You make a really good job with CSF, I really like this system.
Actually we use a lot ConfigServer Security & Firewall for have a look in log files like:
It's really nice to have fast access to log from WHM (whitout SSH) but one file is not here: MySQL log:/var/log/messages
/var/log/secure
/var/log/cron
..error_log
....
Are you able to add it in the next version ?/var/lib/mysql/$hostname.err
Best regards.
