I am experiencing a strange issue with the performance monitor in Windows 2008 R2 (that has been updated with the latest patch. Specifically I am attempting to save the Total Method Requests Per Second. I am saving the counter out as a .csv file (though I have tried saving it out as a bin file) and the counter simply isn't showing up - most of the time. I am running the counter in conjunction with Stocktrader (the .net 4 version). Has anyone else experienced this issue? It seems that this is a bug in the performance counter as the issue seems sporadic. Any help would be greatly appreciated. -B

Have you checked event viewer for any "perfmon" related errors? If so, what do you get? Also, have you tried manually rebuilding the the perfomance counters associated with .NET? The shortcut method is to run a cmd prompt using an account with local admin priviledges and type lodctr /R Notice the 'R' is capitalized. Then hit enter. That does not always get the job done for custom .NET apps unfortunately. To rebuild the counters manually check out http://support.microsoft.com/kb/300956 Pay special attention to the "Rebuild any custom .NET Framework assembly performance counters" section. -DP
