Invocation counters stuck at zero despite Azure Function running fine

Question

Hello

An Azure Function (in C#) I manage has been running multiple times per hour for a few months already.

This is confirmed by the fact that it performs the task it's intended to do and by the following graph, that is shown in the "Overview" blade of the Function App:

Surprisingly, when I open the "Monitor" menu of this function, the "Invocations" tab remain with the "Success" and "Errors" counter at 0. I remember seeing meaningful values on this tab in the past, but now it's gone.

What could explain this strange behavior? How to get this counters back to normal? Thanks for your help

Hi @Bruno Heridet - Since all monitoring for Azure Functions is done with Application Insights by default, could you confirm if your Application Insights config is intact and that you're capturing logs there?
