monitoring manged thread cpu utilization

Neil Colvin

11/12/2002 3:37:00 PM

Is there a way to obtain the cpu utilization for a managed
thread? The ProcessThread class contains complete cpu
information, but the Thread class does not. Since there
seems to be no mapping from ProcessThread to Thread, there
is no obvious solution.

Hi Neil,

I've been researching this. Other than perfmon, I don't know of any way to
get that info through code. I'lll keep looking, but I have not found a way
to grab that info from the Thread class.

I have not found any way to use perfmon to get the info...it also monitor
ProcessThreads, not managed Threads.

This is a big development problem.. It is virtually impossible to do real
peformance tuning of managed threads without some way to do this!

Managed threads and OS threads map 1:1 in the current version of the CLR, so it should be easy to monitor them using perf counter
objects.

That is great...but how do I find the OS Thread (ProcessThread) which
corresponds to my ManagedThread so I can use the performance APIs to get
information about it (in C# code)?

I need to determine how much processor time a specific managed thread took
between two points in the code (and there are many mangaed threads running
sumtaneously in the application).
