Load Generator Management dialog box

This topic describes how to manage the different load generators type that are available to use in your performance test. For details on the load generator types, see Load generator types.

To access:

  1. From the LoadRunner Enterprise navigation toolbar, click and select Test Management (under Testing).

  2. Select a performance test in the test management tree and click Edit Test.

  3. In the Performance Test Designer window, click Groups and Workload.

  4. On the Groups pane toolbar, click More > LG Management.

Note: To select multiple load generators, click a row and drag the mouse to highlight the load generators you want to select. To select all load generators in the column, select the check box next to the Name column heading, or press CTRL + A.

User interface:

User interface elements are described below:

UI Elements

Description

Copy/Paste load generator settings. Enables you to copy load generator properties from the selected automatch load generator, and paste them to other automatch load generators.

Load Generator Type tab
Specific

Select the load generators for which you want to enable remote desktop sessions or enable terminal services, and click Enable RDP or Enable Terminal Services. For details, see RDP settings and Terminal Services settings below.

Note: Properties for specific load generator types are defined by the LoadRunner Enterprise administrator, and are read-only.

Automatch

Enables you to define properties for automatch load generators. Properties include a location, and other host attributes. At runtime, a specific load generator in the host pool of the project matching these properties is assigned to the Vuser group.

When you select one or more automatch load generators, all the load generator details are displayed in the right pane.

  • Add LGs. Click to add more automatch load generators for the test. Enter the number of load generators in the adjacent box, and click Add.

  • Name. The name of the automatch load generator. By default, these are named LG1, LG2, and so on. To select all load generators in the list, select the check box next to the Name heading.

  • Location. Choose a load generator location for the selected load generators.

  • Host Attributes. You can customize the list of attributes. For details, see Customize load generator attributes.

     Example:

    You want a Vuser group to use a load generator that is located in London and has medium strength and memory. Under Location, select London, and in the Host Attributes list, select Host memory: Medium and Host strength: Medium. At runtime, the system tries to assign a specific load generator with these properties to the Vuser group.

  • Enable RDP. For details, see Enable RDP below.
  • Enable Terminal Services. For details, see Terminal Services settings below.

Elastic Cloud

Enables you to add or remove elastic cloud load generators.

  • . Opens the Add New Elastic Cloud dialog box, enabling you to add more cloud load generators for the test. Select the load generators and the number of each that you want to add. You can filter the list of load generators displayed in the grid by account, location, size, and/or operating system.

    Click Add to add the selected load generators and close the dialog box, or Add & Another to add and keep the dialog box open enabling you to add additional cloud load generators.

  • . Click to delete the selected cloud load generators from the list.

  • Name. By default, cloud load generators are named CLOUD1, CLOUD2, and so on. For task details, see Assign elastic hosts to a test.

  • Template Name. Name used to identify the template.

  • OS. Operating system of the cloud load generator.

  • Location. Geographic location in which the cloud load generator is provisioned.

  • Account. Cloud provider from which the load generator is provisioned (Amazon Web Services or Microsoft Azure).

  • Size. The hardware configuration of the machine to be provisioned. This will impact the storage and memory.

For more on elastic cloud load generators, see Provision elastic cloud load generators.

Elastic Docker

Enables you to add additional elastic dockerized load generators. To do so, click to create more dockerized load generators. Enter the number of load generators in the adjacent box, and click Add.

Name. By default, dockerized load generators are named DOCKER1, DOCKER2, and so on. For task details, see Assign elastic hosts to a test.

For more on elastic dockerized load generators, see Configure elastic dockerized hosts.

RDP settings
Enable RDP

To support GUI testing, you can run Vusers in an interactive RDP session. Select this option to enable remote desktop sessions for the selected specific or automatch load generator types. For task details, see Run Vusers in an interactive RDP session.

Note:

  • Interactive RDP mode is not supported when a LoadRunner Enterprise host is used simultaneously as a Controller and load generator.

  • RDP mode is not supported for a local system user account. While a performance test with a system account will run for a load generator set to RDP mode, it will not open an interactive RDP session.

Color depth and Resolution Select the required color depth and resolution to be used to create the RDP session on the hosts running the script (the graphic card of the hosts running the script will determine the default color depth and resolution if it does not support the selected one).
Terminal Services settings

Enable Terminal Services

Enables you to configure terminal services sessions for the selected specific or automatch load generator types. For task details, see Configure terminal sessions.

No. of Terminal Services to open on Load Generator

Enter the number of terminals in your performance test.

Note: You must open a terminal session for each terminal on which you want to run Vusers during the performance test.

Max. number of Vusers to run in a Terminal Service

Enter the maximum number of Vusers that you want to run in a terminal session.

Note: The maximum number of Vusers depends on the Vuser type used in the script. For GUI Vusers, the maximum is one Vuser for each terminal session.

Create new session

Enables the Controller to launch terminal sessions automatically using the Remote Desktop Connection.

  • When choosing this option (the default setting) you must specify the credentials required for automatic login: User Name, Password, and Domain.

    If you are using a custom user account, make sure you follow Run terminal sessions with a custom user account.

  • Bit Level. You can also select the color depth of the session (15, 16, 24, or 32-bit level).

Connect to existing session

Enables a connection to an existing (open) terminal session. If you select this option, you must open a terminal client session manually for each terminal that you want to run Vusers on during the test run.
