What exactly are you interested in monitoring? Different
tools have different uses. If your used to nagios and your
environment isn't that big perhaps you should take a peek
at groundworks -

I use a combination of nagios and cacti, nagios for event based
monitoring and cacti for performance monitoring/trending. My
cacti is *heavily* customized the result of hundreds of hours
of work and monitors roughly 11 million data points a day. Nagios
monitors about half a million.

But depending on what exactly your monitoring will depend on
what tool is best. e.g. how complex of monitors are you needing.
Do you just need PING and basic HTTP checks or are you looking
into more complex application level monitoring?
