Hi Justin,
Thanks for the quick response! At least I'm getting something, although not the desired result. Now the GUI gives these response:
Check ROOT Disk Free Space OK 10-14-2008 10:35:50 0d 0h 4m 30s 1/5 NRPE v2.10
Check Remote Mail Queue OK 10-14-2008 10:38:27 0d 0h 6m 53s 1/5 NRPE v2.10
Check Remote Number of Users OK 10-14-2008 10:39:22 0d 0h 5m 58s 1/5 NRPE v2.10
Check Running Processes OK 10-14-2008 10:35:16 0d 0h 5m 4s 1/5 NRPE v2.10
Check Swap Space OK 10-14-2008 10:37:22 0d 0h 2m 58s 1/5 NRPE v2.10
Check USR Disk Free Space OK 10-14-2008 10:36:48 0d 0h 3m 32s 1/5 NRPE v2.10
Check VAR Disk Free Space OK 10-14-2008 10:37:45 0d 0h 2m 35s 1/5 NRPE v2.10
So how do I get the data I'm looking for, instead of "NRPE v2.10"?

Grant, try to setup the check so it's not sending any args from nagios
or looking for any ARGS on the remote host, just so you can troubleshoot
it. ie.
on nagios server:
$USER1$/check_nrpe -H $HOSTADDRESS$ -c check_disk
Once you get a working response, you can start adding in a few ARGS.
Good luck.

So I made a sym link between the two directories so that nagios can find it. The check_nrpe was also owned by root, so I changed it to be owned by nagios.
