Abstract: In response to the problems of low processing performance, poor scalability, and high coupling with business in existing monitoring systems for railway electronic payments, this paper conducted in-depth research on the monitoring and operation maintenance of information systems, and designed and developed a new generation of railway electronic payment application monitoring system based on business platforms, with log data as the core, and applying technologies such as big data and time series based data processing, algorithm based business analysis, etc. This system can implement pre monitoring and early warning, in-process operation and maintenance disposal, and post traceability analysis of electronic payment abnormal events, has core functions such as transaction monitoring, system environment monitoring, business monitoring, alarm configuration, operation and maintenance management, operation and maintenance disposal, and business analysis, provides strong support for ensuring the stable operation of railway electronic payment platforms and related business decisions.
