Benchmark Factory for Database 8.2 - User Guide

About Agents

The Benchmark Factory Agent is a component used in Benchmark Factory to create virtual users which simulate real-world user activity by placing transactions against the database-under-test. The Benchmark Factory Agent is installed when the Benchmark Factory Console is installed. In addition, you can install additional agents on other remote machines. Each Benchmark Factory agent can spawn multiple virtual-user sessions and Benchmark Factory can control hundreds of Agent machines.

After installing additional agents, use your Benchmark Factory Console to define a connection to each agent machine. When you create a new benchmark test through the Console, you can select which of the defined agents to use to generate the user load.

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, including transaction times and the number of times a transaction executes.

View Agent Information

The Benchmark Factory Console allows you to view information about all currently running agents, provides a way to connect to and manage remote agents, and allows you to specify some global agent settings. In addition, the primary Agent, Agent.exe, includes a GUI which displays transaction and virtual user statistics during test execution.

• Select View | Agent to open the Agents pane where you can view information about agents that are currently running.
• Select Edit | Settings | Agent to view a list of all the configured agents which are available to be used in testing, as well as platform information about each agent machine. Use this page to view the agent global settings, as well.
• Double-click Agent.exe in the bin directory to open the Benchmark Factory Agent. The GUI displays virtual user statistics during test execution. Select Options | Settings to configure options for this agent.

Types of Agent Components

Benchmark Factory provides several types of agent components:

• Agent.exe—(Windows) The primary agent. This agent is installed with the Benchmark Factory client application and can be found in the bin directory. This component includes a GUI.

• BMFAgent.exe—(Windows or Linux) The non-GUI agent. You can use BMFAgent.exe to integrate Benchmark Factory into your continuous integration or continuous testing process. See BMFAgent.exe for more information.

  • (Windows) The Windows version of this agent is installed with the Benchmark Factory client application and can be found in the bin directory.
  • (Linux) The Linux version of this agent can be installed on a remote Linux machine through the Benchmark Factory Console. See Install Remote Agent on Linux for more information.
