Oh, I see.  Obviously the counter values are totally different than 
would be appropriate for shoving into the *Spare hash entries.

I haven't looked at the rrd code in quite a while.  But, as I recall it 
was not very generalized and may be difficult to just "clone" for other 
purposes.  Creating usercode to log to a CSV should be pretty trivial; 
it's doing the graphing support from RRD to expose them to mh's web 
pages that is likely a lot more effort.  I would be tempted to consider 
just logging the data via DBI to a mysql DB and then massaging it from 
there; but, that's obviously a very different direction.  Unfortunately, 
I don't have any easy pointers to suggest.
