How to Integrate Network Virtualization into a Performance Test

This following describes how to integrate Network Virtualization into your performance test and how to view the metrics in Analysis.

To learn more about Network Virtualization, see Network Virtualization Overview.

1. Prerequisites

   • Make sure that you have HP Network Virtualization installed on the following machines:

     • the Performance Center server

     • the load generators

     • the Controller

     For more information on HP Network Virtualization, see the HP Network Virtualization product page.

   • Make sure that you have a properly designed performance test. For more information, see How to Define a Performance Test Workload.

2. Open network virtualization

   1. In the Performance Test Designer window, click Groups & Workload. For user interface details, see Performance Test Designer > Groups & Workload.

   2. Click . The Virtual Location Editor dialog box opens. For user interface details, see Virtual Location Editor Dialog Box.
3. Enable network virtualization and choose a virtualization method

   1. In the Virtual Location Editor dialog box, enable the Virtual Location Mode.

   2. Select Per Group or Per Load Generator.

      Use the default Per Group to perform network virtualization per Vuser group. This option enables you to emulate multiple virtual locations on the same load generator. It makes it easier to switch between load generators used in your performance test.

      Use Per Load Generator to perform network virtualization per load generator, where each machine can only emulate a single location.

4. Define global settings

   1. Click Common Settings. Opens the Virtual Location Test Level Settings page, enabling you to apply the settings to all virtual locations that are included in the test. For more details, see the HP Network Virtualization User Guide.

   2. In Enable Packet Capture, define packet capture settings.

   3. In Exclude these IP's, specify any machines that you may want to exclude from network virtualization for all locations. For details on which machines to exclude, see Excluding Machines from Network Virtualization.

5. Add virtual locations

   1. Click the New Virtual Location button. Type a location name.

      Use the ANSI standard format. You cannot use the following characters: \ / : “ ? ‘ < > | * % ^ , ! { } ( ) ; = #

   2. Click OK. The Select Virtual Location Definition Method page opens, enabling you to configure the virtual location. For more details, see the HP Network Virtualization User Guide.

6. For network virtualization per Group - Define the settings for each group

   1. In the Performance Test Designer window click Groups & Workload, under the Virtual Location column, click the Select virtual location link. The Virtual Location dialog box opens.

   2. Select a virtual location.

7. For network virtualization per Load Generator - Define the settings for each load generator

   1. In Performance Test Designer window click Groups & Workload, in the LG Distribution box, select Assign manually.

      Note: For more details on LG distribution methods, see Performance Test Designer > Groups & Workload.

   2. Under the Load Generator column, click the Select Load Generator link. The Select Load Generators dialog box opens. For user interface details, see Select Load Generators Dialog Box .

   3. Select the Automatch or Specific tab. Select one or more load generators.

   4. Under the Virtual Locations column, click the Select Virtual Location link for each selected load generator. The Select Virtual Location dialog box opens. Select a virtual location.

8. For network virtualization per Load Generator - Define the same settings for all load generators

   1. In the Performance Test Designer window click Groups & Workload, in the LG Distribution box,select Assign all to each group.

   2. In the LG box, specify the number of automatch load generators for the test.

   3. Click the Configure Load Generators Properties button . The Automatch Load Generators Properties dialog box opens. For user interface details, see Automatch Load Generators Properties Dialog Box.

9. Run the performance test

   Run the test to check its performance. For more details on running a performance test, see How to Manage a Performance Test Run.

10. View the graphs

    Network virtualization metrics are automatically collected during the performance test run.You can view all the network virtualization metrics in the Performance Test Run Page or the LoadRunner Analysis.

    For more details on the Performance Test Run page, see Performance Test Run Page. For more details on viewing results in Analysis, see the HPE LoadRunner Analysis User Guide.
