摘　　要：为了提高长时间运行并持续提供服务计算的服务器的可靠性,需要对服务器操作系统性能衰退情况进行检测分析,本文结合时间和度量的衰退检测研究思路,针对具有季节性特征的服务器系统,提出一种系统性能衰退检测的方法。该方法基于层次分析(AHP)算法对多个性能参数进行综合计算,得到系统各个运行周期的衰退检测指标,并对其时间序列进行回归分析;分析结果反应出当前系统性能衰退状况,以及预测服务器未来可能宕机的时间。最后介绍该方法在BRT(Bus Rapid Transit)中的应用。To improve the reliability of the servers which supply long-running and persistent computing and service,it is necessary to detect and analysis the performance degradation of the operation system which run in the server.In this paper,a system performance degradation detection method for the seasonal characteristic system of servers is proposed,which integrates the time-based method of degradation detection with metric-based one.The performance degradation indexes of each system running cycle are calculated by the new method base on AHP（Analytical Hierarchy Process）.Then the method uses regression to analysis the time series of the indexes.The results will reflect the state of current system performance degradation and give the approximate downtime of the server in the future.Finally,a case will be introduced in the application of BRT（Bus Rapid Transit）.
