JON is a lightweight performance and server monitoring tool offered by the JBoss community. JON agents could be configured to discover JBoss servers such as JBoss Web and JBoss EAP in order to visually monitor the performance of the various applications. JON could monitor the classes, memory usage, CPU usage and so on.
Although JON could be used to run scripts fo automation of application releases, it would not be the best tool for that. Especially when there are continious integration tools such as Hudson. The JON command line interface (CLI) tool allows to run javascripts to communicate with the JBoss Server and release web archives (WAR), enterprise archives (EAR) and so on.
