I'm running a Linux2 webserver on Amazon EC2 which is hosting a number of (mainly wordpress) websites.
Every day at about the same time the server CPU jumps to run at 100% CPU for about an hour.
Using the Top command i see that an instance of httpd is running at 90%+ CPU.
How can i determine which specific site is causing this?
Is it possible to equate the PID to a website?
any other ideas how i can isolate the cause?
