Notifications
|
|
-------------
|
|
|
|
The Bare Metal service supports the emission of notifications, which are
|
|
messages sent on a message broker (like RabbitMQ or anything else supported by
|
|
the `oslo messaging library
|
|
<https://docs.openstack.org/oslo.messaging/latest/reference/notifier.html>`_) that
|
|
indicate various events which occur, such as when a node changes power states.
|
|
These can be consumed by an external service reading from the message bus. For
|
|
example, `Searchlight <https://wiki.openstack.org/wiki/Searchlight>`_ is an
|
|
OpenStack service that uses notifications to index (and make searchable)
|
|
resources from the Bare Metal service.
|
|
|
|
Notifications are disabled by default. For a complete list of available
|
|
notifications and instructions for how to enable them, see the
|
|
:doc:`/admin/notifications`.
