      •  lr_start_transaction
      •  lr_end_transaction
    • 2.emulate multiple users: parameterize 
      • seatPref: Aisle, Window, or None
      • Update value on: Each iteration
    • 3.verify Web page content

      • lr_output_message
    • 5.replay succeed?
      • Internet Protocol > Preferences > Enable image and text check
• Controller
  • 5: Creating a Load Testing Scenario
    • 1.start the Controller

      • Goal-Oriented Scenario
      • 子主题
    • 2.Controller at a Glance
      • Scenario Groups pane
      • Service Level Agreement pane
      • Scenario Schedule pane
    • 3.generate a load
      • Load Generators button
      • select localhost and click Connect
    • 4.emulate real load behavior
      • Scenario Schedule
        • Schedule by: Scenario
        • Run Mode: Real-world schedule
      • Initialize all Vusers simultaneously
      • a gradual start for the Vusers
        • In the Start X Vusers box, enter 8, and select the second option— 2 Vusers every 00:00:30 (30 seconds).
      • Schedule a gradual closure
        • Stop Vusers, 2 Vusers every 00:00:30
      • emulate different types of users
        • Runtime Settings
          • 1.Run Logic: Number of iterations to 2
          • 2.Pacing: Start new iteration at Random intervals, every 60.000 to 90.000 second(s)
          • 3.Log: Always send messages, Extended log, and select Data returned by server
          • 4.Think Time: Replay think time, Use random percentage of recorded think time. a minimum of 50% and a maximum of 150%
          • 5.Speed Simulation:
          • 6.Browser Emulation:
          • 7.Content Check:
      • monitor the system under load
        • Windows Resources monitor
          • determine CPU, disk, and memory resources.
          • Add Measurements
          • Monitored Server Machines
  • 6: Running the Load Test
    • 1. run a load test scenario
      • Run
      • Start Scenario
    • 2. monitor the application under load
      • 1. Running Vusers - Whole Scenario graph (a)
        • 显示在给定时间运行的Vuser数量。
      • 2. Transaction Response Time - Whole Scenario graph (b)
        • 显示完成每笔交易所需的时间。
      • 3. Hits per Second - Whole Scenario graph (c)
        • 显示方案运行的每一秒内Vuser对Web服务器的点击次数（HTTP请求）。
      • 4. Windows Resources graph (d)
        • 显示方案期间测量的Windows资源。
      • 5. Throughput
        • 显示Vuser在任何给定的秒内从服务器接收的数据量
    • 3. watch a Vuser running in real time
    • 4. view a summary of Vuser actions
      • Show Vuser Log
