Testing Hosts Module

This module enables you to view and manage hosts used for test execution.

To access

On the My Performance Center navigation bar, select Resources > Testing Hosts.

Important information

You can provision hosts from the cloud for use in performance testing. For details, see Provision cloud load generators.

Relevant tasks

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

UI Elements


<My Performance Center common UI elements>

For My PC menus and buttons, see Performance Center user interface.

Add Host. Opens the Add Host Dialog box, enabling you to create a testing host. For details, Add a host.
Provision Hosts. Opens the Provision Cloud Hosts dialog box, enabling you to provision hosts. You can choose how many hosts to provision and where the hosts are provisioned, and you can select all necessary host configurations. For details, see Provision cloud load generators.
Delete Host. Deletes the selected host.

Check Host. Opens the Check Host dialog box, enabling you to check connectivity between the selected host and other machines in the system.

Note: Available for hosts in Idle state only.

Reboot Host. Enables you to remotely reboot host machines.


  • You can only reboot Controller and Load Generator hosts when they are in the Idle state.

  • You cannot reboot a UNIX load generator host.

  • Available only for hosts with Performance purposes.

Data Processor Queue. Opens the Data Processor Queue window, enabling you to view the pending data processing requests.

Change Status. Opens the Change Host Status dialog box, enabling you to change the status of a selected host.

The possible statuses are:

  • Operational. The host is working.
  • Non-operational. The host is not working.
  • Unavailable. The host is not available.

Reconfigure Host. Resets the following on the selected host machine:

  • Host license

  • System user (IUSR_METRO)

  • Communication Security passphrase

Note: You can reconfigure only one host at a time.

Provisioning Report. Opens the provisioning report for the selected cloud host. For details, see Provisioning report. This option is disabled if the selected host is not a cloud host.

Configure LoadRunner Agent. Opens the Configure LoadRunner Agent dialog box for the selected host. For details, see Reconfigure the LoadRunner Agent user.

Note: Available for Windows hosts that are Operational and in Idle state only.

Show Cloud Hosts Summary Displays a summary of cloud hosts by status/host state. Click on the number next to a status/host state to filter the Hosts grid by that status/host state.

<Quick Views>


Lists predefined filters for the testing hosts grid. The following quick views are available:

  • All Hosts.

  • Cloud Load Generators.

  • Local Hosts.

  • Custom. To customize the columns displayed in the grid, in the upper right corner, click Select Columns .

Add Filter

Enables you to filter the information being displayed in the testing hosts grid. Click the drop-down arrow to apply a filter.

ID The ID of the testing host.

The testing host's source:

  • Local. The host exists in your testing lab.
  • Cloud. The host was provisioned from a cloud provider.
Name The name or IP address of the host.

The testing tools available on the host. For example:  Controller, Load generator, Data processor.


  • If the host machine is located over a firewall, or is a UNIX machine, it cannot function as a Controller or Data processor.

  • If you selected Windows Standalone LG or Unix Load Generator as the installation option, Load Generator is automatically selected as the purpose for the host and the other options are disabled.


The status of the host. The possible statuses are:

  • Operational. The host machine is up and running.

  • Non-operational. The host machine is down.

  • Unavailable. There is no information available about the status of the host.


The current activity on the host.

Idle. Indicates that the host is not being used.

Installing. Indicates that a patch is being installed on the host.

Rebooting. Indicates that the host is rebooting.

<Run states>. Indicates the host state during a performance test run.

<Data processing states>. Indicates the state of the host during a data processing task.

<Provisioning states>. Indicates the provisioning status of a cloud host. Host State changes to idle once the host is provisioned.

Location The name of the host location.

The system attributes of the host.

Example: Memory, strength, installed components.

Tip: You can customize the host attributes in Lab Management. For details, see Customizing Project Entities in the ALM Lab Management Guide.


A rank assigned to the host. The higher the priority you give the host, the more likely the host will be allocated to a test. There are a number of criteria to consider when assigning priority. The main considerations are whether the host is a dedicated machine or a shared resource, and the type of hardware installed on the machine.

Privacy Type

The privacy type of the host. You can modify all hosts in Lab Management, including private hosts. In ALM, you can only create and modify private hosts within the project's pool.

Active Timeslot ID The ID of the timeslot for which this host is reserved, and which is now open.
LoadRunner Agent User Displays the domain and user name of the agent that enables communication between the Controller, Load Generators, and MI Listeners. If the field is empty, the default LocalSystem user account is being used. For details, see Reconfigure the LoadRunner Agent user.
MI Listener

The IP address or name of the MI Listener that enables data collection. Relevant only for hosts located over a firewall.

Cloud Account

The name of the cloud account from which the host was provisioned.

Cloud Host Identifier

A unique ID for the host assigned by the cloud provider.

Cloud Image

The machine image applied to the cloud host.

Cloud Instance Type

The hardware specs of the cloud host.

Cloud Region

The region from which a cloud host was provisioned.

Cloud Request Id

The cloud provider's ID for a single provision request. A provision request includes all requested batches of hosts. Each batch has its own Cloud Request Item ID.

Tip: You can filter by Cloud Request ID to see all hosts that were provisioned in a single provision request.

Available in: Cloud Load Generators

Cloud Template

The host template used to provision the host. Changing a host template does not affect existing hosts that were provisioned from the template.

Available in: Cloud Load Generators

Runtime State

Indicates the host state during a performance test run.

Description tab Describes the currently selected host.
Event Log tab Displays detailed information about the tasks performed on the selected host, the action status, and a description of any errors.
Installed PC Components tab Displays a list of the Performance Center components installed on the host machine, including versions and patches.
