通过对Web信息的跟踪记录可以实现网上用户行为的分析
同时也为Web Server和Web Cache的性能评测提供了原始数据.本文提出了分布式在线评测解决方案.该方案通过网络监听产生评测的日志
并利用分布处理扩大了系统的吞吐率
提高了系统的可用性.同时
通过在线重构、数据内核过滤等关键技术有效地提高了系统的性能.
Detailed measurement results for Web traffic provide the foundations of analysis in both large-scale user's access patterns and performance evaluation of Web servers and Web caches.This paper proposes a distributed online measurement system
which generates rich logs by packet monitoring for Web analysis in the cluster environment.The system gains high throughput and availability by adopting distributed processing technologies.Some new techniques
such as online reconstruction in memory and kernel packet filter
are also adopted to improve the system performance.
