When I run
ps aux I get the following process table http://pastebin.com/NJsASBek that shows how much memory is being used by each one of the subprocess. We can see apache proceess are shown like this:
www-data 26487 0.0 0.9 245476 14920 ? Sl 17:32 0:00 /usr/sbin/apache2 -k start
Where 2687 is the PID but I have no idea if that belongs to either foo1.domain.com or to foo2.domain.com or to fooX.domain.com etc...
How can I know which is the site (for example the ServerName) of those PID showing?
This is how my apache sites are defined http://pastebin.com/mcew79sH of course I am willing to edit my apache sites if needed.
