Distinguishing interleaved log output from different sources

[DELARUELLE Xavier]

Hello Bernd,

We would like to be able at CEA to trace a user request to UNICORE
across the components through the logs.

For the moment we try to distinguish interleaved log lines of one
component's logs (the gateway for instance) from different client
connections. But none of the class name or thread name provided in the
LOG4J configuration enable us to do that.

We have seen that LOG4J provides the MDC class to provide a mapped
diagnostic contexts that intends to distinguish these interleaved log lines:

http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/MDC.html

It would be nice if UNICORE Java components (Gateway, XUUDB and
UNICOREX) can use and define this MDC. Can this be easily added?

Best regards,
Xavier

easy probably, but quite tedious :)
What should go into the context? The only thing that should be
available at all interesting steps is the name (DN) of the current
user in UNICORE/X or the SSL peer in the gateway and XUUDB.

best regards,
Bernd.
