sri2 [https://community.jboss.org/people/sri2] created the discussion "Interceptor issue" To view the discussion, visit: https://community.jboss.org/message/820493#820493 -------------------------------------------------------------- Hi, I created an interceptor extending from *BasicCustomInterceptor* implementing with *MBean* with simple methods. Initialized/Uninitiazed in *start* and *stop* overrided methods. It accesses these methods when creating and destroying bean. Somehow it has *not* accessed to *visitDistributedExecuteCommand* override method where my logic reside to compute something in distributed mode with numOwners=2. If I override other methods like *visitPutKeyValueCommand* then it accesses. To find the issue, I added some couple of methods by putting print out statement along *return invokeNextInterceptor(ctx, command)* Just for testing purpose. These methods are : 1)//Not Accessed @Override     public Object visitSizeCommand(InvocationContext ctx, SizeCommand command)  throws Throwable {         System.out.println("Inside visitSizeCommand");         return invokeNextInterceptor(ctx, command);            } 2) //Not Accessed @Override public void visitCollection(InvocationContext ctx,  Collection<? extends VisitableCommand> toVisit) throws Throwable {         System.out.println("Inside visitCollection"); //        debug("Collection Size: " + toVisit.size() ); } 3) //Not Accessed @Override public  <V> Object visitDistributedExecuteCommand(InvocationContext ctx, DistributedExecuteCommand<V> command) throws Throwable {         System.out.println("++++++++++++Inside visitDistributedExecuteCommand()");         Object o = invokeNextInterceptor(ctx, command);         // Some logic here         return o;     } 4) // Accessed @Override        public Object visitPutKeyValueCommand(InvocationContext ctx, PutKeyValueCommand cmd) throws Throwable {           System.out.println("Ignoring this call to enforce read-only behavior");           return invokeNextInterceptor(ctx, cmd);        } 5) // Accessed @Override        visitRemoveCommand(InvocationContext ctx, RemoveCommand cmd) throws Throwable {           System.out.println("Visited::::visitRemoveCommand");          return invokeNextInterceptor(ctx, cmd);        } I'm using 5.3.0.Beta1 version with JDK 1.7.0_04. Interceptor added in config file. Testing with PiApproximationDemo and also with SimpleCache ( book, pay and list ) Infinispan book example. Please advice how do I make it access to *visitDistributedExecuteCommand* override method. And also advice how do I access to individual statistics from each node in distributed environment and show it on RHQ monitor/JConsole/JVisualVM by using MBeans or MXBeans.* * Do I have to write a plug in for RHQ? Or Do I have to write purely JMX code? I have to see each node info in addition to  these statistics from URL http://docs.jboss.org/infinispan/5.1/apidocs/jmxComponents.html#Statistics http://docs.jboss.org/infinispan/5.1/apidocs/jmxComponents.html#Statistics. Any input and code examples are appreciated. Thanks in Advance.
