[xymon] DEVMON, xymon, and TABLE

Patrick,

Hey all, Just want a sanity check here to make sure I'm not losing my marbles.

Does the TABLE option inside devmon's message syntax only produce graphs for certain tests?

I'm trying to use it to map the power usage for my PDUs, I have the data being collected (mostly) properly and stored in the rrd files.

However, when I look at the status column, I'm just getting the link to the file and not the actual graph.

Do you mean that the graph image is broken, or is it completely missing? If it's broken there could be a problem with an RRD file - easy enough to create some extras if you've been tweaking a devmon template. Check the RRD directory and see if there are any extras that match the FNPATTERN. The other gotcha, now I think of it is that the FNPATTERN is a regexp, and note that it doesn't start with ^power - so if you have ANY RRD filenames containing the substring power they will match. Try changing the FNPATTERN line to:

--hobbitgraphs entry -- [power] FNPATTERN ^power\.(.+)\.rrd

I've reviewed Vernon's graph troubleshooting guide and everything is good.

I guess if this doesn't work, I'll have to figure out how to write out the individual branch elements in devmon.

Have you added 'power' into GRAPHS= line in /etc/hobbit/hobbitserver.cfg ?

David.

Thanks! --patrick
