=====================
Installing Manually
=====================
Storage Backend Installation
============================
This step is a prerequisite for the collector and API services. You may use
one of the listed database backends below to store Ceilometer data.
Gnocchi
-------
1. Follow `Gnocchi installation`_ instructions
2. Initialize Gnocchi for Ceilometer::
$ gnocchi-upgrade --create-legacy-resource-types
.. note::
Prior to Gnocchi 2.1, Ceilometer resource types were included, therefore
--create-legacy-resource-types flag is not needed.
3. Edit `/etc/ceilometer/ceilometer.conf` for the collector service::
[DEFAULT]
meter_dispatchers = gnocchi
event_dispatchers = gnocchi
[dispatcher_gnocchi]
filter_service_activity = False # Enable if using swift backend
filter_project = <project name associated with gnocchi user> # if using swift backend
[service_credentials]
auth_url = <auth_url>:5000
region_name = RegionOne
password = password
username = ceilometer
project_name = service
project_domain_id = default
user_domain_id = default
auth_type = password
4. Copy gnocchi_resources.yaml to config directory (e.g./etc/ceilometer)
5. To minimize data requests, caching and batch processing should be enabled:
1. Enable resource caching (oslo.cache_ should be installed)::
[cache]
backend_argument = redis_expiration_time:600
backend_argument = db:0
backend_argument = distributed_lock:True
backend_argument = url:redis://localhost:6379
backend = dogpile.cache.redis
2. Enable batch processing::
[collector]
batch_size = 100
batch_timeout = 5
6. Start collector service
.. _oslo.cache: http://docs.openstack.org/developer/oslo.cache/opts.html
MongoDB
-------
Follow the instructions to install the MongoDB_ package for your operating
system, then start the service. The required minimum version of MongoDB is
2.4.x. You will also need to have pymongo_ 2.4 installed
To use MongoDB as the storage backend, change the 'database' section in
ceilometer.conf as follows::
[database]
connection = mongodb://username:password@host:27017/ceilometer
SQLalchemy-supported DBs
------------------------
You may alternatively use any SQLAlchemy-supported DB such as
`PostgreSQL` or `MySQL`.
To use MySQL as the storage backend, change the 'database' section in
ceilometer.conf as follows::
[database]
connection = mysql+pymysql://username:password@host/ceilometer?charset=utf8
HBase
-----
HBase backend is implemented to use HBase Thrift interface, therefore it is
mandatory to have the HBase Thrift server installed and running. To start
the Thrift server, please run the following command::
${HBASE_HOME}/bin/hbase thrift start
The implementation uses `HappyBase`_, which is a wrapper library used to
interact with HBase via Thrift protocol. You can verify the Thrift
connection by running a quick test from a client:
.. code-block:: python
import happybase
conn = happybase.Connection(host=$hbase-thrift-server,
port=9090,
table_prefix=None,
table_prefix_separator='_')
print conn.tables() # this returns a list of HBase tables in your HBase server
.. note::
HappyBase version 0.5 or greater is required. Additionally, version 0.7
is not currently supported.
In the case of HBase, the required database tables (`project`, `user`, `resource`,
`meter`) should be created manually with `f` column family for each one.
To use HBase as the storage backend, change the 'database' section in
ceilometer.conf as follows::
[database]
connection = hbase://hbase-thrift-host:9090
It is possible to customize happybase's `table_prefix` and `table_prefix_separator`
via query string. By default `table_prefix` is not set and `table_prefix_separator`
is '_'. When `table_prefix` is not specified `table_prefix_separator` is not taken
into account. E.g. the resource table in the default case will be 'resource' while
with `table_prefix` set to 'ceilo' and `table_prefix_separator` to '.' the resulting
table will be 'ceilo.resource'. For this second case this is the database connection
configuration::
[database]
connection = hbase://hbase-thrift-host:9090?table_prefix=ceilo&table_prefix_separator=.
To ensure proper configuration, please add the following lines to the
`hbase-site.xml` configuration file::
<property>
<name>hbase.thrift.minWorkerThreads</name>
<value>200</value>
</property>

Installing the notification agent
=================================
.. index::
double: installing; agent-notification
1. Clone the ceilometer git repository to the management server::
$ cd /opt/stack
$ git clone https://git.openstack.org/openstack/ceilometer.git
2. As a user with ``root`` permissions or ``sudo`` privileges, run the
ceilometer installer::
$ cd ceilometer
$ sudo python setup.py install
3. Copy the sample configuration files from the source tree
to their final location::
$ mkdir -p /etc/ceilometer
$ cp etc/ceilometer/*.json /etc/ceilometer
$ cp etc/ceilometer/*.yaml /etc/ceilometer
$ cp etc/ceilometer/ceilometer.conf.sample /etc/ceilometer/ceilometer.conf
4. Edit ``/etc/ceilometer/ceilometer.conf``
1. Configure messaging::
[oslo_messaging_notifications]
topics = notifications
[oslo_messaging_rabbit]
rabbit_userid = stackrabbit
rabbit_password = openstack1
rabbit_hosts = 10.0.2.15
2. Set the ``telemetry_secret`` value.
Set the ``telemetry_secret`` value to a large, random, value. Use
the same value in all ceilometer configuration files, on all
nodes, so that messages passing between the nodes can be
validated. This value can be left empty to disable message signing.
.. note::
Disabling signing will improve message handling performance
Refer to :doc:`/configuration` for details about any other options
you might want to modify before starting the service.
5. Start the notification daemon::
$ ceilometer-agent-notification
.. note::
The default development configuration of the collector logs to
stderr, so you may want to run this step using a screen session
or other tool for maintaining a long-running program in the
background.
Installing the collector
========================
.. index::
double: installing; collector
.. _storage_backends:
1. Clone the ceilometer git repository to the management server::
$ cd /opt/stack
$ git clone https://git.openstack.org/openstack/ceilometer.git
2. As a user with ``root`` permissions or ``sudo`` privileges, run the
ceilometer installer::
$ cd ceilometer
$ sudo python setup.py install
3. Copy the sample configuration files from the source tree
to their final location::
$ mkdir -p /etc/ceilometer
$ cp etc/ceilometer/*.json /etc/ceilometer
$ cp etc/ceilometer/*.yaml /etc/ceilometer
$ cp etc/ceilometer/ceilometer.conf.sample /etc/ceilometer/ceilometer.conf
4. Edit ``/etc/ceilometer/ceilometer.conf``
1. Configure messaging::
[oslo_messaging_notifications]
topics = notifications
[oslo_messaging_rabbit]
rabbit_userid = stackrabbit
rabbit_password = openstack1
rabbit_hosts = 10.0.2.15
2. Set the ``telemetry_secret`` value (if enabled for notification agent)
Refer to :doc:`/configuration` for details about any other options
you might want to modify before starting the service.
5. Start the collector::
$ ceilometer-collector
.. note::
The default development configuration of the collector logs to
stderr, so you may want to run this step using a screen session
or other tool for maintaining a long-running program in the
background.
Installing the Polling Agent
============================
.. index::
double: installing; agent
.. note::
The polling agent needs to be able to talk to Keystone and any of
the services being polled for updates. It also needs to run on your compute
nodes to poll instances.
1. Clone the ceilometer git repository to the server::
$ cd /opt/stack
$ git clone https://git.openstack.org/openstack/ceilometer.git
2. As a user with ``root`` permissions or ``sudo`` privileges, run the
ceilometer installer::
$ cd ceilometer
$ sudo python setup.py install
3. Copy the sample configuration files from the source tree
to their final location::
$ mkdir -p /etc/ceilometer
$ cp etc/ceilometer/*.json /etc/ceilometer
$ cp etc/ceilometer/*.yaml /etc/ceilometer
$ cp etc/ceilometer/ceilometer.conf.sample /etc/ceilometer/ceilometer.conf
4. Configure messaging by editing ``/etc/ceilometer/ceilometer.conf``::
[oslo_messaging_notifications]
topics = notifications
[oslo_messaging_rabbit]
rabbit_userid = stackrabbit
rabbit_password = openstack1
rabbit_hosts = 10.0.2.15
5. In order to retrieve object store statistics, ceilometer needs
access to swift with ``ResellerAdmin`` role. You should give this
role to your ``os_username`` user for tenant ``os_tenant_name``::
$ openstack role create ResellerAdmin
+-----------+----------------------------------+
| Field | Value |
+-----------+----------------------------------+
| domain_id | None |
| id | f5153dae801244e8bb4948f0a6fb73b7 |
| name | ResellerAdmin |
+-----------+----------------------------------+
$ openstack role add f5153dae801244e8bb4948f0a6fb73b7 \
--project $SERVICE_TENANT \
--user $CEILOMETER_USER
6. Start the agent::
$ ceilometer-polling
7. By default, the polling agent polls the `compute` and `central` namespaces.
You can specify which namespace to poll in the `ceilometer.conf`
configuration file or on the command line::
$ ceilometer-polling --polling-namespaces central,ipmi
Installing the API Server
=========================
.. index::
double: installing; API
.. note::
The API server needs to be able to talk to keystone and ceilometer's
database. It is only required if you choose to store data in legacy
database or if you inject new samples via REST API.
1. Clone the ceilometer git repository to the server::
$ cd /opt/stack
$ git clone https://git.openstack.org/openstack/ceilometer.git
2. As a user with ``root`` permissions or ``sudo`` privileges, run the
ceilometer installer::
$ cd ceilometer
$ sudo python setup.py install
3. Copy the sample configuration files from the source tree
to their final location::
$ mkdir -p /etc/ceilometer
$ cp etc/ceilometer/api_paste.ini /etc/ceilometer
$ cp etc/ceilometer/*.json /etc/ceilometer
$ cp etc/ceilometer/*.yaml /etc/ceilometer
$ cp etc/ceilometer/ceilometer.conf.sample /etc/ceilometer/ceilometer.conf
4. Configure messaging by editing ``/etc/ceilometer/ceilometer.conf``::
[oslo_messaging_notifications]
topics = notifications
[oslo_messaging_rabbit]
rabbit_userid = stackrabbit
rabbit_password = openstack1
rabbit_hosts = 10.0.2.15
5. Create a service for ceilometer in keystone::
$ openstack service create metering --name=ceilometer \
--description="Ceilometer Service"
6. Create an endpoint in keystone for ceilometer::
$ openstack endpoint create $CEILOMETER_SERVICE \
--region RegionOne \
--publicurl "http://$SERVICE_HOST:8777" \
--adminurl "http://$SERVICE_HOST:8777" \
--internalurl "http://$SERVICE_HOST:8777"
.. note::
CEILOMETER_SERVICE is the id of the service created by the first command
and SERVICE_HOST is the host where the Ceilometer API is running. The
default port value for ceilometer API is 8777. If the port value
has been customized, adjust accordingly.
7. Choose and start the API server.
Ceilometer includes the ``ceilometer-api`` command. This can be
used to run the API server. For smaller or proof-of-concept
installations this is a reasonable choice. For larger installations it
is strongly recommended to install the API server in a WSGI host
such as mod_wsgi (see :doc:`mod_wsgi`). Doing so will provide better
performance and more options for making adjustments specific to the
installation environment.
If you are using the ``ceilometer-api`` command it can be started
as::
$ ceilometer-api
.. note::
The development version of the API server logs to stderr, so you
may want to run this step using a screen session or other tool for
maintaining a long-running program in the background.
