  • Hi,


    I have the same 'issue', as far as I understand this is just the alerting being a bit trigger happy.

    The logical situation should be:
    1. Does not exist -> This triggered the monitoring system to: restart

    2. Exists -> This triggered the monitoring system to: alert

    3. Execution failed -> This triggered the monitoring system to: alert

    4. Execution succeeded -> This triggered the monitoring system to: alert


    The expected situation is service running and being responsive. If that's not the case even for a second (e.g. after restart), the monitoring has a bit of a meltdown.
