Configuring J2EE Diagnostics on the Client Machine - LoadRunner

To monitor J2EE transactions, you must connect between the application server (with the probe) and the mediator. The application server and the Controller connect via the mediator. The settings that you configure are per scenario. All scripts in the scenario will run under the same diagnostics configuration.

Note: Ensure that the application server has finished launching before attempting to connect the Controller to the Probe/Mediator.

Setting Up the J2EE Diagnostics Module

You configure J2EE diagnostics settings using the J2EE Transaction Breakdown dialog box. You can then enable J2EE transaction breakdown using the Diagnostics Distribution dialog box.

To set up the J2EE Diagnostics module:
