By using gauges we're re-implementing stuff that coda hale does, namely
windowed stats. Just take a look at DRPCServer.java, like I mentioned.
You can use Meters or Histograms (I don't care). But they should both allow
you to delete a large amount of code. It should basically come down to 3-5
lines initializing the meters/histograms. Some of the current ones will be
combined, for instance `largestHeartbeatSize` and `averageHeartbeatSize` can be
combined into one Histogram automatically. Just set up a Histogram and mark it
with the heartbeat size whenever a heartbeat comes in.
Most of the work is just deleting code.
