Set the default maximum packet list buffer size for each load generator

You can specify that when a LoadRunner Professional scenario or LoadRunner Enterprise test runs, that the network packets that are transmitted across the network are captured, and stored in a buffer for future analysis. The NV Common Settings let you specify the maximum size of the packet list buffer that is available for each load generator in a scenario or a test. For details, see Define virtual location test level settings. You can specify the default maximum packet list buffer size that is applied to each new scenario or test.

Packet capture is configured within a virtual location. One of the packet capture settings you configure in a virtual location is the maximum size of the packet list. For details, see Define virtual location test level settings.

When using the option to generate NV Insights reports in VuGen, the maximum packet list size is defined by the PacketListMaxSizeMB property, in the NV configuration file. You can modify the maximum buffer size as described below.

To modify the default maximum packet list buffer size:

  1. Stop all network virtualization tests that are currently running.

  2. Navigate to the following folder: <installation_folder>\conf.

    By default, <installation_folder> is C:\Program Files\OpenText\NV\.

  3. Open the file userConfiguration.xml file in a text editor.

  4. Locate the PacketListMaxSizeMB property, and set it to the required value.

    The permitted range is 10 - 1,000 MB.

  5. Save the file.
  6. Restart the Network Virtualization service (NVWatchDogService).
