Ever wonder where the MST looks to investigate events on your server when you submit a ticket? Knowing the locations of various log files for both cPanel and Plesk can be invaluable when trying to understand why, when or how an event occurred on your server.

Below are breakdowns of log file locations for both control panels. Be sure to check the handy (but large) graphic representations of cPanel/WHM log locations at the bottom of the page.
