So go to  /usr/local/cpanel/3rdparty/share/munin/plugins/ and look for the file of the plugins you are looking for, if plugins are not there it might be in munin official site https://github.com/munin-monitoring/contrib/ OR  you can find more information on http://munin-monitoring.org/wiki/Documentation

Installing plugins that exist in CPanel

If you find your plugins at /usr/local/cpanel/3rdparty/share/munin/plugins you have to create symbolic link of that file to /etc/munin/plugins folder.

for example if the plugin file name is myplugin then:

ln-s /usr/local/cpanel/3rdparty/munin/plugins/apache/myplugin   /etc/munin/plugins/myplugin

once the symbolic link is created edit the config file cpanel.conf inside /etc/munin/plugin-conf.d

so :

Vi /etc/munin/plugin-conf.d/cpanel.conf

add new lines in the file as:

[myplugin]

user root
group wheel

#You can add your other user and group settings and also passed extra parameter.

Once its saved, restart the munin node by

service munin-node restart

it will take 10-20 min to graph to be appear on the WHM munin plugin.
