Fixed In Version:	openstack-cinder-2014.1-3.1.el7ost	Doc Type:	Enhancement
Doc Text:	The Block Storage service now sends notifications for attach and detach events, allowing other OpenStack services (e.g. Telemetry) to listen for and display the results to the user. With these notifications, a volume's status can now be updated automatically in the Telemetry service. This, in turn, allows an administrator to search samples for volume status history.

Description RHOS Integration 2013-12-12 16:36:02 UTC

Cloned from launchpad blueprint https://blueprints.launchpad.net/cinder/+spec/attachment-notifications.

Description:

Send a notification when attaching and detaching volumes.

Those notifications would allow the volume status to be updated in Ceilometer
and add the ability for an admin to search samples for volume status history.

Without this notification, if volume_usage_audit_period configuration value for cinder-volume-usage-audit is configured to 'hour', a volume resource could still be considered "available" by Ceilometer although it has been attached 59 minutes and 59 seconds ago.

Moving to POST based on upstream status (Implemented).

Comment 3 Ayal Baron 2014-02-04 10:35:11 UTC

Eric, how can this be tested without Ceilometer?

Debug-level logs should show AMQP messages going out for these events.

Alternatively, any tool like qpid-printevents that can attach to the AMQP bus and print messages should show these if they are enabled in Cinder.
