Hi!

If the loggers are configured to log to files, all your output will show up
in the ".log" files in the "log" directory.
If the loggers are configured to log to console, all your output will show
up in the ".out" files in the "log" directory.

There is no functionality built in to take log output and transfer it to
the submitting client's console.

Greetings,
Stephan
