Hi Sentil, From DotNetAgentGuide8.2.1.0.pdf, page 43:"the .NET CLR Memory performance counter category has performance counters such as # Bytes in all heaps, Gen 0 heap size, # GC handles, and % time in GC." In my system, I can see these metric under - see screenshot: .NET Process|appname|perfmon|.NET CLR Memory|w3wp.However, this metrics/counters are related to the CLR. As you know in a CLR several W3WP instances can exist. I believe, this values shown here are one instance related not overall to VM. I hope this helps, Regards,Sergio
