---------------------------------
Summary: Time based metrics will be reset after any get request
Key: HBASE-27316
URL: https://issues.apache.org/jira/browse/HBASE-27316
Project: HBase
Issue Type: Bug
Components: metrics
Affects Versions: 2.4.13
Reporter: Yunbo Fan
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.
