Measurement by the Software Design for the Power Consumption of Streaming Media Servers

The power consumption of the streaming media server can be obtained in real time by the virtual instrumentation software module described in this paper without an additional hardware meter. From the observation of experiment's data we conclude that the measurement of the power consumption of the streaming media server depends on the CPU utilization exquisite dynamically and with some system operation parameters. We form a model to represent the power consumption with respect to the CPU utilization. By using the software method based on this model, users can perform the measurement of the power consumption of the PC at any time even remotely through the Internet. Once the required measurements are made, the acquired data can be immediately transferred back to the monitor server in order that the measured data can be analyzed in more detail. To facilitate the measurement process, we also designed a suitable graphic user interface. Our method has been tested through a comparison with the measurement results by means of a power meter
