I've never done Nagios - I don't want to think about anything that needs
per-host configuration and I want to get router/switch/link details in
the same tool. 'Getting it running' should be a yum install these
days plus configuring a discovery range which you can now do through the
web interface. If you have a server for a test install and the same
snmp community string everywhere it should be painless to test.
The one thing I find a bit cumbersome is building pages with the graph
groupings that I want to see together. It's not a difficult process,
just several steps to pick and position each one on a page. But that's
just for convenience - you can go to the node page and pick graphs
individually without this.

I tried WMI on opennms a while back and couldn't make it work, but I'm
sure it is much better now. As for documentation in general, you
shouldn't need much to get started and the mail list is pretty good if
you have specific questions. In fact I usually look at mail list
archives before making choices like this. If people are asking about
problems with the basic application functionality I'm less likely to try
it than if the discussions are about adding new stuff or extensions.
