IaaS (Infrastructure as a Service) cloud platform network fault positioning method and system based on log analysis

Abstract

The invention discloses an IaaS (Infrastructure as a Service) cloud platform network fault positioning method and system based on log analysis. The IaaS cloud platform network fault positioning system comprises a fault injection module, a log acquisition and analysis module, a knowledge generation module and a fault detection and positioning module. Firstly, by injecting various typical network faults, various corresponding fault logs are formed; then aiming at various faults, log information related to network faults of each layer of physical resources, an operation system, a virtual machine, an OpenStack and the like is respectively acquired, and fault feature mining is carried out on the acquired network fault log information by using an Apriori algorithm; on such basis, according to a maximal frequent item set and parameters, such as a supporting degree, a confidence degree and the like, association rules and knowledge, which correspond to the specific network faults, are generated by utilizing a bayes formula; and finally, when a system has a network fault again, the network fault can be compared with the association rules of a knowledge base and analyzed according to an acquired fault log, so that the layer on which the network fault occurs is positioned.

Description

technical field [0001] The invention relates to the fields of cloud computing, computer network and data mining, in particular to network fault detection technology, in particular to a log analysis-based cloud platform network fault location method. Background technique [0002] In today's cloud era with the rapid development of the Internet and big data applications, various new network applications combined with cloud computing continue to emerge, and cloud computing has gradually evolved into the mainstream computing generics of new information systems. Cloud computing is the product of the integration of a series of network technologies and computing technologies such as parallel computing, distributed computing, utility computing, and virtualization. Cloud computing platforms can usually be divided into IaaS, PaaS, and SaaS according to different service levels: IaaS (Infrastructure as a Service) provides virtualization services, that is, virtual machines and correspond...

AI Technical Summary

Problems solved by technology

By analyzing the appearance of fault logs, it is difficult to intuitively locate the root cause of network faults, and every time a network fault occurs, it is necessary to check the logs of each level and each component, which consumes a lot of manpower and material resources, and the results obtained may not be good.
