Micro-service fault root cause positioning method and device based on causal inference

Abstract

The invention provides a micro-service fault root cause positioning method and device based on causal inference, and solves the problems that a current micro-service fault root cause positioning method cannot give consideration to positioning accuracy and positioning efficiency, and the network operation cost is large. The method comprises three stages of fault network element positioning, causal inference model construction and fault root cause positioning, and can strictly distinguish the causal relationship between component nodes, thereby being capable of eliminating redundant nodes, overcoming the defect that traditional manual or simple machine operation and maintenance are time-consuming and labor-consuming, and meanwhile, the fault root cause can be quickly and accurately positioned through the causal traceability characteristic, and the method has certain research value and significance for development of intelligent operation and maintenance.

Description

technical field [0001] The present invention relates to the technical field of data analysis and causal inference, and more specifically, to a method and device for locating the root cause of a microservice fault based on causal inference. Background technique [0002] In recent years, the application scenarios of the microservice framework have become more and more extensive. In the microservice architecture, an application can be decoupled into multiple microservices. When a fault occurs, the fault will propagate throughout the dynamic topology network, causing alarms on multiple nodes and an alarm storm, which will double the difficulty of operation and maintenance. Therefore, once a microservice fails and the root cause cannot be quickly located and resolved, it will directly affect the user experience and bring huge economic losses to the application enterprise. [0003] At present, many fault root cause location methods have been proposed, such as methods based on eve...
