Research on Intelligent Operations and Maintenance System Based on Call Chain

With the cloud transformation of the system and the widespread implementation of the distributed architecture, the number of system nodes and micro-services has increased exponentially, and the monitoring workload has risen sharply; The relationship between monitoring objects is extremely complex, data fragmentation and remote storage, all of which bring new challenges to traditional operation and maintenance. Because the traditional maintenance mode is mainly aimed at the system with chimney structure, there are problems such as slow cross-system and cross-layer fault handling, slow cross-domain problem/fault handling, etc., and it is difficult to continue when dealing with new challenges. So this paper proposes an end-to-end intelligent monitoring system across three layers. Through the transformation of the source system and the addition of protocol conversion and other modules, China Telecom's unique cross-three layer data model (IaaS/PaaS/SaaS) has been defined to greatly shorten the fault detection time of the whole network business system, and the fault processing has been shortened from the hour level to the minute level. At the same time, the system fault time has been greatly shortened, and the operation and maintenance efficiency and customer perception have been improved.
