This topic describes how to add on-premises load generators to your load test.

Add and edit on-premises load generators

On-premises load generators are ideal for running load tests on applications that cannot be accessed from behind your firewall.

Only load generators that were added to the project's assets are available. For details, see Load generator management.

To create, edit, or delete a load generator, select Assets > Load Generators and do one of the following:

Action How to
  1. Click to open the New Load Generator dialog box.
  2. Give the new load generator a meaningful name and description.

  3. Select the relevant operating system.

  4. Set the maximum number of Vusers for each supported protocol. Default values are displayed.

  5. Click Save.

    A key is generated for the load generator and is displayed in the details on the right.


You can edit on-premises load generator settings to rename it, enable or disable Vuser log collection, or adjust the number of maximum Vusers per protocol.

  1. In Assets > Load Generators, select one load generator.
  2. Click .
  3. Update the load generator's details:

    • Toggle the Enable Vuser Logs Collection toggle to enable or disable the collection of Vuser logs during a load test. This option is only available if Collect Vuser logs from on-premises load generators is checked in the General options. For details, see Data and logs.

    • Adjust the maximum number of Vuser for each protocol. These settings may be relevant if you experience an overload on your on-premises load generator, or if alerts were issued. For details, see LG alerts.


Click to delete the selected load generators. The deleted load generators are detached from all load tests in which they were included, and are then deleted entirely.

Note: The Delete option is only available when Tenant Management is not enabled for your tenant.


Click to remove the selected load generators from the current project. The load generators are detached from all load tests in the current project in which they are included, and are then removed from the current project.

The removed load generators are still available for other projects. You can re-add them back to the current project from the Tenant Management area.

Note: The Remove option is only available when Tenant Management is enabled for your tenant.


Click to update the view of the on-premises load generator grid. This is useful for checking a load generator's current connectivity status. For example, if a load generator was temporarily unavailable, click Refresh and view the Status column to check its availability.
