hbase metrics contains different types:RegionServerMetrics and RegionServerDynamicMetrics. And there are more metrics emitted from RegionServerDynamicMetrics, especially in case that there are more regions in RS. RegionServerMetrics and RSDM share one metrics context, which makes the control become difficult.
In our production, we add a metrics filter in MetricsContext, which can be configured as to our needs, which will reduce the amount of metrics, and take a good effect. 2013/9/24 Otis Gospodnetic <[email protected]> > Me, too! > > Otis > -- > HBase Performance Monitoring -- http://sematext.com/spm > > > > On Mon, Sep 23, 2013 at 7:10 AM, Arati Patro <[email protected]> > wrote: > > Hi All, > > > > > > I have the same query.
