Hi, I am new with Hbase and try to extract HBase metrics by JMX, so I
noticed that "NumOps" metrics reset periodically, but How I see in code
(RegionServerMetrics.java class) they shouldn't.
That what I've got on my mashine:
21:11 (my local time)
compactRegionNumOps java.lang.Integer = 0
regionServerReportNumOps java.lang.Integer = 0
abortNumOps java.lang.Integer = 0
balanceSwitchNumOps java.lang.Integer = 0
*compactionSizeNumOps java.lang.Integer = 3
flushTimeNumOps java.lang.Integer = 4*
fsReadLatencyNumOps java.lang.Integer = 20
atomicIncrementTimeNumOps java.lang.Integer = 0
fsSyncLatencyNumOps java.lang.Integer = 65
fsWriteLatencyNumOps java.lang.Integer = 54
*compactionTimeNumOps java.lang.Integer = 3
flushSizeNumOps java.lang.Integer = 4*
21:27 (my local time)
compactRegionNumOps java.lang.Integer = 0
regionServerReportNumOps java.lang.Integer = 0
abortNumOps java.lang.Integer = 0
balanceSwitchNumOps java.lang.Integer = 0
*compactionSizeNumOps java.lang.Integer = 1
flushTimeNumOps java.lang.Integer = 2*
fsReadLatencyNumOps java.lang.Integer = 739
atomicIncrementTimeNumOps java.lang.Integer = 0
fsSyncLatencyNumOps java.lang.Integer = 51
fsWriteLatencyNumOps java.lang.Integer = 781
*compactionTimeNumOps java.lang.Integer = 1
flushSizeNumOps java.lang.Integer = 2*
My Q is: should compactionTimeNumOps, flushSizeNumOps and so one reset
state or they should save their state?
With best regards, Vladimir Tretyakov, Sematext
