As per agent logs, we receive error **System.PlatformNotSupportedException: Performance Counters are not supported on this platform**  
due to which System metrics won't be collected. Can Someone help me with this, we are using public API for manual instrumentation of our Application (windows service)

Hi,

the error is very clear: `PerformanceCounter` is only supported on Windows - I guess you are on Linux?

Best regards

@Wolfram_Haussig We have all windows servers on which applications are hosted. Not sure what are we missing here?
