Ever wanted an easy tool for persisting your App Server's monitoring data with no external dependencies.  Well if you use GlassFish you're in luck, because Adam Bien has created a cool tool for that app server called LightFish that will store your monitoring data up in a RDBMS.  It then pushes that data to a JavaFX 2 UI in real-time to visualize this data.

Here's a video intro and the features Adam lists:


Features / Monitoring:
    Threads And Memory:

    Heap Size, Thread Count, Peak Thread Count

    Transactions:

    Commits and Rollbacks

    "Paranormal Activity" :-)

    Queued Connections, Errors and Busy Thread Count

    HTTP Sessions

    Active and Expired Sessions

    JDBC Pools

    Free and used connections, potential connection leaks, and the Length of the wait queue

    --Adam Bien

DevOps practitioners have known that #monitoringsucks for a while now, and hopefully this tool for the app server part of your stack is a step in the right direction.  Try it out now.
