Monitoring in GlassFish v3 Prelude

Today, Sun announced the immediate availability of GlassFishTM Application Server v3 Prelude and its commercially supported counterpart, Sun GlassFish Enterprise Server v3 Prelude.

GlassFish v3 Prelude uses the new lightweight monitoring framework to expose the monitoring data. It moves away from the 'container's collect statistics' theme to 'container's emit events and interested listeners will collect them'. This allows the statistics to be collected in a much cleaner way and makes it more flexible to collect different variations of statistics for the same set of container events. For Prelude we expose the Web Container, Application and JVM statistics, using the asadmin CLI utility and Admin GUI. The Monitoring chapter in Administration Guide, give details of the exhaustive list of statistics that are available in v3 Prelude.

Also It is very easy to extend the monitoring in V3 Prelude, either to emit your own events for a custom component, or to write a new set of listeners thus exposing new statistics for existing container's. Check out here on how to do this.
