Apache process at 100% - How to troubleshoot ?

[Superkikim]

Hi,

I have some Apache processes that use all my four cores at 100%. This is most probably a PHP script issue.

How can I troubleshoot that ? Is there anyway to dig an apache process to know what is running behind it ? what script, for what domain ?

Did you tried to analyse apache logs at least? Is there anything suspicious?

apachetop can hel as well.
