[...]Thanks, this sounds interesting! Just to make sure I'm understood correctly: As we have to configure mod_wsgi and decide how many processes and threads we want to use some feedback from mod_wsgi would be great to tell us if our configuration setting for processes and threads makes sense. So I'm not asking for more statistics. :)

After playing around I came up with the following command to look into mod_wsgi:

top -H `ps -ef | egrep 'wsgi' | awk '{X=X" -p"$2}END{print X}'`

Although I can see the threads now the output is not that useful either. I think one is really interested in the time it takes until a request is picked by a free thread in mod_wsgi and processing starts? If it takes a long time until a request is picked it is an indication that all threads are busy and more threads could help? And this is something one can't measure from outside mod_wsgi of course.

Was this something you had in mind when you were trying to capture some statistics, Graham?
