How can I count the # of active PHP scripts?

[JonBlockBoston]

I'm trying to find out how many concurrent apache threads are executing a certain file. For example, if I had a file called "test.php", I would want to know how many apache server threads are currently running that file.

I looked at apache's mod_status with the "ExtendedStatus On" option, but I'm unable to get php files to be detected.

Any ideas?

I was going to suggest using a system call and a combination of ps and grep, but I'm not certain that you obtain quite what you're looking for. It's worth poking into though. If you can find a way to tell from a shell then you can automate it with PHP, most times.
