DEVMON, xymon, and TABLE

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.

 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.

Thanks!

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

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

I doubt it is the actual RRD collection that is the problem, otherwise you 
probably wouldn't see a link to a graph ... however you should show the output 
of something like:

rrdtool info $BBRRD/hostname/power.rrd

According to your rrd option to the table statement in your message file, the 
DS name in the hobbitgraph definition should be ds0 or ds1, not "lambda".

Will we see the devmon template?

That's a good point Buchan.    I'll have to test it on something else.

I found the nonhtml option and converted this into an NCV graph which is
working perfectly now.

Once I get the template squared away, I'll submit to the project.   I
imagine it'd be a good template for other networked PDUs.

So changing "lambda" to "ds0" was not sufficient?
