Assign Load Generators to Groups dialog box

This dialog box enables you to assign one or more load generators—specific, automatch, or elastic—to multiple Vuser groups at once. You can also use this dialog box to remove one or more load generators from multiple Vuser groups at once. For an explanation about the different load generator types, see Load generator types.

To access

  1. In the Performance Test Designer window, click Groups & Workload.

  2. In the Groups pane toolbar, click Assign LG.
Important information

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

User interface elements are described below (unlabeled elements are shown in angle brackets):

UI Elements

Description
Groups pane

Enables you to select Vuser groups to which you can assign or remove load generators.

  • . Enables you to filter the load generators being displayed by name.

  • Name. The name of the Vuser group. To select all the Vuser groups, select the check box next to the column heading.

  • No. of Assigned LGs. The number of load generators assigned to the Vuser group. If a group has load generators assigned to it, click to display this list or to unassign load generators.
Load Generators Pane
Specific tab

Enables you to select load generators from the project's host pool to assign to the Vuser groups in the test, or to remove them from the Vuser groups.

  • . Enables you to filter the information being displayed in grid.

  • Name. The name of the load generator.

  • State. The state of the load generator: Operational, Non-operational.

    Assigned load generators must be operational during runtime.

  • Status. The current status of the load generator.

  • Location. The location of the load generator.

  • Purpose. The purpose of the load generator: Controller, Load Generator, Data Processor, or a combination of these.

    Note: Only the hosts in the pool with at least a Load Generator purpose are displayed.

  • No. of related groups. The number of Vuser groups to which the load generator is assigned. If a load generator has been assigned to groups, you can click to display the related groups list or to unassign groups.
Automatch tab

Enables you to select automatch load generators to assign to Vuser groups in the test, to remove assigned automatch load generators from the Vuser groups, and to add more automatch load generators for the test.

  • . 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 column heading.

  • Properties. The properties by which the automatch load generator is matched up with a specific load generator in the host pool of the project at runtime.

    To specify properties for an automatch load generator, click the corresponding link in this column to open the Load Generator Management dialog box. For details, see Load Generator Management dialog box.

  • No. of related groups. The number of Vuser groups to which the load generator is assigned. If a load generator has been assigned to groups, you can click to display the related groups list or to unassign groups.
Elastic tab

Enables you to select elastic load generators to assign to Vuser groups, to remove elastic load generators assigned to Vuser groups, and to add more elastic load generators for the test. For more on elastic load generators, see Manage elastic hosts.

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

  • Memory/CPU Limit. Specify how much of the available memory (in gigabytes) and CPU resources a container can use during a performance test run.

    Note: If resource limits are set by your Performance Center administrator (in Set up elastic hosts on Windows or Linux containers), you cannot enter values that exceed these limits. If you leave these fields empty, the administrator's limits (if set) are used. If the administrator reduces the project limits to a value below after you have configured your settings, your settings are automatically reset to the new limits.

  • Image Type. Select which load generator image to use for the test. The images assigned to the project are determined by the administrator (in Deploy and manage Docker host images).

  • Name. The name of the elastic load generator. By default, these are named DOCKER1, DOCKER2, and so on.

  • No. of related groups. The number of Vuser groups to which the load generator is assigned. If a load generator has been assigned to groups, you can click to display the related groups list or to unassign groups.
Preview. Opens the Preview window, and displays details of all the load generator assignments (load generator name, type, Vuser group).


Assign

Assigns the selected load generators to the selected Vuser groups.

Note: Available only when at least one unassigned load generator and one group have been selected.


Unassign

Removes the selected load generators from the selected Vuser groups.

Note: Available only when at least one assigned load generator and one group have been selected.
