LighFish is an opensource Java EE 6 application without any external dependencies which gathers and persists periodically GlassFish's monitoring data. LightFish is deployed on a Java EE 6 application server and usually remotely accesses a "GlassFish Under Stress" instance. The probes (snapshots) are gathered via REST, persisted into a relational DB for post-mortem analysis and pushed to Java FX 2 UI in real time via HTTP.
