I encountered question how to view the Webservice Monitoring Realtime
Statistic for Glassfish V2 project. This blog lists the steps to configure Webservice Monitoring Realtime Statistic.
-First, please follow the instruction from the technical article Managing and Monitoring Web Services in Project GlassFish to configure your Web service monitoring managing level.
-From admin GUI console, click Common Tasks menu > View Monitoring Data > Call Flow > select to enable Call Flow Monitoring > click to save the changes
For EE version, in addition to the steps above, please start the Derby database.
