Laurent,
Have you considered attaching a SocketAppender to the root category? The
SocketAppender will send its output to a SocketServer. The SocketServer can apply any
logging policy with the LoggingEvents it receives. It can log to multiple files, log
errors here and debugs there, print on the console, do filtering, whatever. The point
is: if you can do it locally then you can do it with a SocketAppender/SocketServer
combination.
The JMSAppender/JMSSink offer the same functionality. Cheers, Ceki
