Fault root cause determination method and device and computer storage medium

Abstract

The invention discloses a fault root cause determination method and device and a computer storage medium, and belongs to the technical field of networks. And the management equipment obtains the fault characteristics of the target network with the fault. The fault feature is determined based on the knowledge graph of the target network in which the fault occurs. The knowledge graph comprises a network entity and an abnormal event entity. And the abnormal event entity is connected with the abnormal network entity. The abnormal network entity is the network entity generating the abnormal event in the target network. The abnormal event entity is used for indicating an abnormal event generated by the abnormal network entity. The type of the network entity is network equipment, an interface, a protocol or a service. And the management device determines a fault root cause of the target network according to the fault feature. According to the invention, fault propagation between devices is considered, and the accuracy of determining the fault root cause in the network is improved.

Description

technical field [0001] The present application relates to the field of network technologies, and in particular, to a method and device for determining a root cause of a fault, and a computer storage medium. Background technique [0002] Due to the complicated causes of faults in the current network, for example, in the data center network (DCN), the address resolution protocol (ARP) table entry exceeds the limit, the device restarts or the router identity conflict, etc. It will lead to network failure, so network troubleshooting is more difficult. [0003] At present, a method is proposed to determine the root cause of the fault in the network (hereinafter referred to as the root cause of the fault) through the fault tree. In the rule-based fault tree, a root cause determination rule can correspond to a fault root cause. When the performance of the network data obtained in the fault scenario conforms to a root cause determination rule, the fault that caused the fault scenar...
