hawtio has lots of plugins such as: a git-based Dashboard and Wiki, logs, health, JMX, OSGi, Apache ActiveMQ, Apache Camel, Apache OpenEJB, Apache Tomcat, Jetty, JBoss and Fuse Fabric
You can dynamically extend hawtio with your own plugins or automatically discover plugins inside the JVM.
The only server side dependency (other than the static HTML/CSS/JS/images) is the excellent Jolokia library which has small footprint (around 300Kb) and is available as a JVM agent, or comes embedded as a servlet inside the hawtio-default.war or can be deployed as an OSGi bundle.
We love contributions!
