I know cloudkick is doing something like this, and we're developing our own in-house method, but it would be nice for there to be a generically-available package that would do this. Lately I've been wishing that someone would take graphite (written in python) and put the frontend on top of cassandra instead of their proprietary whisper databases. The counter support in 0.8 should help with keeping the rollups up-to-date.
