## Add a host

Create hosts to run in your performance tests.

To add a host:

1. Prerequisites.

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

   - Check that 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 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 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 | Description
   --- | ---
   Site Management | Sign in to Administration. For details, see Sign in to Admin area. Select Maintenance > Hosts. Select the Hosts tab, and then click the Add Host button .
   Performance testing application | Sign in to Performance testing application. For details, see Sign in. Click the module name or the dropdown arrow in the banner, and select Hosts. Click the Add Host button .
   Site Management | Sign in to Site Management. For details, see Sign in to Site Management. Select the Hosts tab and click the Add Host button .

3. Configure host details.

   1. Configure the new host (not all fields listed below are displayed in the user interface).

      UI Element | Description
      --- | ---
      Host Name | The name or IP address of the new host. Click the host name link to display the host's details in the Host Details view. We recommend giving the host a meaningful name in the Domain\Windows level. Note: Host Name can contain either an FQDN or an IPv4 or IPv6 address. If Host Name is FQDN, the total length of the name (including "[test]") is limited to 93 characters. Do not use the host `[Test]ElasticCont{ID}` 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.
      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.
      Purpose | Select a purpose for the host: Controller , Data Processor , or Load Generator . For details, see Hosts overview 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 unavailable.
      Status | Indicates the 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).
      Type | Displays the host type: 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, the more likelihood a host is 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.
      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 it is, you must select an MI Listener to enable data collection. Note for Site Management only: Hosts are automatically assigned to the Default location and cannot be assigned to any other location.
      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, or in Administration if the location of the host is not over a firewall.
      LR 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 Local System user account is used. If you configure the LoadRunner Agent service with a local or a domain user, it will also set the user under which LoadRunner Agent is running, to that user. Note: When using TruClient 2.0 scripts, we recommend providing a user account other than the System user. For details, see Configure the LoadRunner Agent.
      Enable SSL | Select if you want the load generator host to communicate with the Controller using TLS (formerly SSL). 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.
      Enable IPv6 | Select to use IPv6 for communicating with the load generator host. When selected, the host and the DNS must also be configured with IPv6. Note: When this option is selected, the host connection check fails because the environment does not allow outgoing connections with IPv6. Outgoing connections are allowed for port 80 only.

   2. Click Assign Pools and 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.

   3. Click Assign Host Attributes and 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.

   4. Click Save 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 the Select Columns button (in Site Management, only the ID field is available).

      UI Elements | Description
      --- | ---
      Privacy Type | 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 host is being installed on the host. Rebooting. Indicates that the host is restarting. <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 hosts (including patches), standalone load generators, and upgrades installed on the host machine. Note: While hosts from older installations (up to two versions earlier) are still supported, we recommend upgrading them to the latest version before using them. Earlier versions 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. Click the link to view timeslot details in the Timeslot dialog box. For details, see Timeslot Details Tabs. Note: When running a test and OpenText Enterprise Performance Engineering 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 PostgreSQL Database servers.
      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.

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

   5. 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 displayed items.

## Add elastic hosts to a test

You can run elastic 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 because you no longer need to maintain dedicated load generator machines; you can just provision hosts when you need them.

Elastic host types

You can use the following types of elastic hosts.

Type | Description
--- | ---
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 using Elastic Docker hosts. For details, see Provision Docker hosts automatically. You can also manually configure and assign Dockerized hosts to a performance test from the REST API, or create them from Administration, which users can then assign to tests. For details, see Provision Docker hosts manually.

Add cloud-provisioned hosts to your lab

When adding a host from your test lab, 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.

To add elastic hosts to a test:

1. Prerequisites.

   Make sure that you have defined the network settings for communicating with your cloud provider and 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.

## Configure the LoadRunner Agent

Note: Not available in Site Management or for Linux load generators.

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 sign in to the load generator machine to activate the agent as a process.

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

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.

For details on manually configuring the agent user on each host or standalone load generator machine, see Working with the agent.

To reconfigure the Agent service:

   Note: For TruClient 2.0 scripts, we recommend providing a user other than the System user.

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 (Passed or Failed ).

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

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

4. The following actions require a public key: LR Agent configuration, Reboot, Get Processes, Kill Processes, Get Components(OPLG only), Get OneLG version (OPLG only). For details, see Public keys.

5. Users that will be used for the configuration, must be granted all of the following policies in the Local Security Policy:

   - Create global object

   - Log on as a batch job

   - Log on as a service

   - Access this computer from the network

   - Allow log on locally

   - Impersonate a client after authentication
