Installing Latest Nagios onto Ganglia GMETAD Machine

Ok, so once again I compiled my own RPMs from the latest tarball on the nagios website for the core, and plugin pieces. Needed gd-devel and libjpeg-devel as dependecies in order to create the RPMs, but that was pretty easy.

Installing Nagios was a slightly more challenging feat: had to install gd as a dependency, that was fine. But also needed "perl (Net::SNMP)" for Nagios to install properly from RPM.

First, I tried installing from CPAN, as my initial Perl instincts kicked in only to be met with total and utter failure.

At last, came across the correct yum package to install:

yum install perl-Net-SNMP -y

That fixed it all up for me. On to configuring it to work with Ganglia for email alerts!
