I made a quick PHP web-based tool to grab all the errors from cPanel's chkservd.log for a given date or date range. Aside from grep, less, and guessing with tail -n how many lines back last week or last month starts at there was no easy way to do this.
Since it's PHP there's open_basedir restrictions which may need to be considered, but the script can look for chkservd.log in /var/log, /tmp/, or ./
Almost all the info can be found here:
"Almost" meaning you'll have to get the script in some docroot you can access it by--it surely won't "install" itself.

codenode.com is not commercial; neither is FlexCP and their links.
