# View and manage hosts

The Hosts module enables you to view and manage hosts used for test runs from the Performance testing application.

Tip:

- You can also provision hosts from the cloud for use in performance testing. For details, see Configure a test with cloud-based load generators.

- An administrator can configure hosts from Administration. For details, see Manage hosts.

## View hosts

To view hosts used for test runs, click the Navigation menu and select Hosts.

User interface elements are described below.

UI Elements | Description
--- | ---
ID | The ID of the testing host.
Location | The name of the host location.
Name | The name or IP address of the host. IP addresses in IPv4 and IPv6 format are both supported. For an IP address, you can enter an IP address host name or FQDN. Click the host name link to display additional details about the host and the host tabs. For details, see View or edit host details.
Status | Displays the status of the host and enables you to change the status of a selected 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.
Privacy Type | The privacy type of the host: Public or Private. Private host. A private host is one that is created by a user in a load test. Public host. A public host is any host that is not private, which is created and managed by a Site Administrator.
Runtime State | The current activity on the host. Idle. Indicates that the host is not being used. Installing. Indicates that an upgrade 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.
Purpose | The testing tools available on the host. For example: Controller, Load generator, Data processor. Note: 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 Unix Load Generator or OneLG as the installation option, Load Generator is automatically selected as the purpose for the host and the other options are unavailable.
Installation | 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 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 (SSL) as the communication protocol. Relevant only for load generator hosts located over a firewall.
Priority | A rank assigned to the host (between 1-9). Assigning a higher priority to a host increases the likelihood of the host being 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.
Enable SSL | Indicates whether the load generator host communicates with the Controller through TLS (SSL) or not. 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 (SSL) as the communication protocol. Relevant only for load generator hosts located over a firewall.
Enable IPv6 | Indicates whether IPv6 is used for communicating with the load generator host. When selected, the host must be set with IPv6. For details, see Add a host. Note: The host connection check will fail because the environment does not allow outgoing connections with IPv6. Outgoing connections are only allowed for port 80.
Last Run Time | Displays the date and time that the host was last run in a test. Click the last run time link to open the run page for the selected test.
Active Reservation ID | Displays the timeslot ID. Click the link to open the timeslot for which the host is reserved. Note: When running a test 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.
Attributes | The system attributes of the host. Example: Memory, strength, installed components.
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 Configure the LoadRunner Agent.
MI Listener | The IP address or name of the MI Listener that enables data collection. Relevant only for hosts located over a firewall.
Description | Describes the currently selected host.
OFW Properties | Indicates whether over-firewall settings have been configured for the selected load generator host (Y or N).
Belongs to Pools | The names of the pools that the host is associated with.
Create Date | The date and time the host was created.
Created By | The user who created the host.
Main Details tab | Describes the currently selected host. For user interface details, see Add a host.
Event Logs tab | Displays detailed information about the tasks performed on the selected host, including the event type (an indication of the event's severity: error, warning, or info), a description of any errors, and the category of action where the event occurred.
Installed Product Components tab | Displays a list of the components installed on the host machine, including versions and remote installations or upgrades.
Installed Programs tab | Displays a list of all of the programs installed on the host machine. Details include the version, the publisher of the software, and the date it was installed on the host machine.
Processes tab | Displays information about the processes and resource usage of the selected host, including the percentage of processor time and memory used by the process, and the amount of elapsed time since the process started. Note: For the Processes page to work, IPv6 must be inactive. To deactivate IPv6, open HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\ in the registry Editor, and change the hexadecimal Value data for "DisabledComponents" to "0xFF".
Services tab | Lists all the services on the selected host, including service status (Running or Stopped), and the way the service is set to start up (automatically, manually, or if the service is unavailable).
Check Host Status tab | Displays the checks performed on the selected host, including the areas (Configuration, Connectivity, Installation, Performance) and sub-areas (Processor, Memory, System) that were checked, the expected and actual value resulting from the host check, and the host check status (Passed or Failed).

## Manage hosts

You can perform the following actions on hosts from the Performance testing application.

Action | Description
--- | ---
Add a host | Click Add Host to open the Add Host Dialog box. Configure host details. For details, see Configure host details..
Check host connection | In the Hosts grid, select the hosts you want to check and click the Check Host button . The Check Host window opens, and displays the check host status, the load generator connection status, over firewall settings check, and the start and end times for the check.
Reconfigure hosts | In the Hosts grid, select the hosts that you want to reconfigure and click the Reconfigure Host button . Click Reconfigure to confirm. This resets the Host license, system user (IUSR_METRO), and Communication Security passphrase on the selected hosts.
Configure the LoadRunner Agent | Enables you to reconfigure the LoadRunner Agent to run as a process or as a service for the selected host. For details, see Configure the LoadRunner Agent. Note: Available for Windows hosts that are Operational and in Idle state only.
View pending data processing requests | Select the hosts in the Hosts grid that you want to view the pending data processing requests, and select Maintenance > Data Processor Queue. The Data Processor Queue window opens, and displays the pending data processing requests.
Reboot hosts | Select the hosts in the Hosts grid that you want to restart, and select Maintenance > Reboot Host. Click Reboot to confirm. This remotely restarts the selected host machines. Note: Available only for hosts with Performance purposes. You can only restart Controller and Load Generator hosts when they are in the Idle state. You cannot restart a UNIX load generator host. You cannot restart load generator hosts located over a firewall. To restart Windows OneLG machines from the Performance testing application, you need to add the IUSR_METRO local user and password to the OneLG machine. For details, see this KB article.
Export host data to Excel | Click the Export host data to XLS button to export information displayed in the Hosts grid to an Excel file. Data from the grid is saved to an Excel file and downloaded to the Downloads folder of the client user.
