domain user for a apache process

[oscar]

Hi Jason

Thanks, i know that The end web-user client has no correlation to any of the
user accounts on
your machine, but since the machines are only used for web hosting services,
it would be great if i had a structured method to know periodically wich
domains are the ones using lots of cpu, memory ...

i can control the bandwitch for every domain so this information gives me a
nice idea about it, however, there are sporadic times when a user is
overloading the apache web server with a cgi and it's hard to find with user
is responsible for the overload.
I had to temporarily shutdown some domains that they were almost crashing
the whole server and i was not able to just find wich domain was hosting the
script responsible for the situation.

how do you find the domain wich overloads the server with one script ( php,
perl ...) ???
i think apache logs and php logs are not enought to catch the user quickly
in an emergency.

I run mod_php with apache and works just fine, there are not problems, but
as i said, there are sporadic situations where i'd like to find a faster
solution to resolve and emergency

thanks
