Audit using Aodh alarm
|
||||
======================
|
||||
|
||||
Audit with EVENT type can be triggered by special alarm. This guide walks
|
||||
you through the steps to build an event-driven optimization solution by
|
||||
integrating Watcher with Ceilometer/Aodh.
|
||||
|
||||
Step 1: Create an audit with EVENT type
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The first step is to create an audit with EVENT type,
|
||||
you can create an audit template firstly:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ openstack optimize audittemplate create your_template_name <your_goal> \
|
||||
--strategy <your_strategy>
|
||||
|
||||
or create an audit directly with special goal and strategy:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ openstack optimize audit create --goal <your_goal> \
|
||||
--strategy <your_strategy> --audit_type EVENT
|
||||
|
||||
This is an example for creating an audit with dummy strategy:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ openstack optimize audit create --goal dummy \
|
||||
--strategy dummy --audit_type EVENT

|
||||
|
||||
We need to build Aodh action url using Watcher webhook API.
|
||||
For convenience we export the url into an environment variable:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ export AUDIT_UUID=a3326a6a-c18e-4e8e-adba-d0c61ad404c5
|
||||
$ export ALARM_URL="trust+http://localhost/infra-optim/v1/webhooks/$AUDIT_UUID"
|
||||
|
||||
Step 2: Create Aodh Alarm
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Once we have the audit created, we can continue to create Aodh alarm and
|
||||
set the alarm action to Watcher webhook API. The alarm type can be event(
|
||||
i.e. ``compute.instance.create.end``) or gnocchi_resources_threshold(i.e.
|
||||
``cpu_util``), more info refer to alarm-creation_
|
||||
|
||||
For example:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ openstack alarm create \
|
||||
--type event --name instance_create \
|
||||
--event-type "compute.instance.create.end" \
|
||||
--enable True --repeat-actions False \
|
||||
--alarm-action $ALARM_URL

|
||||
|
||||
Step 3: Trigger the alarm
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
In this example, you can create a new instance to trigger the alarm.
|
||||
The alarm state will translate from ``insufficient data`` to ``alarm``.
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ openstack alarm show b9e381fc-8e3e-4943-82ee-647e7a2ef644
|
||||

|

|

|
||||

|
||||
|
||||
Step 4: Verify the audit
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
This can be verified to check if the audit state was ``SUCCEEDED``:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ openstack optimize audit show a3326a6a-c18e-4e8e-adba-d0c61ad404c5
|
||||
+---------------+--------------------------------------+
|
||||
| Field | Value |
|
||||
+---------------+--------------------------------------+
|
||||
| UUID | a3326a6a-c18e-4e8e-adba-d0c61ad404c5 |
|
||||
| Name | dummy-2020-01-14T03:21:19.168467 |
|
||||
| Created At | 2020-01-14T03:21:19+00:00 |
|
||||
| Updated At | 2020-01-14T06:26:40+00:00 |
|
||||
| Deleted At | None |
|
||||
| State | SUCCEEDED |
|
||||
| Audit Type | EVENT |
|
||||
| Parameters | {u'para2': u'hello', u'para1': 3.2} |
|
||||
| Interval | None |
|
||||
| Goal | dummy |
|
||||
| Strategy | dummy |
|
||||
| Audit Scope | [] |
|
||||
| Auto Trigger | False |
|
||||
| Next Run Time | None |
|
||||
| Hostname | ubuntudbs |
|
||||
| Start Time | None |
|
||||
| End Time | None |
|
||||
| Force | False |
|
||||
+---------------+--------------------------------------+
|
||||
|
||||
and you can use the following command to check if the action plan
|
||||
was created:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ openstack optimize actionplan list --audit a3326a6a-c18e-4e8e-adba-d0c61ad404c5
|
||||
