SLES 11.1 x64

Attempting to monitor this OS with Nagios. I am running Novell OES 11 on top of it as well. I'd like to monitor the eDirectory services in particular. However, i'm having quite a bit of difficulty getting everything up and running. I'm a noob to Nagios so if someone could recommend a step by step install of NRPE or at least how to get it working I would appreciate it!

I've tried to install nagios and it's plugins from YAST but i don't know where to go from there.

Thank you for any assistance you can provide!
