Remko Popma commented on LOG4J2-665:
------------------------------------
Perhaps there is a misunderstanding: the JMX Client GUI is not intended to
remotely monitor a log file, it is just to remotely view (and perhaps edit)
your logging configuration.
Does the LoggerContext:... tab show the contents of your configuration file? If
so, the JMX GUI is working correctly.
Perhaps Apache Chainsaw is closer to what you are looking for:
