Web服务器的负荷状态检测技术

Internet业务请求的汇聚使Web服务器具有高负荷性，极易导致过负荷，文中对其负荷状态的检测方法进行了深入研究．系统内部资源消耗量与业务处理量有直接关系，通过对Web服务器内部多种资源的并行检测可以准确评价其负荷状态。文中在对Web服务器的负荷特性进行分析的基础上，给出了其负荷状态的检测参数、检测模型及基于多个检测参数数据融合的检测方法．通过对监测到的实际系统数据的分析表明了此方法的有效性．

Technique for Load State Detection in Web Server

The concentration of immense services and mass requests in Internet would bring high traffic load to the Web Server. Getting efficient practical load detection techniques becomes very important for Web server to avoid overload. In this paper, some thoroughly research on the method for load state detection in Web server is introduced. Load state could be accurately estimated by synchronous detecting multi internal resource, since internal resource occupancy factor is interrelated to service traffic processed by system. To introduce the approach mentioned above in detail, load sources and traffic characteristics of Web server are analyzed at first. Then load detection parameters and load detection model are presented. Moreover, a novel strategy to detect system load state based on fusion of multi detection data is presented. By some test data from actual system, the theory and method are proved most feasible.
