alert when a metric sample is no longer sent (missing data)
Please support the ability to configure an alert rule to trigger then the associated metric data is no longer sent (missing data)., so that we can detect issues with the application that result in lack of data. The alert shall auto-resolve when data next arrives (and if the threshold criteria is satisfied).
we have not closed on a plan at this time. As a workaround however, please note the update here: https://visualstudio.uservoice.com/forums/357324-application-insights/suggestions/14428134-add-alerts-based-on-results-of-analytics-queries. With the support for metrics derived from analytics queries, you can track an aggregate of the data received, and set a different number when there are no results. Let us know if that works for you.

Can't find this in my search so I'll post this and see if I get any feedback.
I'm creating some alerts in Azure related to a specific request per server. My goal is to trigger an alert when the count for a 10 minute window is equal to zero. I did some testing after setting up the query and alert but didn't get it to fire. I traced it back to the COUNT being non-existent since there was no data to count.
Looking for a way to monitor this type of scenario where it would trigger the alert if there are no requests over a certain time period.

That definitely makes sense for my usage too. Such alerts may helps us to be proactive.
Up up !
