Hi Xin, The usual approach is employing the monitoring solutions common to server operations. Hadoop and HBase export JMX metrics as well as Ganglia contexts. Both can be used to graph the performance of either system. That also includes the JVM and its heap usage etc.
See this page for details: http://hadoop.apache.org/hbase/docs/r0.20.2/metrics.html <http://hadoop.apache.org/hbase/docs/r0.20.2/metrics.html>Lars 2009/12/14 Xin Jing <[email protected]> > > Hi all, > > I am a newbie in HBase usage.
