> Jmx metrics can be query by http request.
> But metrics will be reset after any get request.
> The root cause may be the implement of Histogram's method "snapshot"
> {code:java}
> @Override
> public Snapshot snapshot() {
> return histogram.snapshotAndReset();
> } {code}
> It will call snapshot and reset at the same time.
> I think it should not be reset cause we may need history metrics.
