Have you ever had a situation where you find yourself debugging a dump from ASP.NET when suddenly you notice you forgot to get the Performance Monitor log?

 

If sometimes you face this situation, I have great news for you: this script shows you some of the main .NET Performance Monitor counters. It gets the information from the ASP.NET process or dump being debugged.

 

This is one of the coolest scripts I have!

 

Take a look at these screenshots:

 

 

 

 

 

  

 

Source code for GET_PERFMON.TXT:

$$

$$ =============================================================================

$$ Get Performance Monitor counters from mscorsvr.dll or mscorwks.dll.

$$

$$ Compatibility: Win32/Win64  (This is a new version from 01/30/09)

$$

$$ Usage: $$>< to run the program.

$$

$$ Requirements: Public symbols.
