PerformanceCounter specifications ?

• CostanzaFV

  Well, yes (mostly) and no (a bit). Yes because those pages indeed gather the various performance counters in a readable fashion. No, because this documentation is nothing more than the concatenation of the intregated help associated to the Performance Monitor app in WinXP. It would have been interesting to have a more structured and detailed documentation. In my view, those pages do not meet the usual .Net documentation quality (which quite quite high).

  Hi,

  
  
  

  BUG: NextValue method of .NET PerformanceCounter object returns zero

  SYMPTOMS The NextValue method of the .NET PerformanceCounter object may return zero (0) for the following LogicalDisk or PhysicalDisk performance counters:

  ?	% Disk Time
  ?	% Disk Read Time
  ?	% Disk Write Time
  ?	% Idle Time
  ?	Avg. Disk Queue Length
  ?	Avg. Disk Read Queue Length
  ?	Avg. Disk Write Queue Length

  
  Is there any way I can find the disk utilization (i.e 100 - % Idle Time) through the performance counters available in .NET or by any means through .NET framework. I will be thankfull if you can help me with this bug of .Net Performance counters.

  I am also wondering why the .Net specific performance counters (all the ".NET CLR foo" counters) cannot be accessed in a more object-oriented fashion (like enumerations or constants provided within .Net).

  Did these URLs answer your question   If not, could you please provide some more clarification

  Actually I am refering to the OS independant performance counters which include the .Net performance counters, and the basic hardware (memory, processor, disk).

  Here's a place that describes the Windows counters:
  http://msdn.microsoft.com/library/default.asp url=/library/en-us/counter/counters1_lkxw.asp frame=true
  
  And here's something similar for the Framework:
  http://msdn.microsoft.com/library/default.asp url=/library/en-us/cpgenref/html/gngrfPerformanceCounters.asp frame=true
  
  To find these I searched on msdn.microsoft.com for a specific counter plus "performance counter".  For example: ".net clr memory performance counter" found me the Framework page.

  Are you referring to OS counters or application counters   Information on OS counters should be somewhere in the windows documentation, and information on application counters should be available in the documentation for that application, I am unaware of a spec where they are described together.
