Thread-topic: alarm transition events are missing in kafka queue - mysql alarm state is updated properly

Hi Roland,
This is Yuan Pen from Deutsche Telekom. I am sending this email to the monasca community asking for help on monasca threshold engine. We have found that when sometime alarm state transitions happened, the threshold engine updated mysql alarm state properly, but failed to put  state transition events  in kafka queue (alarm-state-transitions).  Does this ring a bell to anyone in the community? If this is a real problem, is there anything we can do to make sure the event in transition queue and state in mysql is synched? Any comments or help are greatly appreciated.
Best Regard,

Yuan Pen
