Add a host

To add a host from your test lab to LoadRunner Enterprise:

1. Prerequisites

   Ensure the following:

   • Before adding a host, ensure that at least one LoadRunner Enterprise server is in an operational state.

   • The required testing tools are installed on your hosts. Refer to the documentation for your specific testing tools for installation instructions.

   • If a host you are adding is in a remote location, the location must be added in the LoadRunner Enterprise Administration > Maintenance > Hosts > Locations tab. For task details, see Manage host locations.

   • If a host you are adding is over a firewall, the host must communicate with a Performance host through an MI Listener. Make sure that the MI Listener was added in the LoadRunner Enterprise Administration > Maintenance > Hosts > MI Listeners tab. For task details, see Specify MI Listeners.

   • To use cloud-based hosts in a performance test, see Add elastic hosts to a test.

2. Create a new host

   From LoadRunner Enterprise Administration	Log onto LoadRunner Enterprise Administration. For details, see Log onto LoadRunner Enterprise Administration. Select Maintenance > Hosts. Select the Hosts tab, and then click Add Host.
   From LoadRunner Enterprise	Log onto LoadRunner Enterprise. For details, see Log onto LoadRunner Enterprise. Click and select Hosts (under Resources). Click Add Host.
   From From Site Management	Log onto Site Management. For details, see Log onto Site Management. Select the Hosts tab and click Add Host.

3. Configure host details

   1. Configure the new host (not all the fields below are displayed in the LoadRunner Enterprise application):

      UI Element	Description
      Host Name	The name of the new host. Use the IP address or the fully qualified domain name. Click the host name link to display the host's details in the Main Details view. We recommend giving the host a meaningful name in the Domain\Windows level. Note: Do not use the [Test]ElasticCont{ID} host in a test.
      Tenant Name	The name of the tenant to which the host is assigned. Note: Available in Site Management only at the site level; not the tenant level.
      Description	(Optional) A description of the host.
      Purpose	Select a purpose for the host: Controller, Data Processor, or Load Generator. For details, see What are hosts? 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 select OneLG or Unix Load Generator as the host installation option, Load Generator is automatically selected as the purpose for the host and the other options are disabled.
      Source	Displays the host's source: Local if the host exists in your testing lab, or Cloud if the host was provisioned from a cloud provider (if you have existing load generators on the cloud, you must first define network settings as described in Add cloud-provisioned hosts to your lab).
      Priority	Assign a priority (1-9) 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.
      Status	Indicates the current status of the host. You can also change 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. The host machine is not available (there is no information available about the status of the host).
      Location	Select the location of the host. Locations can be defined according to physical areas. The location also determines whether the host is located over a firewall. If so, you need to select an MI Listener that will enable data collection. Note for Site Management only: Hosts are automatically assigned to the Default location and cannot be assigned to any other location.
      Host Installation	Select the installation type of the host:  Windows Host. Indicates that this Windows host can be used for performance purposes (Controller, Load Generator, or Data Processor). Unix Load Generator. Indicates that this Unix host is used as a standalone load generator for performance tests. OneLG. Indicates that this Windows host is used as a standalone load generator for performance tests. Note: The load generator uses TLS (SSL) to communicate with the Controller during runtime only. For non runtime functionality, such as including collating results, the load generator does not use TLS as the communication protocol. Relevant only for load generator hosts located over a firewall.
      MI Listener	If the host is located over a firewall, enter the IP address or name of the MI Listener that enables data collection. Note: Not available in Site Management.
      Enable SSL	Indicates whether the load generator host will communicate with the Controller via TLS (formerly SSL) or not. Note: The load generator uses TLS to communicate with the Controller during runtime only. For non runtime functionality, such as including collating results, the load generator does not use TLS as the communication protocol.
      Assign Pools in LoadRunner Enterprise 2021 R1 and R2 Belongs to Pool in LoadRunner Enterprise 2021	Select pools to assign to the host. Host pools enable you to control which hosts are allocated to which projects. When allocating hosts for a test, the system allocates hosts from the host pool of the project. Hosts must be assigned to at least one pool. Note for Site Management only: Hosts are automatically assigned to a general pool and they cannot be assigned to any other pool.
      Assign Host Attributes in LoadRunner Enterprise 2021 R1 and R2 Host Attributes in LoadRunner Enterprise 2021	Select the system attributes of the host, such as memory, strength, or installed components. For details on defining host attributes, see Customize load generator attributes. Note: Not available in Site Management.

   2. Click Save or OK to add the host to the Hosts grid.

      After adding a host to the Hosts grid, the following additional fields can be displayed by clicking Select Columns (in Site Management, only the ID field is available):

      UI Elements	Description
      Privacy Type (Available in Site Management only)	Indicates whether the host is public or private. Private host. A private host is one that is created by a customer in a load test; only the customer can perform actions on this host. Public host. A public host is any host that is not private, which is created and managed by a Site Administrator.
      ID	The host ID.
      State	The current activity on the host. Idle. Indicates that the host is not being used. Installing. Indicates that a remote installation package 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.
      Version	Lists the version of LoadRunner Enterprise hosts, standalone load generators, and upgrades installed on the host. Note: While hosts from older installations of LoadRunner Enterprise (up to three versions earlier) are still supported and are colored orange, we recommend upgrading them to the current LoadRunner Enterprise version before using them. Versions displayed in red are no longer supported and cannot be used to run tests.
      Active Timeslot ID	The ID of the timeslot for which this host is reserved, and which is now open. Note: When running a test and LoadRunner Enterprise is connected using a PostgreSQL database server, this field is empty if the time zone of the database server’s operating system is not aligned with the time zone in the postgresql.conf file on the database server machine. For details on aligning the time zone, see the PostgreSQL Database servers section in the LoadRunner Enterprise Installation Guide.
      Created By	The user who created the host.
      Created in Project	The project in which the host was created.
      Created on Date	The date and time the host was created.
      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.

      Note: The cloud settings are relevant only for hosts provisioned from a cloud provider.

   3. To display only those hosts that meet the criteria that you define, use the Filter button to select the parameters to include. For details, see Filter.

Add elastic hosts to a test

You can run Dockerized and cloud-based hosts in your performance tests. This automates the testing process by provisioning hosts on demand in response to dynamic workloads and seamlessly adding them to tests.

This is a quick and effective way to port applications across systems and machines, and run them within their own secure environments. This also reduces costs since you no longer need to maintain dedicated load generator machines—just provision hosts when you need to use them.

You can use the following types of elastic hosts:

• Elastic Cloud. You can automatically provision and de-provision load generators from the cloud using Elastic Cloud hosts. For details, see Provision elastic cloud load generators.

• Elastic Docker. You can automatically provision and de-provision load generators from Docker containers. For details, see Configure elastic Dockerized hosts.

  You can also manually configure and assign Dockerized hosts to a performance test from the REST API, or create them from LoadRunner Enterprise Administration, which users can then assign to tests. For details, see Manually configure Dockerized hosts.

Add cloud-provisioned hosts to your lab

When adding a host from your test lab to LoadRunner Enterprise, you can select an existing load generator in the cloud and make it accessible using the port and proxy settings defined in the Cloud Network Settings dialog box.

1. Prerequisites

   Make sure you have defined the network settings for communicating from LoadRunner Enterprise to your cloud provider and with your cloud-based load generators. For details, see Configure cloud network settings.

2. Create a new host.

   When configuring the host, select the following:

   • Purpose. Select Load Generator.

   • Host Installation. Select a standalone load generator: Unix Load Generator or OneLG.

   • Source. Select Cloud.

   For details on creating a host, see Add a host

3. Click Save to save your settings. The port and proxy settings defined in the Cloud Network Settings dialog box are automatically used for communicating with the cloud host.

Upgrade hosts remotely

You can upgrade your LoadRunner Enterprise host machines from LoadRunner Enterprise 202x to the latest LoadRunner Enterprise installation using the Remote Installation feature. For details, see Manage remote installations.

Back to top

Reconfigure the LoadRunner Agent user

The LoadRunner Agent is an application that can be run either as a process (magentproc.exe) or as a service (magentservice.exe). The service is required to enable a load testing script to be run remotely, without having to physically log on to the load generator machine to activate the agent as a process.

Alternatively, you can run Vusers in an interactive RDP session while the agent remains as a service. For details, see Run Vusers in an interactive RDP session.

When run as a service, it is run by a service named LoadRunner Agent Service. (The service is created either during the installation phase, or post-installation from the menu added to the operating system.)

If you encounter issues with TruClient IE Vusers/scripts, you need to reconfigure the agent with user credentials that have the necessary privileges to interact with Windows desktop.

These credentials are used to impersonate all processes that are created to run the different testing scripts on the testing machine. You can create or configure the service in LoadRunner Enterprise Administration from the Hosts tab, or in LoadRunner Enterprise from the Hosts module.

Required security group policies for the user the LoadRunner agent is using to run TruClient IE Vusers/Scripts

By default, the LoadRunner agent user is configured to spawn new processes (mdrv) to impersonate and run under the IUSR_METRO Windows account. If you change the Windows account for the LoadRunner agent user, it will still run under the System account, but it will impersonate the modified/reconfigured user.

For TruClient IE to run successfully, the Windows account used should have the following security group policies enabled:

• Act as part of the operating system (SeTcbPrivilege). Required to log on as a user (authenticate like a user) and gain access to the same resources that the user is authorized to access.

• Replace a process level token (SeAssignPrimaryTokenPrivilege). Allows a parent process to replace the access token that is associated with a child process.

To reconfigure the service in LoadRunner Enterprise Administration or LoadRunner Enterprise:

1. In LoadRunner Enterprise Administration > Maintenance > Hosts, select the hosts in the Hosts grid that you want to reconfigure, and select Maintenance > Configure LoadRunner Agent.

   In LoadRunner Enterprise > Hosts, select the host in the Hosts grid that you want to reconfigure, and click Maintenance > LoadRunner Agent Configuration.

2. In the LoadRunner Agent Configuration dialog box, select Use another account, enter the host account credentials, and click OK.

   

3. The task progress window displays the overall result for each configuration performed on the selected hosts (and restoration task if the configuration fails), including the configuration start and end time, and the configuration status (, ).

   

   Note: If LoadRunner Enterprise is unable to configure the host using the credentials supplied, it automatically attempts to recreate the service using with the LocalSystem user account.

4. For hosts where the change is successful, the agent user configuration data is added to the LoadRunner Agent User column in the Hosts grid.

Run Vusers in an interactive RDP session

You can run Vusers in an interactive RDP session to support testing UI-based protocols.

1. Prerequisites

   The following prerequisites should be applied on the load generators used for running the test in RDP mode.

   Install the Media features component

   The Media Feature pack is required to ensure that FreeRDP has all the necessary codecs to render the remote desktop session (otherwise it will not work). Download the Media Feature Pack from the Microsoft Download Center (if it is not installed by default).

   Enable Media Features

   Perform the following to enable Media Feature on your Windows operating system. Windows Desktop: Select Control Panel > Programs > Programs and Features > Turn Windows features on or off. This opens the list of Windows features. Scroll down and select Media Features. Click OK, and wait until Windows turns on Windows Media Player and other media features. Windows Server: Select Start > Server Manager. In Server Manager, select Manage > Add Roles and Features. Click Next until the Features page appears. In the Features page, select Media Foundation (on Microsoft Windows Server 2008 R2 select Desktop Experience). Assign permissions to allow the agent to be configured in the Remote Desktop Users group.   Open the Group Policy Management editor focused on an appropriate Group Policy object. Navigate to Computer Configuration\Policies\Windows Settings\Security Settings\Local Policies and select the User Rights Assignment node. The agent should be run with user in the Remote Desktop Users group. If Remote Desktop Users group is not listed in the policy, click Add User or Group and add it manually. By default, Remote Desktop Users are allowed to log on through Remote Desktop Services. Set RDP timeout policies We recommend removing the time limits for RDP sessions to prevent sessions being disconnected before the performance test has finished. Open the Local Group Policy Editor for the specific users. Navigate to User Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Session Time Limits. In the right pane, right-click Set time limit for active Remote Desktop Services sessions and click Edit. Select either Not Configured or Disabled. Repeat for the End session when time limits are reached policy.

2. Configure the LoadRunner Agent account

   Select the hosts you want to use in RDP mode and insert your domain user, or local user for non domain joined machines, and password as described in Reconfigure the LoadRunner Agent user above.

3. Configure a performance test with RDP mode

   1. From the LoadRunner Enterprise navigation toolbar, click and select Test Management.

   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, and on the Groups pane toolbar, click LG Management.

   4. Select the load generator types on which you want to enable RDP, and click Enable RDP.

      Tip: We recommend setting RDP mode for specific load generators. If you use it for automatch load generators, you must verify your LoadRunner Agent is configured correctly on all load generators in the pool when the load generators are assigned.

   5. 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).

   6. Click OK, and then save and run the test. The load generator setting with RDP mode is persistent for the specific test only.

   For more details, see Load Generator Management dialog box.

Notes and limitations

• 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.

• If the LoadRunner Agent is running as a process, you must kill the process (magentproc.exe).

• Local accounts on domain machines cannot be used to run the LoadRunner Agent.

• When you log off an RDP user session running the LoadRunner Agent, it will terminate FreeRDP.

• Makes sure you use the default RDP port, 3389, when running Vusers in an interactive RDP session.

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

• RDP mode is not supported with IP Spoofing.

• RDP mode is not supported with Docker.

• When running a test in RDP mode with Citrix Runtime Settings, Citrix client resolution is ignored.

• When running a performance test with Citrix protocol on Microsoft Windows Server 2008 R2, you might get the following popup message:

  

  Solution: You should disable or stop the Interactive Services Detection process.
