Feature Overview

Notifications created by the Nova service contain a nova_object.version parameter with a value aligned within the current Nova service release. (See https://docs.openstack.org/nova/latest/reference/notifications.html#existing-versioned-notifications for more information about the currently available notification events and their payload construction.)

Ceilometer currently does not support versioned event payloads. The goal of this feature is to result in Ceilometer being expanded into accepting the updated event notification payload structure.

The upstream tracker for this effort is at https://bugs.launchpad.net/ceilometer/+bug/1665449 

Goals

Extend Ceilometer to accept the current Nova event notification payload structure, which contains a versioned payload system. Curerntly Ceilometer only accepts the unversioned structure, which will be removed and no longer available. By implementing this structure support Ceilometer will be able to maintain the ability to accept Nova event notifications.
