Doc Type: Enhancement
Doc Text:
To improve performance, if Event and Monitor tasks stop for any reason, they are restarted automatically. If the automatic restart fails, an alert is triggered. Furthermore, if multiple instances of the Event and Monitor tasks are running, they now stop automatically and only one instance of each task runs.

Description Ashish Humbe 2019-03-29 13:53:54 UTC 
Description of problem:
[RFE] If Listen On Candlepin Event and Monitor Event Queue tasks stops for any reason then it should be started automatically and alert should be triggered it these tasks fail to start.

These 2 tasks are important for the satellite to function properly, so satellite should monitor the state of these tasks and try to start them. 

Version-Release number of selected component (if applicable):
Satellite 6.x


Actual results:
Currently, the Listen On Candlepin Event and Monitor Event Queue tasks either stops working silently or multiple instances of these tasks are running which creates a problem and users do not get any alert of it. 

Expected results:
If any of these tasks stop for any reason or multiple instances of these tasks are running then those should be cleaned automatically and only one instance should be running.

Hello Ashish. How can I make one of these tasks to stop? Asking because I have no idea how to test potential fix. Also by saying 6.x is it safe to assume 6.4.2 is affected?
Comment 3 Ashish Humbe 2019-04-29 10:34:52 UTC 
Hi Jan,

Sorry for the delay, 

There is no easy way to find out why these tasks stopped working but for testing/QE purpose may be we can update the state of the task to Stopped using foreman-rake command or some other similar ways. 

Yes, for now we can set 6.4.2 version but it impacts all the satellite versions.  

Thanks,

Moving this bug to POST for triage into Satellite 6 since the upstream issue https://projects.theforeman.org/issues/27674 has been resolved.
