Invocation Statistics of EJB

ywtsang Jun 8, 2007 5:54 AM

From the web-console, I can see the Invocation Statistics of each EJB (session, entity, whatever). The statistics show the mix time/max time/total time/avg time/number of invocation of each method inside the EJB.

At that page, it links to the corresponding jmx-console page of that MBean of the EJB.

I think the web-console also use JMX to retrieve the invocation statistics of each EJB, but I hardly find how to achieve that by myself. As I want to get the invocation statistics of the EJB for the monitoring usage by other software like Hyperic HQ, I would like to ask how to get the invocation statistics through JMX? (what method to call? etc).

The best place to look for sample code is at the source code for twiddle, which is the command-line equivalent of jmx-console. The source can be found in the JBossAS source at console/src/main/org/jboss/console/twiddle[/command]. Look especially at the execute() methos in the *Command classes.

For a quick start, and example JMX code can be found at http://wiki.jboss.org/wiki/Wiki.jsp?page=HowDoIGetRemoteAccessToMyMBean

And the JMX docs are at http://java.sun.com/j2se/1.5.0/docs/guide/jmx/
