With the complexity and diversity of internet business development

the network management monitoring and the probe-type monitoring can not complete the analysis of network quality. It also fail to reflect the experience of user. To solve the above problems

this paper proposes the research on network performance monitoring and the location of problem base on the data of internet. This scheme use SDK to obtain the information of user and the information of data link in the 139 mail app. Finally

Pearson correlation algorithm and matrix solution algorithm are used to locate IP with degraded performance. The output award directs the operation and maintenance specialist for quick and accurate processing.
