To generate Diagnostics for J2EE & .NET data, you must first install HP Diagnostics.
Before you can use HP Diagnostics with LoadRunner, you need to ensure that you have specified the Diagnostics Server details in LoadRunner. Before you can view Diagnostics for J2EE & .NET data in a particular load test scenario, you need to configure the Diagnostics parameters for that scenario. For more information, see the section on online monitors in the LoadRunner Controller documentation.
Note: To ensure that valid J2EE/.NET diagnostics data is generated during the scenario run, you must manually mark the beginning and end of each transaction in the Vuser script, rather than using automatic transactions.
