An application of an automation operation and maintenance tool design and application.

This article designs an automated operation and maintenance tool for applications to achieve real-time awareness, fault diagnosis and self-healing of the application's operational status. The tool collects information about the application itself and its operating environment in real time to enable timely diagnosis and early warning of application faults, and visualises the results. At the same time, the tool precipitates the collected historical operation information and fault records to improve the fault diagnosis algorithm, and finally achieve accurate diagnosis and self-healing of application faults. The results of the application show that the tool effectively enables timely diagnosis and self-healing of application faults, shortening the detection and disposal time of system faults.
