Configure Cinder Notifications
==============================
Watcher can also consume notifications generated by the Cinder services, in
order to build or update, in real time, its cluster data model related to
storage resources. To do so, you have to update the Cinder configuration
file on controller and volume nodes, in order to let Watcher receive Cinder
notifications in a dedicated ``watcher_notifications`` channel.
* In the file ``/etc/cinder/cinder.conf``, update the section
``[oslo_messaging_notifications]``, by redefining the list of topics
into which Cinder services will publish events ::
[oslo_messaging_notifications]
driver = messagingv2
topics = notifications,watcher_notifications
* Restart the Cinder services.
