Add new notifications types for volumes/snapshots¶
Now we have only two types of notifications about volumes/snapshots: volume/snapshot existence and their size. This change allows to collect and view notifications of different types. We can get information about which events have occurred: volume/snapshot has been created or deleted or updated(renamed or modified description), volume has been resized or attached/detached. This will allow to process additional events and will improve the overall Ceilometer functionality.
Problem description¶
Now we have only two types of notifications about volumes/snapshots: volume/snapshot existence and their size. But there is no information about events like volume/snapshot was created or deleted or updated or volume was resized or attached/detached.
Proposed change¶
This change allows to collect and view notifications of different types - volume/snapshot.create.start, volume/snapshot.create.end, volume/snapshot.delete.start, volume/snapshot.delete.end, volume/snapshot.update.start, volume/snapshot.update.end, volume.resize.start, volume.resize.end, volume.attach.start, volume.attach.end, volume.detach.start, volume.detach.end.
