This shows how to use Munin on a CentOS 6 system.
First we need to install it:
yum install munin munin-node
After the installation of Munin we are going to set the most important parameters at /etc/munin/munin.conf :
dbdir /var/lib/munin htmldir /var/www/html/munin logdir /var/log/munin rundir /var/run/munin

htpasswd -c /etc/munin/munin-htpasswd Admin
And finally we fire it up:
Assuming that the web directory is already there just access it and get the graphs.
