If this hasn't gone anywhere and in the worst case this is what we did - you could have the nagios server (or whatever monitoring system) send email alerts to a mailbox on the xymon server, say the xymon user mailbox. You can then use procmail to pipe those emails to a script you write that parses and sends the message via the xymon client using a reformatted string. Some stuffing around but it can work well.
hope that helps, Phil

Subject: [Xymon] Xymon - Nagios interconnect
I am a happy user of Xymon -- thanks Henrik!
I have recently received a storage subsytem that includes a Nagios
monitoring system that will need to stay in place. Anybody have
suggestions/experience with gatewaying the Nagios alerts into xymon?
My hope is to somehow feed the Nagios alerts (and clears) into xymon so
xymon can tell me what I need to know.
