I use Nagios at work on a CentOS install, the company I work for use SME (
God it's horrible ) but it's also based on CentOS so you can work your way
round it.

Feel free to fire questions at me, guys in #nagios on Freenode are very
helpful I've found as well.

Looked at OCS but not used it in anger yet I'm afraid.
