This graph shows server statistics as a function of the elapsed load test scenario time.
In the following example, the CPU usage remained steady throughout the scenario. At the end of the scenario, the number of idle servers increased. The number of busy servers remained steady at 1 throughout the scenario, implying that the Vuser only accessed one Apache server.
The scale factor for the Busy Servers measurement is 1/10 and the scale factor for CPU usage is 10.
