I came across the MBean > Hadoop:service=HBase,sub=Memory,name=RegionServer It looks promising with > metrics on blocked flush time, etc. See below. All metrics are zero. I tried > to get it going. It is connected to the heap tuner facitlity that we might > want to turn on. I managed to get the latter going w/ below configs....
