It would be super nice to have RPC query call logging per region server. Sometimes we have 'hot' regions getting hit by users, and this drives the CPU on a particular RS server up, except we have no idea what table it might be. I could rig the tcpdump on port 60020, and log things with AWK, but that would be super hacky. An insight what traffic drives the cpu will allow us (or anyone else) model the tables to user patterns accordingly.
