|
|
|
|
|
|
Installation
|
|
------------
|
|
|
|
Copy the 'https://raw.githubusercontent.com/openstack/vitrage/master/vitrage/datasources/kapacitor/auxiliary/kapacitor_vitrage.py' script into the Kapacitor servers.
|
|
|
|
.. code-block:: bash
|
|
|
|
$ cp kapacitor_vitrage.py /etc/kapacitor/kapacitor_vitrage.py
|
|
$ chmod 755 /etc/kapacitor/kapacitor_vitrage.py
|
|
|
|
|
|
Configuration
|
|
-------------
|
|
|
|
|
|
|
|
1. Define topic , which use for alert publish to. Create file ``forward_to_vitrage.yaml``:
|
|
|
|
|
|
| topic: forward_to_vitrage
|
|
| id: forward_to_vitrage
|
|
| kind: exec
|
|
| options:
|
|
| prog: '/usr/bin/python'
|
|
| args: ['/etc/kapacitor/kapacitor_vitrage.py','rabbit://<rabbit_user>:<rabbit_pass>@controller']
|
|
|
|
**Note:** rabbit://<rabbit_user>:<rabbit_pass>@controller is Vitrage message bus url, ``rabbit_user:rabbit_pass`` for devstack rabbitmq is ``stackrabbit/secret``
|
|
|
|
Run command to define topic
|
|
|
|
.. code:: bash
|
|
|
|
$ kapacitor define-topic-handler ./forward_to_vitrage.yaml
|
|
|
|
2. Assign your Task to topic, in Tick script define that alert, add in "alert()" step:
|
|
|
|
| ...
|
|
| alert()
|
|
| ...
|
|
| .topic('forward_to_vitrage')
|
|
|
|
In case your Task already in topic and you don't want to add another, you only need to do: append 'exec handler' to TICK script which define it.
|
|
|
|
| ...
|
|
| alert()
|
|
| ...
|
|
| .exec('/usr/bin/python', '/etc/kapacitor/kapacitor_vitrage.py', 'rabbit://<rabbit_user>:<rabbit_pass>@controller')
|
|
|
|
Run command define your task:
|
|
|
|
.. code::
|
|
|
|
$ kapacitor define <task_name> -tick <tick_script>
|
|
|
|
Vitrage configuration:
|
|
|
|
1. Add kapacitor to list of datasources in ``/etc/vitrage/vitrage.conf``
|
|
|
|
.. code::
|
|
|
|
[datasources]
|
|
types = kapacitor,zabbix,nova.host,nova.instance,nova.zone,static_physical,aodh,cinder.volume,neutron.network,neutron.port,heat.stack
|
|
|
|
2. Add section to ``/etc/vitrage/vitrage.conf``
|
|
|
|
.. code::
|
|
|
|
[kapacitor]
|
|
config_file = /etc/vitrage/kapacitor_conf.yaml
|
|
|
|
3. Create ``/etc/vitrage/kapacitor_conf.yaml`` with this content
|
|
|
|
.. code ::
|
|
|
|
kapacitor:
|
|
- alert:
|
|
host: cloud.compute1 # hostname of host been raised alarm
|
|
vitrage_resource:
|
|
type: nova.host # resource type of enity vitrage
|
|
name: compute-1 # resource name of enity vitrage
|
|
- alert:
|
|
host: compute-(.*)
|
|
vitrage_resource:
|
|
type: nova.host
|
|
name: ${kapacitor_host}
|
|
- alert:
|
|
host: (.*)
|
|
vitrage_resource:
|
|
type: nova.instance
|
|
name: ${kapacitor_host}
|
|
|
|
In example:
|
|
alarm on host have hostname `cloud.compute1` will map to resource name `compute-1`,
|
|
|
|
alarm on host have hostname `compute-99` will map to resource name `compute-99`
|
|
|
|
Another alarm, like alarm on instance will map with resource type ``nova.instance`` and name equal with hostname of instance
|
|
|
|
4. Restart vitrage service in devstack/openstack
|
|
|
|
