Topic: Monitor Apache used threads

[zantoro]

Hello,
I have an apache running on WAMP.
From the http://httpd.apache.org/docs/2.0/mod/mpm_common.html#threadlimit page I understand that apache assigns a thread to every single user that connects to the website.
At the same time I know that based on the keepalive tag parameters a thread may stay busy a little longer.
Now my question: I would like to know if there is a way, using WMI or anything else to find out how many threads are idle (available) and ready to handle a connection and how many are busy doing something else.

Any help or hint would be appreciated.

P.S.: I tried querying WMI class W32_threads for the ThreadState and ThreadWaitReason but the ThreadState is the same for all of them (which doesn't help me to distinguish between the used thread and the idle ones).

Thanks,
Roberto.

With WMI, I cannot answer.

When you have ThreadsPerChild 250

In server-status you get e.g.:

4 requests currently being processed, 246 idle workers

I use that info in the Busyworkers Graph at www.land10.nl/apachestatus/

Hello,
thanks for your answer. this tool could be the solution to my problem but as far as I can see in the busyworkers.html I can only see the busy workers not the available ones.
How do you obtain the stat you just showed me:
"4 requests currently being processed, 246 idle workers"

Thanks again,
Roberto
