How to find out which file is loading the processor?

Question

PHP

Hello.
Several processes load a lot of the processor. How to find out which file is running?
I see only the process (there are about 20 of them, 2 of them load percent under 40%)
/usr/sbin/apache2 -k start

Answer 1

It does not necessarily load the processor file. It can be an infinite loop or a processor-intensive mathematical calculation. You can be tritely DoSit.
