Log4JMonitor is a Java application that consists mainly of a frame listing all the Log4J messages/events received by another application which produces such events (using Apache's Log4J engine) and sends them to Log4JMonitor through the network. Log4JMonitor acts as a server socket for the Lo4J messages which need to be sent to such a server by implementation. Log4JMonitor is based on Apache's demonstration of a SocketServer/SocketAppender pair, programmed by Oliver Burn.
