中文摘要：
系统性能的监测与分析是发现系统运行过程中的瓶颈、优化系统性能的有效手段。传统的监测工具缺乏完善的监控系统，数据表达的细度和深度不够，对系统本身性能有较大影响。本文设计并实现一种基于ETW机制的可视化监视系统Perfornitor，该系统可以较好地解决上述问题；利用Perfornitor对两个具体性能监测的实例进行分析，结果表明该技术能够为系统分析员快速发现并解决系统性能问题提供有效的帮助。
英文摘要：
System performance monitoring and analysis is an effective means to discover bottlenecks running in the system and op- timize system performance. Traditional monitoring tools are lack of a satisfactory monitoring system, not detailed and deep enough in data presentation, having a great impact on the performance of the system itself. This paper designs and implements a visual monitoring system based on ETW mechanism, the Perforuitor, which can solve the above problems preferably. The paper analyzes two specific performance monitoring examples using the Perfornitor. The results show that the technology can provide effective helps for system analysts to quickly identify and resolve system performance issues.
