Get Aodh Alarms From Message Bus Notifications
|
|
==============================================
|
|
|
|
Get Aodh alarms immediately via notification from the message bus.
|
|
|
|
Problem description
|
|
===================
|
|
|
|
Currently Aodh datasource queries Aodh alarms periodically. It is not in time
|
|
and it is also not efficient, since most query will get no change when the
|
|
interval of alarm evaluation in Aodh is larger than the interval of pulling
|
|
Aodh alarm in Vitrage.
|
|
|
|
Proposed change
|
|
===============
|
|
|
|
Aodh `update_method` in vitrage config file will be configured with:
|
|
|
|
/etc/vitrage/vitrage.conf
|
|
::
|
|
|
|
[aodh]
|
|
update_method = push
|
|
|
|
Add a new notification topic in Aodh config file:
|
|
|
|
/etc/aodh/aodh.conf
|
|
::
|
|
|
|
[oslo_messaging_notifications]
|
|
topics = vitrage_notifications
|
|
|
|
Vitrage listener will get the alarm events from the message bus. Aodh driver
|
|
will filter the needed event types, enrich the events and then send them to
|
|
the queue for the Aodh transformer to create, update or delete the entity
|
|
vertex.
