Description

When viewing http://<hostname>:8047/metrics#gauges
The gauges reset to near zero values and does not seem to update.
Tracing the server calls made, I see the following:

{version: "3.0.0", gauges: {G1-Old-Generation.count: {value: 0}, G1-Old-Generation.time: {value: 0},…},…}
counters :
  {drill.connections.rpc.control.encrypted: {count: 0},…}
gauges :
  {G1-Old-Generation.count: {value: 0}, G1-Old-Generation.time: {value: 0},…}
histograms :   {,…}
meters : {}
timers : {}
version : "3.0.0"

This looks incorrect and would explain why the metrics appear to be incomplete.
