I have an Application Insights availability rule set up to monitor a Health end point of my application. During scheduled down time the alert repeatedly activates and deactivates, even though no successful availability checks are logged. I would expect it to activate after the down time starts, and deactivate after it's done, but I get repeated activation / deactivation notifications.
I have my Alert set to fire "Whenever the average failed locations is greater than or equal to 2 count".
I look at my Availability Check in the Azure portal and there are no successful checks during this period.
I have a similarly configured Availability Check for another application that works as intended, with almost the exact same configuration, so I'm stumped as to why this one is producing false deactivations.
