I've saved my performance counter settings to a .htm-file. When I reopen the performance counters by doubleclicking on the .htm file the Buffer cache hit ratio-counter always shows a zero-flatline. Other counters like avg. disk queue length do work.
It works correctly when I open the performance monitor itself and add the buffer cache hit ratio-counter.
Quite annoying...I got to select my perf counters each time again and again when I'm starting a new RDP session. Any clues on this issue?
Some system specifications:
* Windows Server 2008 R2 Enterprise SP1
* SQL Server 2008 (10.0.2766)
