Zaqar Configuration

Vitrage can be configured to notify raised or cleared alarms to Zaqar (the OpenStack Messaging service)

Enable Zaqar Notifier

To enable Zaqar notifier, add zaqar to the list of notifiers and add the zaqar queue in /etc/vitrage/vitrage.conf file:

[DEFAULT]
notifiers = zaqar

[zaqar]
queue = <zaqar queue name to post the message>
