    JBoss 7 Memory Probe - know your PermGen

    Matthew Meyer Newbie

      Here is a simple tool that other JBoss developers may find useful. Available at github: https://github.com/mjmeyer/JBoss-AS7-Memory-Probe


      It's a set of REST resources that expose memory stats of the local instance via the new JBoss CLI interfaces. It includes a simple javascript/canvas rendering of % permgen and % heap used as well working examples of how to consume the REST services with monitoring tools like Conky or your own AJAX client.


      I use it to keep an eye on % permgen used on my dev instance and know when I'm getting close to the edge and should bounce the instance. No more bringing the whole JVM down for me...as long as I remember to glance at the graph.
