| 摘 要： | 虽然多数的现有监控工具可以提供关于系统整体性能的宏观信息,但是这样的数据并不能帮助用户理解系统内部的运行状况.为了揭示内部行为,提出了一种基于监控元数据的方法来收集系统执行过程中的内部组件状态和通信.新方法能应用于许多网络通讯协议和应用程序类型,通过信息跟踪机制记录系统内部发生的关键性能事件,并捕获它们之间的时序和因果关系,为系统诊断提供支持.

| Abstract: | Large network systems need monitoring to detect flaws and bottlenecks. Many existing monitoring tools only provide overall statistics about global performance metrics. In order to expose the systems internal behavior, we propose a metadata based approach to record the actual execution paths. We have designed proper data structure and information propagation mechanisms to trace the applications internal critical performance-related events. This approach can apply to many network protocols and applications,and it helps capture the sequential and causal relations across domains. Thus it opens a way to diagnose large and complex network systems. |
