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 ?
