[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.
Key words： sniffer; promiscuous mode; packet filter; hook function; evaluation system
