[Xymon] creating custom graphs

I have a follow up question - I'm now able to get an rrd file generated on my xymon server - woot! But I don't have a graph to go along with it. I'm using data message type and this is what is in my rrd file - I'm under the impression that this should create a graph that shows up in my trends page, but no graph on trends page. The value that I'm sending is solcpu : 2 (percent cpu used). I'm guessing that is what is the the <last_ds> 2 </last_ds> field. Does anyone know what the other fields are?

I have some Solaris servers that I can't install the xymon binaries on so I'm going to try writing my own scripts to replicate the default xymon data. I successfully tested sending messages directly to port 1984 from my client to my xymon server, but I'm not clear on how data that is in graphs is sent/generated. For instance, if I wanted to generate a cpu graph, I can send the cpu values but I'm not sure what I would then need to do in order to generate the rrd graphs. Can anyone point me toward any documentation for this?

thanks, EJ
