Benchmark Factory Agents reside on each physical client machine and spawn multiple virtual-user sessions. Each Agent generates an information screen with tabs that contain a variety of Agent information. Benchmark Factory can control hundreds of Agent machines.
Each Agent can simulate up to 1500 virtual users, depending upon hardware and test configuration. Virtual users simulate the load against the system-under-test. Each virtual user is a separate thread, acting independently of the other virtual users, with its own connection to the system-under-test. Each virtual user tracks its own statistics that includes transaction times and the number of times a transaction executes.
The Agents view or pane in the main Benchmark Factory window displays the status of the agents currently running.
To open the Benchmark Factory Agent dialog, go to Program Files\Quest Software\Benchmark Factory <version>\bin and double-click Agent.exe.
The Benchmark Factory Agent dialog provides the follow tabs:
You can use this page of the Settings dialog to:
To specify default Agent settings
Select Agent. Review the following for additional information:
Setup New User Agent | Click to setup a new agent. |
List of agents |
Specify default settings. Select the agent machines and specify the number of agents. These default settings are used when you create a new job. If you do not select a default agent, the local agent is automatically selected when you create a new job in the New Job wizard. Note: When you run a job using one or more local agents, if Agent utilization of resources on the local machine is too high, errors could occur. |
Remove | Click to remove the selected agent. |
Verify Selected Agent | Verifies that selected agent starts and communicates with console. |
Error Handling |
Stop job when agent cannot be started/connected—Cancels job if agent does not start or connection is lost. Do not select this option if you want to run a job using multiple agents AND you want the job to run even if one or more agents do not start. |
Agent communication timeout | Specify timeout duration in seconds. |
Agent refresh interval | Specify how often each agent should refresh its status. |

Tips:
You can install agents to remote computers from your Benchmark Factory console. You must be able to connect to the remote machine.
To install remote agents from the console
Enter the connection information for the remote machine. Review the following for additional information:
IP Address / Name | Enter the IP address or name of the remote machine. |
User Name |
Enter the user name to use to connect. Note: Only accounts in the Administrators group on the remote machine can install or launch remote Agents. If in a domain, connect using a domain account in the Administrators group. |
Password |
Enter the password to use to connect. |
Use Windows session credentials |
Select to use Windows credentials. |
# of Agents | Specify the number of agents to deploy on this machine. |
In the Installer field, browse to and select the Benchmark Factory installer.
Note: The Installer can be located on your local machine or on the remote machine.
Click OK. The installer installs the agent component on the remote machine.
Note: If the agent fails to install, you may need to configure the firewall or attempt one of the troubleshooting techniques. See Configure Firewall for Remote Agent Install/Start-Up.
In order to install remote agents and allow communication with remote agents after installation, you may need to configure the firewall on the console machine and on each agent machine. See Configure Firewall for Remote Agent Install/Start-Up to learn more.
If you configure the firewall and then encounter an error when attempting to install a remote agent, find some troubleshooting techniques here: Troubleshooting.
You can install agents on multiple agent machines in order to run tests using multiple agents. To configure Benchmark Factory with multiple agents you must:
For best results, install remote agents through your Benchmark Factory console. You can install remote agents from the Settings dialog (Edit | Settings | Agent) or from the Agent page of the New/Edit Job Wizard. See Install Remote Agents for more information.
You can also install agents manually on the agent machine. If you do, you must configure the agent on the agent machine (see below). Then, in your local Benchmark Factory, you must set up the agent to register it with the console. See Agent Settings for more information.
If you set up an agent machine by installing Benchmark Factory manually, you must configure the agent on the agent machine.
Each Benchmark Factory Agent must be configured with the address of the Benchmark Factory Console. Each Agent sends load testing results back to the Benchmark Factory Console.
If you use only the agent installed locally on the console machine, make sure your local agent is configured with the IP address (name) of your local machine.
To configure Benchmark Factory Agents
In Machine Name/IP field, enter the address of the Benchmark Factory console machine. In the Console Port field, enter the port for the Benchmark Factory console.
To run a job using multiple agent machines, after the agents are installed and configured, you must set up (or add) each remote agent to the Benchmark Factory console.
To run a job with multiple agents
Note: When you run a job using one or more local agents, if Agent utilization of resources on the local machine is too high, errors could occur.
When you run multiple Agents for load testing, you can view the Agents results as they run from the Benchmark Factory Console.
