Log collection and analysis based operation scheme is very important in the design of modern software systems, which helps system administrators to enhance data security and service stability. Firstly, this paper discusses the existing operation approaches based on log collection and analysis. Secondly, with the open source ELK framework, this paper gives a detailed design of the operation subsystem in graduate student information platform. The proposed design can effectively fulfill the practical requirements of the graduate school, like performance and workload monitoring, user behavior tracking and error tracing, by using the real-time interactive data analysis on system and application logs. Finally, this paper demonstrates the interactive dashboard implementation of our operation subsystem under different business scenarios.
