There's nothing simple, no. Nothing that aggregates data together from different calls. If you're using EJB2 and have log4j available on the client side, on the client side you can enable TRACE logging of the org.jboss.invocation package; you'll get info there on what node was chosen for each call. For HA-JNDI, enable TRACE for org.jboss.ha.framework.interfaces.HARMIClient. For EJB3, it would be org.jboss.remoting. Those categories are probably a bit too broad, but once you see what logs what you can target them a bit more.
