Lars Hofhansl commented on HBASE-11702:
---------------------------------------
bq. Not worth the effort of making RS-wide metrics out of that.
Seems like a very useful metric to me. If we had total bytes/KVs flushed, total
bytes/KVs minor, and total bytes/KVs major compacted per region server that
seem to be very useful metrics.
Would only need to collect the metric locally per flush/compaction and then
update the RS metric with the total for the flush/compaction.
