we've got a cron which iterates each topic+partition and
writes an index of timestamps->byte offset, so it was
easy to hook from there into graphite. but graphite couldn't
do 2000+ derivative()s for a reasonable pageload time,
so we put the pre-calculated write rate into graphite.

what i'd very much like to have is per-topic read/write
stats by client ip.
