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. diff --git a/doc/source/index.rst b/doc/source/index.rst index 6e4681d..8e71671 100644 --- a/doc/source/index.rst +++ b/doc/source/index.rst @@ -22,6 +22,7 @@ Contents opts conffixture AMQP1.0 + FAQ contributing Release Notes |
