摘　　要：[目的/意义]为解决图书馆数字资源群的数据统计与效益分析问题,设计基于网络旁路监听方式进行数据使用统计和分析的评估系统。[方法/过程]引入旁路监听技术方式探讨图书馆数字资源绩效分析的设计思路,以大连理工大学图书馆数字资源评估系统为例,阐述系统的技术支撑原理、设计思路及功能模块解决方案。[结果/结论]通过具体实践证明,基于旁路监听方式的数字资源评估系统可以对数字资源群组实施准确监控,在不影响原有的网络拓扑和使用习惯的前提之下,准确识别并记录读者对数字资源的访问下载情况,最终根据数据库中的访问日志对数字资源的服务绩效进行有效评估。[ Purpose/significance ] To solve the problems of data statistics and benefit analysis of digital library resources, the paper, designs the evaluation system of date statistics and analysis based on the network sniffer system. [ Method/process ] This paper introduces network sniffer technology to discuss the design method of the performance analysis of library digital resources. Taking the evaluation system of digital resources of Dalian University of Technology＇ s Library as an example, it describes the technical support principles, design thinking and modules solution. [ Result/conclusion ] Confirmed by the definite practice, the system can accurately monitor the implementation of digital resources. Under the premise of not affecting the topology structure and users＇ habits of the original network, this system can accurately identify and record the readers＇ access and downloads to electronic resources, and effectively evaluate the service performance of the digital resources by the access log in the database.
