Are there any other classes I should be logging? Use the information Mark sent. That worked for me with one minor change. I had to set this level to FINER. org.apache.catalina.tribes.MESSAGES.level = FINER With this, I see messages like this in the logs: 19-Sep-2013 09:02:07.930 FINER [Tribes-Task-Receiver-3] org.apache.catalina.tribes.transport.nio.NioReplicationTask.drainChannel NioReplicationThread - Received msg:UniqueId{126, 49, 93, 96, -109, -4, 64, -43, -70, 66, -70, -118, 104, 59, 39, 6} at 2013-09-19 09:02:07.929 19-Sep-2013 09:02:07.930 FINER [Tribes-Task-Receiver-3] org.apache.catalina.tribes.group.ChannelCoordinator.messageReceived ChannelCoordinator - Received msg:UniqueId{126, 49, 93, 96, -109, -4, 64, -43, -70, 66, -70, -118, 104, 59, 39, 6} at 2013-09-19 09:02:07.93 from tcp://{192, 168, 0, 6}:4000 19-Sep-2013 09:02:07.930 FINER [Tribes-Task-Receiver-3] org.apache.catalina.tribes.group.GroupChannel.messageReceived GroupChannel - Received msg:UniqueId{126, 49, 93, 96, -109, -4, 64, -43, -70, 66, -70, -118, 104, 59, 39, 6} at 2013-09-19 09:02:07.93 from tcp://{192, 168, 0, 6}:4000 19-Sep-2013 09:02:07.931 FINER [Tribes-Task-Receiver-3] org.apache.catalina.tribes.group.GroupChannel.messageReceived GroupChannel - Receive Message:UniqueId{126, 49, 93, 96, -109, -4, 64, -43, -70, 66, -70, -118, 104, 59, 39, 6} is SESSION-DELTA#localhost#/test#20845635BA34BD2304B8574809161BFC.tc-runtime-1 19-Sep-2013 09:02:07.931 FINER [Tribes-Task-Receiver-3] org.apache.catalina.tribes.group.GroupChannel.messageReceived GroupChannel delivered[true] id:UniqueId{126, 49, 93, 96, -109, -4, 64, -43, -70, 66, -70, -118, 104, 59, 39, 6} Dan > > Thanks, > Nick --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
