linuxpol suggested looking into lsof. I looked into that and it doesn't seem to work for, e.g., mod_php. It might work for cgi, but I don't do cgi anymore so someone else (possibly you :-) will have to confirm that. Even if it works though, most scripts won't run for more than a few seconds, so you might not be able to use lsof for that. On my laptop, lsof for apache2 runs for long enough that I really doubt if it could find any script that didn't run for more than 10 seconds. Anyway, for mod_php, for instance, it seems that on apache2, the file is loaded, parsed, compiled into byte code and then closed. so lsof won't help there since that whole pre-processing bit generally will take fractions of a second. The default logging setup on my apache (yours too, probably) only logs apache requests when the request has ended. So you won't know that a script has run until it's finished running. If you want to know which scripts are running and what time they started running (e.g., if you want to figure out which scripts take a long time, maybe so long that the users cancel them), then you might look into mod_log_forensic. http://httpd.apache.org/docs/2.2/mod/mod_log_forensic.html that's not something you'll want to log all the time, probably. or if you do run it all the time, logrotate often. Note: I have not actually done any of the above. I was just curious about the question and looked around very quickly in the apache (2.2) documentation. So now I know something new too :-). tiger _________________________________________________ Philippine Linux Users' Group (PLUG) Mailing List [email protected] (#PLUG @ irc.free.net.ph) Read the Guidelines: http://linux.org.ph/lists Searchable Archives: http://archives.free.net.ph
