I'm using Azure Function App, in Application Insight-performance, I'm able to see the CPU usage of each instance but not memory or IO rate...
What could be the reason? Thank you!
I tried to reproduce the issue by watching the metrics, logs of the Azure Function App (Python Stack) as it is showing most of the metrics like Server Requests, Response, Success and Failure logs except the Memory working set and few.
But as per this MSFT documentation I came to know that
Memory data isn't a metric currently available through Azure Monitor. However, if you want to optimize the memory usage of your app, can use the performance counter data collected by Application Insights. This metric isn't currently supported for Premium and Dedicated (App Service) plans running on Linux.
Refer Azure Monitor Performance counter metrics to learn more Information.
