The JavaCategory statistical category must be specified in a stat type’s definition to use statistical definitions residing in a Stat Server Java Extension (SSJE). When loaded, each SSJE passes its own statistical definitions to Stat Server availing them to Stat Server clients. These stat types can be real-time or historical and, unlike regular stat types, are dynamic in nature. This means that they are enabled only if the corresponding SSJE is loaded.
The Solution Reporting Templates book of the Reporting Technical Reference series describes stat types provided in the 7.x and 8.x releases of the OCC and Multimedia SSJEs.
The JavaCategory is not supported when Stat Server is operating in restricted cluster mode.
