HP Diagnostics and LoadRunner Integration

Advertisement:

The HP Diagnostics integration with LoadRunner allows you to monitor and analyze the performance of Java 2 Enterprise Edition (J2EE), .NET-connected, SAP, Oracle, and other complex environments.


Specifying the Diagnostics Server Details: The first time you use LoadRunner to capture J2EE or .NET diagnostics data, you need to identify the machine on which the Diagnostics Server in Commander mode is running, and the port that it is using for communication with LoadRunner. You must update this information if you want to integrate with a different Diagnostics Server in Commander mode, or if you change the port it is using.

To update the LoadRunner configuration settings for HP Diagnostics:

1. Select Start > Programs > HP LoadRunner > LoadRunner to open the LoadRunner launcher window.
2. From the LoadRunner launcher window menu, select Configuration > Diagnostics for J2EE/.NET Setup to open the Diagnostics for J2EE/.NET Setup dialog box. Enter the details for the Diagnostics Server in Commander mode.
3. Click Test to verify that you entered the correct information for the Diagnostics Server in Commander mode and that there is connectivity between the Diagnostics Server in Commander mode and LoadRunner. Click OK to complete the configuration process.

Configure LoadRunner Scenarios to use HP Diagnostics

1. Before configuring your scenario for Diagnostics, ensure that the application server that you are monitoring has been started.
2. In the Controller, open the relevant load test scenario (FIle > Open) or create a new scenario (File > New).
3. Select Diagnostics > Configuration to open the Diagnostics Distribution dialog box.
4. Set the percentage of Vusers to participate in the HP Diagnostics (J2EE/.NET Diagnostics) monitoring. The maximum percentage of Vusers for which HP Diagnostics (J2EE/.NET Diagnostics) data can be collected is 100%, unless you have enabled other types of diagnostics. In this case, the percentage of Vuser participation in HP Diagnostics (J2EE/.NET Diagnostics) cannot exceed the maximum of any of the other types of diagnostics that you enabled.
5. In the Online & Offline Diagnostics section of the Diagnostics Distribution dialog box, next to J2EE/.NET Diagnostics, click Configure. The J2EE/.NET Diagnostics Configuration dialog box opens.
6. Select Enable J2EE/.NET Diagnostics
7. In the Select probes list, select the probes to be included in your load test scenario.
8. If the Diagnostics Server (or a Diagnostics Server in Mediator mode in a distributed environment) is located behind a firewall, select There is a firewall between the mediator and the Controller, and enter the name of the MI listener server in the MI listener server box. If there is a firewall between the LoadRunner Controller and the Diagnostics Server involved in a load test, you must configure the Controller and the Diagnostics Server to use the MI Listener to enable the transfer of the offline analysis file.
9. To capture a percentage of server requests which occur outside the context of any Vuser transaction select Monitor server requests.
10. To investigate any issues that you have with the connections between the Diagnostics components, click the Troubleshoot Diagnostics for J2EE/.NET connectivity link. This will open the HP Diagnostics System Health Monitor in a new browser window.

During a LoadRunner load test scenario, you can view HP Diagnostics data for the whole scenario or you can drill down to HP Diagnostics data from a particular transaction. After you have run your scenario, you can use HP LoadRunner Analysis to analyze offline Diagnostics data generated during the scenario.
