I've seen a few different channel feeds that maintain things like graphs
of where you're getting messages from, but beyond that I'm not aware of
anything like this.

This should be fairly easily fixable by accumulating them with your tool;
innd's architecture isn't particularly well-suited for doing the summary
itself (status.c does this to some degree, but it's a bit brute-force
about it and it still doesn't remember statistics across closes of
connections).

If I were you, I'd be inclined to use the existing log information as a
basis for generating these statistics.  I'd be interested to see what you
come up with if you end up with anything that seems to work; it sounds
like a useful idea.
