WHM / cPanel : Munin MySQL Graphs blank

Make sure that the password in /root/.my.cnf is valid, first.

In /etc/munin/plugin-conf.d , you will see a file called cpanel.conf . Modify it completely to look like so:


user root
group wheel

env.mysqladmin /usr/bin/mysqladmin

env.mysqlopts -u [MySQL_usr] -p[MySQL_usrpassword]

### [MySQL_usr] is a valid MySQL user and [MySQL_usrpassword] is it’s password
### you can use mysql root too.

group mail

group mail

user mailman

then restart munin

/etc/init.d/munin-node restart

This tells munin to pull the mysql environment from the file necessary
Of course , in this case you will need munin to run as ROOT. To do this:
su to your munin user

su munin

remove the munin crontab

crontab -e

remove the line, or just add an # to the beginning of it

then exit out of the shell, and add the SAME crontab (that was in the munin user) to root, adding –force-root to the end of the statement, so it’d be something like:

*/5 * * * * /usr/bin/munin-cron --force-root
