My name is Vijesh and from india..
I need Ur help in Configuring Nagios on RHEL 6, please provide me with steps to configure it..
Waiting for ur reply :-)
That's really old :S
IIRC there's a spec file in the nagios sources. Use that to create an rpm and install nagios in your system.
Nagios might seems overwhelming at the beggining but in the end is pretty straightforward :)
