I think I've seen this before - it's probably because of an issue with the performance counters on the microsoft side. It looks like the following has resolved it for others:
At cmd run:
unlodctr .NetFramework and press Enter
cd to Microsoft.NET directory (C:\WINDOWS\microsoft.net\Framework\v4.0.30319)
After, restarted service to collect memory data.
The fix was derived from this article: https://support.microsoft.com/en-us/kb/922775
This could also be a permissions issue where the userID running the app pool does not have permissions to access perfmon stats. The username running the app pool has to have priviledges to the perfmon statistics and that user has to be a member of the Performance Monitored Users group.
and how can I check if the user running the application pools has permissions to access perfmon stats? My customer says the user is member of Performance Monitored Users group:
but I don't see any data in Generation 0, Generation 1, Generation 2 and Large Object Heap for the monitored processes (for example for GotMaster-SECTOR):
Are you able to see data for the counters in perfmon on the server i.e charting these counters in perfmon? If you are unable to see the data there you definitely will not be able to have them show up in Dynatrace. Open perfmon on the server and verify you are seeing data for these counters on the server.
Any news if/how you got it working?
I got the same problem. The user is in both gorups but I get no data and the permission denied error. I checked with perfmon and the data is all there.
