Frequently Asked Questions
I don't need notifications on the message bus. How do I disable them?
Notification messages can be disabled using the noop
notify driver. Set notification_driver = noop in your
configuration file.
Why does the notification publisher create queues, too? Shouldn't the subscriber do that?
The notification messages are meant to be used for integration with
external services, including services that are not part of OpenStack. To
ensure that the subscriber does not miss any messages if it starts after
the publisher, oslo.messaging ensures that subscriber
queues exist when notifications are sent.
How do I change the queue names where notifications are published?
Notifications are published to the configured exchange using a topic
built from a base value specified in the configuration file and the
notification "level". The default topic is notifications,
so an info-level notification is published to the topic
notifications.info. A subscriber queue of the same name is
created automatically for each of these topics. To change the queue
names, change the notification topic using the
notification_topics configuration option. The option
accepts a list of values, so it is possible to publish to multiple
topics.
