How I used to evaluate the performance of load balancing for my cluster is to observe the CPU usage on every node. Today I found that the JMX MBean jboss.management.local could also show some information about load balancing. For example, I have a SLSB in my application called ClinetUtility Then the statistic information about the usage of this session bean can be found under jboss.management.local:EJBModule=xx.ear,......,j2eeType=SLSB,name=ClientUtility e.g getArrayFromDB=[Count: 14606, min time:0, Max Time:1437 Total time:7623773, Request Rate:52.0(Description:.......) ] Then I can compare this statistic info on different node and see the difference to evaluate the load balance. Do you also think this is a good way to do so? Does somebody know the meaning of Request Rate? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4235634#...
