As I wrote before, you need to create a *sampler* to connect to the queue. The sampler will generate a sample result which can be displayed in any of the Listeners. > If I look at the ViewResultsFullVisualizer.java file which is "View Results > Tree" Listener > > GUI class signature: *public* *class* *JMeterCustomListenerGui* > *extends*AbstractVisualizer > *implements* NoThreadClone > Listener class signature: *public* *class* JMeterCustomListener > *implements*NoThreadClone > In which GUI method will allow me to just to create one listener instead of > creating multiples.
