一种基于代码异常机制的故障特征提取方法

A Fault Mode Extraction Method Based on Fault Exception Mechanism of Code

针对开源云平台系统,该文通过分析系统中的异常处理机制以及日志系统,提出了基于异常信息描述的故障模式提取方法;并过理论分析系统日志能够记录的异常信息特征;系统异常处理机制抛出的异常特征;并结合实验获取日志中能够记录所抛出异常信息的比例,以及提取的异常特征与故障模式的对应关系,从而提出一种基于日志中的异常描述信息,从而进行系统故障诊断。

Respect to open source cloud platform, we proposed a system based on the exception handling mechanism and systemlogging mechanism in which the exception information are recorded. After analyses the features of abnormal information which canbe recorded by the system log, the features of anomaly which thrown by system anomaly's processing mechanism theoretically, weconduct experiments to show the proportion of thrown abnormal information which can be recorded by log, and the correspondingrelations between fault mode and fault pattern. Finally we proposed a method to extract information from the log exception descrip-tion and diagnosis system fault.
