Hi, The "vector of timestamps" alg. is one that can determine the order of causal depending events. And I think it is enough for debugging. When debugging, u don't mind about events tha are not related to each other. What u want to know is if a set of events on each node by a global time is consistent.
Basicly, u can use a VT (vector timestamp) layer on your system messages and an "distributed snapshot" for determining a global state. .- Chow/Johnson: sections 9.2-9.4 .- Colouris/Dollimore/Kindberg: sections 10.4-10.7 .- Yang/Marsland (Eds): Global States and Time in Distributed Systems, IEEE Computer Society Press .

It will listen to LoggingEvent from all the machines you wish and dump into a file. It will be less expensive on network resources than JMS and it's easier to setup. On the other hand, I think it's less likely that logging events will be lost with JMS. My 2c, Juan Pablo Lorandi Chief Software Architect Code Foundry Ltd.
