One of the areas that has been improved significantly in GlassFish v3 is monitoring -see Prashanth'sFunctionality Overview.Most of the functionality is in the core product but some added value features will be part of thenext version of theGlassFish Enterprise Manageravailable through Sun's commercialSun GlassFish Portfolio.

Two recent posts by Sreeni explain how to use the new functionality toEnable/disable monitoring and attach Btrace-agentand toCreate pluggable container-monitoring elements.The new monitoring functionality can also be used with JRuby,as Arun describes inHow to monitor a Rails app using asadmin, JavaScript, jConsole, REST.

We are all looking forward towardsGlassFish v3 FCS!
