Description Jason E. Rist 2018-04-19 15:12:15 UTC 
Cloned from launchpad blueprint https://blueprints.launchpad.net/mistral/+spec/mistral-zaqar-publisher.

Description:

OpenStack users would benefit from receiving Mistral events. Mistral is capable of sending these but doesn't have a way to send events over Zaqar. These events would include information about when workflows start, stop, fail etc. and would allow the different clients to earlier detect changes and failures in Mistral.

If a workflow fails with an unhandled error, the clients may never receive notification of this. Currently they would need to poll mistral. However, with these notifications they would be sent by Mistral regardless of the workflow errors.

Mistral recently gained a notifier for sending event notifications. However, it doesn't currently support Zaqar. This support should be added. A rough patch which dosn't work, but is a start can be found here:

Comment 1 Jason E. Rist 2018-04-26 15:05:05 UTC 
This could be very useful for the UI, especially given other RFEs/bugs like this:

Comment 2 Jason E. Rist 2019-04-18 18:42:08 UTC 
This was originally intended to help the TripleO-UI. It will not be making it in as the product faces deprecation soon. Closing as WONTFIX.
