Munin is network monitoring tool for servers. It uses RRDTool, an open source used to generate graphics and logging server activities.
I am installing and configuring munin on centos 5 x86_64 using yum.
1)First of all, we need to add a RPMforge repository.
rpm -Uhv http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS//rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm
2)Installing yum
yum -y install munin
3)chaning the ownership of munin web docroot to munin, as by default it goes to root.
chown -R munin:munin /var/www/munin/
