HBase jmx stats

[Tim Sell]

I am collecting hbase stats from jmx.

Here's an example of the compaction stats from one of the region servers...

compactionQueueSize     0
compactionSizeAvgTime   19349729
compactionSizeMaxTime   566512933
compactionSizeMinTime   0
compactionSizeNumOps    8
compactionTimeAvgTime   83
compactionTimeMaxTime   1300
compactionTimeMinTime   0
compactionTimeNumOps    8

What does NumOps of compactionSize and compactionTime mean? is that
the total number of compactions ever?

Also, having a time suffix for compactionSize seems confusing. It
seems an artifact of this:

protected final PersistentMetricsTimeVaryingRate compactionTime =
    new PersistentMetricsTimeVaryingRate("compactionTime", registry);
protected final PersistentMetricsTimeVaryingRate compactionSize =
    new PersistentMetricsTimeVaryingRate("compactionSize", registry);
