org.jboss.varia.counter
Class CounterInterceptor

java.lang.Object
  org.jboss.ejb.plugins.AbstractInterceptor
      org.jboss.varia.counter.CounterInterceptor

All Implemented Interfaces:: org.jboss.ejb.AllowedOperationsFlags, org.jboss.ejb.ContainerPlugin, org.jboss.ejb.Interceptor, org.jboss.system.Service

public class CounterInterceptor
extends org.jboss.ejb.plugins.AbstractInterceptor

Interceptor that uses the CounterService MBean to record the length of time spent in 'lower' interceptors (below it in the stack).

How to use:

First, the CounterService MBean must be installed in JBoss. See counter-service.xml for details/examples.

Next, you need to configure this interceptor into the interceptor stacks of any beans you wish to monitor. This can be done either globally for a container-config in standardjboss.xml, or on a per-bean basis in a jar's jboss.jcml. Just insert the following at the top of the <container-interceptors> section. If you're overriding this for a bean in jboss.xml, you'll need to override the entire container-interceptors section.


 <interceptor>org.jboss.varia.counter.CounterInterceptor</interceptor>

This can go anywhere in the container-interceptors section, but either the top or the bottom will probably be best for gathering application statistics.
