It is different from previous version as it has become light by using light weight probe based architecture. This enables us to perform ad hoc monitoring in production with minimal impact. One does not have to restart the server, just start monitoring the specific issue at hand, very similar to DTrace on Solaris. In fact, GlassFish v3 monitoring exposes monitoring probes as DTrace probes on Solaris and Mac.This combined with native dtrace probes of Solaris provide an opportunity to monitor attributes which was not possible earlier. Don't worry, for non-solaris platforms, we have client-scripting. Determine the probes you want to monitor and write a java script using these probes, deploy the script to server and start receiving monitoring events. Isn't that Cool!
