RE: threads

Hi Steven,

I am looking to monitor similar thread counters for a web service and HTTP
application. For these I would like to know how many threads are being used
by each application and how many are still available.

This will allow me to see if any thread blocking is affecting performance
and if the thread pool needs to be increased.

Hello smarty,

As for the "web service" you mentioned, is it an ASP.NET web application or
webservice application or a native IIS web service?

For the two questions you mentioned, here are my understanding and
suggestion:

Q1. What is the difference between process:inetinfo:thread count and
process:w3wp:thread count?
==================================
Inetinfo.exe is the IIS service's main process, however, for ASP.NET
application, it is always hosted in another process. For IIS5, its
aspnet_wp.exe, for IIS6, it is w3wp.exe


Q2. Is this the right counter to measure threads in use?
===================================
Do you want to get the thread numbers available for processing the ASP.NET
requests or the total threads number in the ASP.NET's worker process?


for ASP.NET request processing, the runtime will always use pooled thread
from .NET CLR's managed thread pool( rather than normal thread) to process
client requests. the "process" counter's thread count is the total
operating thread number. Here is a very good article introducing ASP.NET
threading model:

#Microsoft ASP.NET Threading
http://support.microsoft.com/default.aspx?scid=/servicedesks/webcasts/en/tra
nscripts/wct060503.asp

Also, you can create a custom counter for pickup the ASP.NET managed thread
pool status:

Hope this helps.
