Abstract: Debugging the performance problem of distributed system is difficult.Many previous researches，which analyze the distributed system with application specific information，need modifications to instrument the target system.This paper provides a new method to analyze distributed system with a transparent mechanism by utilizing dynamic instrumentation.The experiments prove that the method is both unified and effective in debugging the performance problem of distributed system.

摘要： 分布式系统的性能问题分析是一个公认的难题。以往的很多研究应用相关的数据和方法分析应用性能，这些方法通常需要对应用代码进行修改从而获取必要的执行信息。论文提供了一种针对分布式系统性能问题的新的分析方法，该方法通过动态探针获取通信信息，通过分析分布式系统的通信模式对性能问题进行诊断。实验证明该方法具有通用性和高效性。
