I've created an HTTP-triggered Azure Function (V1) on Consumption Plan. When i watch the live metrics stream, the display constantly switches between "No servers online" and "3 servers online" in an interval of ~5 seconds. This happens under load and also when not a single request is hitting the function. I'm wondering if this is a display problem in application insights or if there is something wrong with my function app. Can anybody explain this behavior?

Funny, I experienced the same problem using a Azure Service Fabric solution so I suspect it has to do with the Application Insights Live Metrics Stream, not with the function app. – Peter Bons May 17 '18 at 10:26

Please share your app name with us privately along with a timeframe so we can investigate. Instructions [here](https://github.com/Azure/azure-functions-host/wiki/Sharing-Your-Function-App-name-privately). – mathewc May 17 '18 at 18:33

I just tried this on my own app, and I see my Live Stream flipping every few seconds between "No servers" and "1 servers online". So it does appear to be an AI Live Stream issue. The only thing I want to confirm is that after a while of no activity, your "3 servers online" should go to "No servers online" once the unused instances spin down. – mathewc May 17 '18 at 18:57

@mathewc that's correct. it looks like Azure Function autoscaling is behaving correctly but the livestream has got issues. – Markus S. May 21 '18 at 08:34
