Configure Nova Notifications
============================
Watcher can consume notifications generated by the Nova services, in order to
build or update, in real time, its cluster data model related to computing
resources.
Nova publishes, by default, notifications on ``notifications`` AMQP queue
(configurable) and ``versioned_notifications`` AMQP queue (not
configurable). ``notifications`` queue is mainly used by ceilometer, so we can
not use it. And some events, related to nova-compute service state, are only
sent into the ``versioned_notifications`` queue.
By default, Watcher listens to AMQP queues named ``watcher_notifications``
and ``versioned_notifications``. So you have to update the Nova
configuration file on controller and compute nodes, in order
to Watcher receives Nova notifications in ``watcher_notifications`` as well.
* In the file ``/etc/nova/nova.conf``, update the section
``[oslo_messaging_notifications]``, by redefining the list of topics
into which Nova services will publish events ::
[oslo_messaging_notifications]
driver = messaging
topics = notifications,watcher_notifications
* Restart the Nova services.
