cPanel logs most activity that happens on a server to log files so you can go back and review log entries for problems, instead of having to be on the server at the time of them happening.

This guide will cover the locations of the log files for things such as access logs, Apache web server logs, email logs, error logs, ftp logs, MySQL logs, and WHM logs.

If you'd like to have a poster of the 2013 cPanel logs location reference, you can request them from cPanel directly.

You can also view a digitial copy of this poster directly online at go.cPanel.net/logposter.
