Web App Service - PerformanceCollectorModule, added counters not displaying

[williamjv9]

I’m unable to get “Add PerformanceCounter” to work for our deployed Web App Services.

1. I’ve added the SDK to my .Net (4.6.1) project via VS2017
2. Installed https://www.nuget.org/packages/Microsoft.ApplicationInsights.PerfCounterCollector/
3. Added a list of counters in ApplicationInsights.config
   Example list:
   Add PerformanceCounter="\Process(??APP_WIN32_PROC??)\Handle Count" ReportAs="Process handle count"
   Add PerformanceCounter="\Process(??APP_WIN32_PROC??)% Processor Time" ReportAs="Processor Time"
   Add PerformanceCounter="\Process(??APP_WIN32_PROC??)% Process CPU" ReportAs="Process CPU"
   Add PerformanceCounter=".NET CLR Exceptions(??APP_CLR_PROC??)# of Exceps Thrown / sec" ReportAs="CLR Exceps per sec"
   Add PerformanceCounter="\Process(??APP_WIN32_PROC??)\Private Bytes" ReportAs="Private Bytes"
   Add PerformanceCounter="\Process(??APP_WIN32_PROC??)\IO Data Bytes/sec" ReportAs="IO Data Bytes"

4. Deployed the service.
   

After following the above steps, the added counters don’t appear on the Metrics Explorer blade.

I do see some of the default counters populating; Server Requests, Server Response Time, Failed Requests, etc…

Server counters "\Processor(_Total)% Processor Time " and "\Memory\Available Bytes" don't populate and remain gray with ---

Any thoughts as to why I can’t get system level and custom counters to load?
