一种通用的可扩展OpenStack云能耗监测框架
A Generic and Extensible Framework for Monitoring Energy Consumption of OpenStack Clouds
摘要：
虽然云计算已经改变了IT行业，但它是建立在大型数据中心的基础上的，这些数据中心通常消耗大量的电力。我们已经努力减少能源云的消耗，某些数据中心的电力使用效率（PUE）系数现在接近1.08。虽然这是一个令人难以置信的标志，但这也意味着IT基础设施占数据中心消耗的大部分电力。因此，监测和分析能源消耗方式的手段从未如此重要。这种监测不仅是了解电力消耗情况所必需的，也是评估能源管理政策影响所必需的。在本文中，我们从监控大规模系统的经验中吸取教训，并介绍了一个名为KiloWatt API（KWAPI）的能源监控软件框架，该框架能够处理OpenStack云。该框架的架构是可伸缩的，可扩展的，并完全集成到OpenStack中，支持多种瓦特计设备，多种测量格式，并最大限度地减少通信开销。
英文摘要：
Although cloud computing has been transformational to the IT industry, it is built on large data centres that often consume massive amounts of electrical power. Efforts have been made to reduce the energy clouds consume, with certain data centres now approaching a Power Usage Effectiveness (PUE) factor of 1.08. While this is an incredible mark, it also means that the IT infrastructure accounts for a large part of the power consumed by a data centre. Hence, means to monitor and analyse how energy is spent have never been so crucial. Such monitoring is required not only for understanding how power is consumed, but also for assessing the impact of energy management policies. In this article, we draw lessons from experience on monitoring large-scale systems and introduce an energy monitoring software framework called KiloWatt API (KWAPI), able to handle OpenStack clouds. The framework --- whose architecture is scalable, extensible, and completely integrated into OpenStack --- supports several wattmeter devices, multiple measurement formats, and minimises communication overhead.
