Finding specific function for high CPU in Azure Function App

I have an Azure Function App that contains a number of functions. I suspect one of these functions is consuming high CPU, is there a way to view the CPU usage based on the specific function?

    • Azure Portal – Function App Menu – Diagnostic Settings – Check the "Function Application Logs" and "All Metrics" and Send to the Log Analytics workspace (destination) that creates a diagnostic setting and save it.
      enter image description here

    In the Azure Portal – Function App – Diagnose and Solve Problems – Click on the "Availability and Performance" for CPU Analysis on Functions.

    • Make Sure you have enabled the App Insights resource associated with that function app is integrated.
    • In the "CPU Analysis", you can check the each instance CPU Usage and "CPU drill down" option is for App Level CPU Usage.

    Not Sure can we determine the CPU Usage per function because Scaling Controller control the scaling of instances due to/based on high CPU Utilization, I/O requests, High Utilization of Service Bus Queue, Storage Queues of Function App and only few information provided about CPU Usage in Function App by Microsoft.
