I understood this part. I am facing a unique situation here. The alert based on the condition triggers fine . Now, after some time, the telemetry, based on which the alert was created, went missing. This does not happen often. At this point it should not resolve the alert.
Because if the alert has triggered at foo < 3, then it should resolve only when foo >= 4. Not at the time when the telemetry foo is completely missing. If this is an expected behavior, can you suggest how I can stop resolution of an alert when telemetry goes missing for an active alert?
