I have made some headway on this - what I was looking for was a simple set
of HTML comment tags <!-- Comment -->

So now I have my data embedded in the message thus:

It doesn't show up on the web page, and I can happily parse it with my
custom rrd handler script (I really must get to grips with moving it to
C...).

But now I'm having trouble with the hobbitgraph.cfg entry.  What I want is
a series of stacked graphs, one for each rrd file, showing used space over
total space.  But I can't figure out how to specify multiple sources with
FNPATTERN, but ask rrdgraph to create a unique graph per file rather than
trying to combine them like disk etc.

I can't see any useful switches in the rrdgraph man page.  Can anyone help
with this?

TIA,
Andy.
