Abstract: The past independent and decentralized monitoring and management mode for software and hardware is difficult to adapt to the reliability requirements of real-time data processing. Based on the microservice architecture, an integrated performance monitoring system was designed and implemented relying on the private cloud platform. Through the SaaS (software as a service) cloud service Web interface provided by the cloud platform, the various types of equipment and services in the center could be transparently classified and managed, which realized the functions of collecting monitoring data and setting abnormal alarm. Experiments show that the integrated performance monitoring SaaS cloud service based on microservice architecture has less performance loss and resource occupation of the monitored device or service, fast data acquisition and push speed, accurate triggering of abnormal events, and closed-loop processing, which can well adapt the performance monitoring requirements of the real-time TT&C (Tracking, Telemetry and Control) data processing center.
