameters.
|
||||
|
||||
Here is an example showing how you can define 2 parameters for
|
||||
``DummyStrategy``:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
class DummyStrategy(base.DummyBaseStrategy):
|
||||
|
||||
@classmethod
|
||||
def get_schema(cls):
|
||||
return {
|
||||
"properties": {
|
||||
"para1": {
|
||||
"description": "number parameter example",
|
||||
"type": "number",
|
||||
"default": 3.2,
|
||||
"minimum": 1.0,
|
||||
"maximum": 10.2,
|
||||
},
|
||||
"para2": {
|
||||
"description": "string parameter example",
|
||||
"type": "string",
|
||||
"default": "hello",
|
||||
},
|
||||
},
|
||||
}
|
||||
|
||||
|
||||
You can reference parameters in :py:meth:`~.BaseStrategy.execute`:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
class DummyStrategy(base.DummyBaseStrategy):
|
||||
|
||||
def execute(self):
|
||||
para1 = self.input_parameters.para1
|
||||
para2 = self.input_parameters.para2
|
||||
|
||||
if para1 > 5:
|
||||
...
|
||||
|
||||
|
||||
Operator can specify parameters with following commands:
|
||||
|
||||
.. code:: bash
|
||||
|
||||
$ watcher audit create -a <your_audit_template> -p para1=6.0 -p para2=hi

.. _strategy_plugin_add_entrypoint:

|
||||
Add a new entry point
|
||||
=====================
|
||||
|
||||
In order for the Watcher Decision Engine to load your new strategy, the
|
||||
strategy must be registered as a named entry point under the
|
||||
``watcher_strategies`` entry point of your ``setup.py`` file. If you are using
|
||||
pbr_, this entry point should be placed in your ``setup.cfg`` file.
|
||||
|
||||
The name you give to your entry point has to be unique and should be the same
|
||||
as the value returned by the :py:meth:`~.BaseStrategy.get_name` class method of
|
||||
your strategy.
|
||||
|
||||
Here below is how you would proceed to register ``NewStrategy`` using pbr_:
|
||||
|
||||
.. code-block:: ini
|
||||
|
||||
[entry_points]
|
||||
watcher_strategies =
|
||||
new_strategy = thirdparty.new:NewStrategy
|
||||
|
||||
|
||||
To get a better understanding on how to implement a more advanced strategy,
|
||||
have a look at the :py:class:`~.BasicConsolidation` class.
|
||||
|
||||
.. _pbr: http://docs.openstack.org/developer/pbr/
|
||||
|
||||
Using strategy plugins
|
||||
======================
|
||||
|
||||
The Watcher Decision Engine service will automatically discover any installed
|
||||
plugins when it is restarted. If a Python package containing a custom plugin is
|
||||
installed within the same environment as Watcher, Watcher will automatically
|
||||
make that plugin available for use.
|
||||
|
||||
At this point, Watcher will scan and register inside the :ref:`Watcher Database
|
||||
<watcher_database_definition>` all the strategies (alongside the goals they
|
||||
should satisfy) you implemented upon restarting the :ref:`Watcher Decision
|
||||
Engine <watcher_decision_engine_definition>`.
|
||||
|
||||
You should take care when installing strategy plugins. By their very nature,
|
||||
there are no guarantees that utilizing them as is will be supported, as
|
||||
they may require a set of metrics which is not yet available within the
|
||||
Telemetry service. In such a case, please do make sure that you first
|
||||
check/configure the latter so your new strategy can be fully functional.
|
||||
|
||||
Querying metrics
|
||||
----------------
|
||||
|
||||
A large set of metrics, generated by OpenStack modules, can be used in your
|
||||
strategy implementation. To collect these metrics, Watcher provides a
|
||||
`Helper`_ for two data sources which are `Ceilometer`_ and `Monasca`_. If you
|
||||
wish to query metrics from a different data source, you can implement your own
|
||||
and directly use it from within your new strategy. Indeed, strategies in
|
||||
Watcher have the cluster data models decoupled from the data sources which
|
||||
means that you may keep the former while changing the latter.
|
||||
The recommended way for you to support a new data source is to implement a new
|
||||
helper that would encapsulate within separate methods the queries you need to
|
||||
perform. To then use it, you would just have to instantiate it within your
|
||||
strategy.
|
||||
|
||||
If you want to use Ceilometer but with your own metrics database backend,
|
||||
please refer to the `Ceilometer developer guide`_. The list of the available
|
||||
Ceilometer backends is located here_. The `Ceilosca`_ project is a good example
|
||||
of how to create your own pluggable backend. Moreover, if your strategy
|
||||
requires new metrics not covered by Ceilometer, you can add them through a
|
||||
`Ceilometer plugin`_.

Read usage metrics using the Watcher Datasource Helper
|
||||
------------------------------------------------------
|
||||
|
||||
The following code snippet shows how to invoke a Datasource Helper class:
|
||||
|
||||
.. code-block:: py
|
||||
|
||||
from watcher.datasource import ceilometer as ceil
|
||||
from watcher.datasource import monasca as mon
|
||||
|
||||
@property
|
||||
def ceilometer(self):
|
||||
if self._ceilometer is None:
|
||||
self._ceilometer = ceil.CeilometerHelper(osc=self.osc)
|
||||
return self._ceilometer
|
||||
|
||||
@property
|
||||
def monasca(self):
|
||||
if self._monasca is None:
|
||||
self._monasca = mon.MonascaHelper(osc=self.osc)
|
||||
return self._monasca
|
||||
|
||||
Using that you can now query the values for that specific metric:
|
||||
|
||||
.. code-block:: py
|
||||
|
||||
if self.config.datasource == "ceilometer":
|
||||
resource_id = "%s_%s" % (node.uuid, node.hostname)
|
||||
return self.ceilometer.statistic_aggregation(
|
||||
resource_id=resource_id,
|
||||
meter_name='compute.node.cpu.percent',
|
||||
period="7200",
|
||||
aggregate='avg',
|
||||
)
|
||||
elif self.config.datasource == "monasca":
|
||||
statistics = self.monasca.statistic_aggregation(
|
||||
meter_name='compute.node.cpu.percent',
|
||||
dimensions=dict(hostname=node.uuid),
|
||||
period=7200,
|
||||

Unit tests
|
||||
==========
|
||||
|
||||
All unit tests should be run using `tox`_. To run the same unit tests that are
|
||||
executing onto `Gerrit`_ which includes ``py35``, ``py27`` and ``pep8``, you
|
||||
can issue the following command::
|
||||
|
||||
$ workon watcher
|
||||
(watcher) $ pip install tox
|
||||
(watcher) $ cd watcher
|
||||
(watcher) $ tox
|
||||
|
||||
If you want to only run one of the aforementioned, you can then issue one of
|
||||
the following::
|
||||
|
||||
$ workon watcher
|
||||
(watcher) $ tox -e py35
|
||||
(watcher) $ tox -e py27
|
||||
(watcher) $ tox -e pep8
|
||||
|
||||
.. _tox: https://tox.readthedocs.org/
|
||||
.. _Gerrit: http://review.openstack.org/
|
||||
|
||||
You may pass options to the test programs using positional arguments. To run a
|
||||
specific unit test, you can pass extra options to `os-testr`_ after putting
|
||||
the ``--`` separator. So using the ``-r`` option followed by a regex string,
|
||||
you can run the desired test::
|
||||
|
||||
$ workon watcher
|
||||
(watcher) $ tox -e py27 -- -r watcher.tests.api
|
||||
|
||||
.. _os-testr: http://docs.openstack.org/developer/os-testr/
|
||||
|
||||
When you're done, deactivate the virtualenv::

||||
$ deactivate

Administrator
|
||||
=============
|
||||
|
||||
The :ref:`Administrator <administrator_definition>` is any user who has admin
|
||||
access on the OpenStack cluster. This user is allowed to create new projects
|
||||
for tenants, create new users and assign roles to each user.
|
||||
|
||||
The :ref:`Administrator <administrator_definition>` usually has remote access
|
||||
to any host of the cluster in order to change the configuration and restart any
|
||||
OpenStack service, including Watcher.
|
||||
|
||||
In the context of Watcher, the :ref:`Administrator <administrator_definition>`
|
||||
is a role for users which allows them to run any Watcher commands, such as:
|
||||
|
||||
- Create/Delete an :ref:`Audit Template <audit_template_definition>`
|
||||
- Launch an :ref:`Audit <audit_definition>`
|
||||
- Get the :ref:`Action Plan <action_plan_definition>`
|
||||
- Launch a recommended :ref:`Action Plan <action_plan_definition>` manually
|
||||
- Archive previous :ref:`Audits <audit_definition>` and
|
||||
:ref:`Action Plans <action_plan_definition>`
|
||||
|
||||
|
||||
The :ref:`Administrator <administrator_definition>` is also allowed to modify
|
||||
any Watcher configuration files and to restart Watcher services.

Cluster
|
||||
=======
|
||||
|
||||
A :ref:`Cluster <cluster_definition>` is a set of physical machines which
|
||||
provide compute, storage and networking resources and are managed by the same
|
||||
OpenStack Controller node.
|
||||
A :ref:`Cluster <cluster_definition>` represents a set of resources that a
|
||||
cloud provider is able to offer to his/her
|
||||
:ref:`customers <customer_definition>`.
|
||||
|
||||
A data center may contain several clusters.
|
||||
|
||||
The :ref:`Cluster <cluster_definition>` may be divided in one or several
|
||||
:ref:`Availability Zone(s) <availability_zone_definition>`.

|
||||
.. _controller_node_definition:
|
||||
|
||||
Controller Node
|
||||
===============
|
||||
|
||||
A controller node is a machine that typically runs the following core OpenStack
|
||||
services:
|
||||
|
||||
- Keystone: for identity and service management
|
||||
- Cinder scheduler: for volumes management
|
||||
- Glance controller: for image management
|
||||
- Neutron controller: for network management
|
||||
- Nova controller: for global compute resources management with services
|
||||
such as nova-scheduler, nova-conductor and nova-network.
|
||||
|
||||
In many configurations, Watcher will reside on a controller node even if it
|
||||
can potentially be hosted on a dedicated machine.
|
||||
|
||||
.. _compute_node_definition:
|
||||

||||
<http://docs.openstack.org/ops-guide/arch-compute-nodes.html>`_.
|
||||
|
||||
.. _customer_definition:
|
||||
|
||||
Customer
|
||||
========
|
||||
|
||||
A :ref:`Customer <customer_definition>` is the person or company which
|
||||
subscribes to the cloud provider offering. A customer may have several
|
||||
:ref:`Project(s) <project_definition>`
|
||||
hosted on the same :ref:`Cluster <cluster_definition>` or dispatched on
|
||||
different clusters.
|
||||
|
||||
In the private cloud context, the :ref:`Customers <customer_definition>` are
|
||||
different groups within the same organization (different departments, project
|
||||
teams, branch offices and so on). Cloud infrastructure includes the ability to
|
||||
precisely track each customer's service usage so that it can be charged back to
|
||||
them, or at least reported to them.
|
||||
|
||||

|
||||
<http://docs.openstack.org/developer/nova/aggregates.html>`_.
|
||||
|
||||
.. _instance_definition:
|
||||
|
||||
Instance
|
||||
========
|
||||
|
||||
A running virtual machine, or a virtual machine in a known state such as
|
||||
suspended, that can be used like a hardware server.
|
||||
|
||||
.. _managed_resource_definition:
|
||||
|
||||
Managed resource
|
||||
================
|
||||
|
||||
A :ref:`Managed resource <managed_resource_definition>` is one instance of
|
||||
:ref:`Managed resource type <managed_resource_type_definition>` in a topology
|
||||
with particular properties and dependencies on other
|
||||
:ref:`Managed resources <managed_resource_definition>` (relationships).
|
||||
|
||||
For example, a :ref:`Managed resource <managed_resource_definition>` can be one
|
||||
virtual machine (i.e., an :ref:`instance <instance_definition>`) hosted on a
|
||||
:ref:`compute node <compute_node_definition>` and connected to another virtual
|
||||
machine through a network link (represented also as a
|
||||
:ref:`Managed resource <managed_resource_definition>` in the
|
||||
:ref:`Cluster Data Model <cluster_data_model_definition>`).
|
||||
|
||||
.. _managed_resource_type_definition:
|
||||
|
||||
Managed resource type
|
||||
=====================
|
||||
|
||||
A :ref:`Managed resource type <managed_resource_definition>` is a type of
|
||||
hardware or software element of the :ref:`Cluster <cluster_definition>` that
|
||||
the Watcher system can act on.
|
||||
|
||||
Here are some examples of
|
||||
:ref:`Managed resource types <managed_resource_definition>`:
|
||||
|
||||
- `Nova Host Aggregates <http://docs.openstack.org/developer/heat/template_guide/openstack.html#OS::Nova::HostAggregate>`_

|
||||
|
||||
Efficacy Indicator
|
||||
==================
|
||||
|
||||
.. watcher-term:: watcher.api.controllers.v1.efficacy_indicator
|
||||
|
||||
.. _efficacy_specification_definition:
|
||||
|
||||
Efficacy Specification
|
||||
======================
|
||||
|
||||
.. watcher-term:: watcher.decision_engine.goal.efficacy.base
|
||||
|
||||
.. _efficacy_definition:
|
||||
|
||||
Optimization Efficacy
|
||||
=====================
|
||||
|
||||
The :ref:`Optimization Efficacy <efficacy_definition>` is the objective
|
||||
measure of how much of the :ref:`Goal <goal_definition>` has been achieved in
|
||||
respect with constraints and :ref:`SLAs <sla_definition>` defined by the
|
||||
:ref:`Customer <customer_definition>`.
|
||||
|
||||
The way efficacy is evaluated will depend on the :ref:`Goal <goal_definition>`
|
||||
to achieve.
|
||||
|
||||
Of course, the efficacy will be relevant only as long as the
|
||||
:ref:`Action Plan <action_plan_definition>` is relevant
|
||||
(i.e., the current state of the :ref:`Cluster <cluster_definition>`
|
||||
has not changed in a way that a new :ref:`Audit <audit_definition>` would need
|
||||
to be launched).
|
||||
|
||||
For example, if the :ref:`Goal <goal_definition>` is to lower the energy
|
||||
consumption, the :ref:`Efficacy <efficacy_definition>` will be computed
|
||||
using several :ref:`efficacy indicators <efficacy_indicator_definition>`
|
||||
(KPIs):
|
||||
|
||||
- the percentage of energy gain (which must be the highest possible)
|
||||
- the number of :ref:`SLA violations <sla_violation_definition>`
|
||||
(which must be the lowest possible)
|
||||
- the number of virtual machine migrations (which must be the lowest possible)
|
||||
|
||||
All those indicators are computed within a given timeframe, which is the
|
||||
time taken to execute the whole :ref:`Action Plan <action_plan_definition>`.
|
||||
|
||||
The efficacy also enables the :ref:`Administrator <administrator_definition>`
|
||||
to objectively compare different :ref:`Strategies <strategy_definition>` for
|
||||
the same goal and same workload of the :ref:`Cluster <cluster_definition>`.
|
||||
|
||||
.. _project_definition:
|
||||
|
||||
Project
|
||||
=======
|
||||
|
||||
:ref:`Projects <project_definition>` represent the base unit of “ownership”
|
||||
in OpenStack, in that all :ref:`resources <managed_resource_definition>` in
|
||||
OpenStack should be owned by a specific :ref:`project <project_definition>`.
|
||||
In OpenStack Identity, a :ref:`project <project_definition>` must be owned by a
|
||||
specific domain.
|
||||
|
||||
Please, read `the official OpenStack definition of a Project
|
||||
<http://docs.openstack.org/glossary/content/glossary.html>`_.

.. watcher-term:: watcher.api.controllers.v1.scoring_engine
|
||||
|
||||
.. _sla_definition:
|
||||
|
||||
SLA
|
||||
===
|
||||
|
||||
:ref:`SLA <sla_definition>` means Service Level Agreement.
|
||||
|
||||
The resources are negotiated between the :ref:`Customer <customer_definition>`
|
||||
and the Cloud Provider in a contract.
|
||||
|
||||
Most of the time, this contract is composed of two documents:
|
||||
|
||||
- :ref:`SLA <sla_definition>` : Service Level Agreement
|
||||
- :ref:`SLO <slo_definition>` : Service Level Objectives
|
||||
|
||||
Note that the :ref:`SLA <sla_definition>` is more general than the
|
||||
:ref:`SLO <slo_definition>` in the sense that the former specifies what service
|
||||
is to be provided, how it is supported, times, locations, costs, performance,
|
||||
and responsibilities of the parties involved while the
|
||||
:ref:`SLO <slo_definition>` focuses on more measurable characteristics such as
|
||||
availability, throughput, frequency, response time or quality.
|
||||
|
||||
You can also read `the Wikipedia page for SLA <https://en.wikipedia.org/wiki/Service-level_agreement>`_
|
||||
which provides a good definition.
|
||||
|
||||
.. _sla_violation_definition:
|
||||
|
||||
SLA violation
|
||||
=============
|
||||
|
||||
A :ref:`SLA violation <sla_violation_definition>` happens when a
|
||||
:ref:`SLA <sla_definition>` defined with a given
|
||||
:ref:`Customer <customer_definition>` could not be respected by the
|
||||
cloud provider within the timeframe defined by the official contract document.
|
||||
|
||||
.. _slo_definition:
|
||||
|
||||
SLO
|
||||
===
|
||||
|
||||
A Service Level Objective (SLO) is a key element of a
|
||||
:ref:`SLA <sla_definition>` between a service provider and a
|
||||
:ref:`Customer <customer_definition>`. SLOs are agreed as a means of measuring
|
||||
the performance of the Service Provider and are outlined as a way of avoiding
|
||||
disputes between the two parties based on misunderstanding.
|
||||
|
||||
You can also read `the Wikipedia page for SLO <https://en.wikipedia.org/wiki/Service_level_objective>`_

Welcome to Watcher documentation
|
||||
================================
|
||||
|
||||
OpenStack Watcher provides a flexible and scalable resource optimization
|
||||
service for multi-tenant OpenStack-based clouds.
|
||||
Watcher provides a complete optimization loop—including everything from a
|
||||
metrics receiver, complex event processor and profiler, optimization processor
|
||||
and an action plan applier. This provides a robust framework to realize a wide
|
||||
range of cloud optimization goals, including the reduction of data center
|
||||
operating costs, increased system performance via intelligent virtual machine
|
||||
migration, increased energy efficiency—and more!
|
||||
|
||||
Watcher project consists of several source code repositories:
|
||||
|
||||
* `watcher`_ - is the main repository. It contains code for Watcher API server,
|
||||
Watcher Decision Engine and Watcher Applier.
|
||||
* `python-watcherclient`_ - Client library and CLI client for Watcher.
|
||||
* `watcher-dashboard`_ - Watcher Horizon plugin.
|
||||
|
||||
The documentation provided here is continually kept up-to-date based
|
||||
on the latest code, and may not represent the state of the project at any
|
||||
specific prior release.
