I think you should be able to put the graph definition into server/etc/hobbitgraph.cfg with a suitable name, then put that name into both the "TEST2RRD" & "GRAPHS" environment variables in server/etc/hobbitserver.cfg. Then send a suitable status message to xymon and the graph shows up.

I've just tried this on my laptop: mash two existing graph definitions together (cpu freq and battery capacity) into one called "batfreq". Add "batfreq" to "TEST2RRD" & "GRAPHS". Send test message:

 server/bin/bb localhost "status lorien.batfreq green `date`"

A short time later a new column shows up called batfreq. Clicking through thre green dot shows a single graph containing both battery capacity and 2 cpu frequency lines (dual-core cpu).

In your case, I think you might be able to get the combined graph to show up for each server by sending multiple status messages:

 server/bin/bb localhost "status server1.xxx green `date`"
 server/bin/bb localhost "status server2.xxx green `date`"
 etc...

all from one script. Or just define a new server name in bb-hosts and send one message. Either way, you'll probably want to have a regular status message going to Xymon so that the new column doesn't go purple.

I created a small script that scrapes info from several hosts/rrd's (connections to a particular IIS site) and puts it in a combined graph (see attached sample). I'm curious if it's possible to somehow create a "virtual host" in hobbit and use the hobbitgraph.cgi functions to create the graphs so I can also have the zoom & history functions.

This is the script that created the attached graph:

#!/bin/bash
