Well yes that would seem to work.  But it just seems redundant to have
to list "fans" in multigraphs and then also enable it with
"TABLE:rrd()" where I want it.  Why couldn't multigraphs just be the
default for everything?  Perhaps its a performance thing?  Perhaps I'm
missing something.  I guess I'm still a bit confused by it all.  I'm
not proposing a change to the way Xymon/Devmon work, just trying to
understand how they work.

By specifying "linecount" in the template.  If it's <= 0 it shows as a
multi-graph.  If it's >0, it shows several single-graphs.  If by
"graph definitions" you mean the contents of graphs.cfg, then I that's
not what I'm referring to.

Well, my new "fans" template that I'm developing has graphs because it
shows fan speed, but all of the standard package of templates have no
graphs for fans because most fan OIDs don't show fan speed.

Already mentioned on the devmon-devel list.  I will submit a patch soon.
