Hmm I did consider storing the stats in mnesia, but I really wanted the
graphing power of RRDtool.   Didn't really consider exposing stats  
via snmp
though. I have a, likely irrational, dislike of snmp due to various  
problems
in large polling implementations, which I would have to do to get the
data back into RRD somewhere.

With my current strategy, whenever the application code adds a new  
statistic it will
automatically be collected,  I suppose I could have a snmp approach walk
an entire leg of some tree on every poll, so that would do the same  
thing.

Thanks for the suggestion, it's worth some thought.
