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.
