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.

Specific

Select the load generators for you want to enable terminal services, and click Enable Terminal Services. For details on configuring terminal services, see Enable Terminal Services below.

Note: Properties for specific load generator types are defined by the Performance Center 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.

  • . 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 Terminal Services. For details, see Enable Terminal Services below.
Elastic

Enables you to add additional elastic load generators. To do so, click to create more elastic load generators. Enter the number of load generators in the adjacent box, and click Add. By default, elastic load generator are named DOCKER1, DOCKER2, and so on. For task details, see Assign elastic load generators to a test.

For more on elastic load generators, see Manage elastic load generators.

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.

  • Number 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.

  • Maximum 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 followRun terminal sessions with 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.
