Integrate Network Virtualization into a performance test

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

  1. Prerequisites

    • Make sure that you have Network Virtualization installed on the following machines: the Performance Center server, the load generators, the Controller.

      For details on Network Virtualization, see the Network Virtualization product page.

    • Make sure that you have a properly designed performance test. For details, see 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 and 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, set the Virtual Location Mode to On.

    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 details, see LoadRunner & Performance Center Network Virtualization Help.

    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. In the Virtual Location Editor dialog box, 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.

  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. Define the load generator settings

    1. In Performance Test Designer window click Groups & Workload. On the Groups pane toolbar, click Assign LG. The Assign Load Generators dialog box opens. For user interface details, see Assign Load Generators to Groups dialog box.

    2. In the Groups column, select the Vuser groups to use in the test.

    3. In the Load Generators column, select one or more load generators from the Specific or Automatch tabs.

      Note: Network Virtualization is not supported when using elastic hosts.

      To assign additional automatch load generators, click , enter the number of load generators in the adjacent box, and click Add.

      To define settings for automatch load generators, click the Properties link to open the Load Generator Management dialog box. Select the load generators for which you want to define the same settings, and select the location and host attributes. For user interface details, see Load Generator Management dialog box.

    4. After you have selected the load generators to assign to the groups, click Assign, and then click OK.

    5. In the Default Virtual Location 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 load generator connected over a firewall - Add monitors manually

    If a load generator is connected over a firewall, add monitors manually using the Monitor Over Firewall component. For details, see Monitor over Firewall (MOFW) in the LoadRunner Help Center.

  9. Run the performance test

    Run the test to check its performance. For more details on running a performance test, see 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 (online screen). For more details on viewing results in Analysis, see the LoadRunner Help Center.
