I'm reading this article about
Apache mpm configuration tuning. And the author shows how to get the amount of Virtual Memory apache is using like this:
ps -A | grep apache
But this command shows me multiple apache processes:
11188 ? 00:01:36 apache2 17821 ? 00:00:02 apache2 23682 ? 00:00:00 apache2 23720 ? 00:00:00 apache2 23790 ? 00:00:01 apache2 23800 ? 00:00:00 apache2 23803 ? 00:00:00 apache2 23805 ? 00:00:01 apache2 23881 ? 00:00:00 apache2 23884 ? 00:00:00 apache2 23900 ? 00:00:00 apache2
Do I need to know how much memory single process uses or all of them to put in this formula:
Generally number of MaxClients=(Total RAM memory – RAM memory used for other process except Apache process) / (Memory used by Single Apache process)
It looks like I need to know the memory usage for a single process, but for which one out of the list?
