You can also run an ext script on your xymon server, connect to the system via ssh as a particular user and have that user's shell be whatever command it is that you need to run to collect whatever data (or use the ssh "command" option for authorized_keys). The command's output comes in on STDIN and you can then process it  in the ext script.
