In HBase 0.92.x, you can view metrics in the HBase UI if you set + *.class in $HBASE_HOME/conf/hadoop-metrics.properties + to org.apache.hadoop.metrics.spi.NoEmitMetricsContext. For + example, to see hbase metrics, set hbase.class to + +hbase.class=org.apache.hadoop.metrics.spi.NullContextWithUpdateThread + +

+

After restarting HBase, browse to /metrics in the regionserver + or master UI to see a dump of the current metrics state. +
