With the deepening of the digitization transformation of higher education, the teachers and students in universities put forward higher requirements for the stability and fluency of informatization application. In this paper, considering several typical applications of smart campus and focusing on pain points and blocking points of teachers' and students' experiences on these applications, we use application performance management (APM) related technical tools to achieve accurate evaluation and rapid improvement of smart campus service quality. We carry out a number of end-to-end network monitoring and do the application performance comparison experiments. The results show that the appropriate combination of APM tools can not only uniformly monitor the application performance of front-end web pages, apps, mid-end networks and back-end servers, but also let us quickly locate, analyze and display the experience jam points of teachers and students from the business logic layer and system code layer. In a word, the APM can be used to improve the precision, visualization and initiative of smart campus services.
