The application discloses a fault root cause location method and device, and a computer storage medium, which belong to the field of network technology. The management device acquires a first knowledge graph of the target network where a fault occurs, and an abnormal network entity that generates an abnormal event in the target network is identified on the first knowledge graph. The management device generates n abnormal sub-graphs based on the first knowledge graph, and each abnormal sub-graph includes one or more abnormal network entities. When the abnormal sub-graph includes multiple abnormal network entities, any abnormality in the abnormal sub-graph Fault propagation conditions are met between the network entity and one or more other abnormal network entities in the abnormal sub-graph, n abnormal sub-graphs include all abnormal network entities on the first knowledge graph, and any abnormal network entity belongs to only one Anomaly submap. The management device determines root cause faulty network entities in the one or more anomalous submaps. The application improves the accuracy of fault root cause location in the network.
Description
technical field [0001] The present application relates to the field of network technology, in particular to a fault root cause location method and device, and a computer storage medium. Background technique [0002] Due to the complex causes of faults in the current network, for example, in the data center network (data center network, DCN), the Address Resolution Protocol (Address Resolution Protocol, ARP) table entry exceeds the limit, the device restarts or the router identity (router identity) conflict, etc. It will lead to network failure, so network troubleshooting is more difficult. [0003] At present, a method of determining the root cause of a fault in a network (hereinafter referred to as: the root cause of the fault) through a fault tree is proposed. 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 a fault scenario conforms to a root cause determination rule, ...
