Embodiment Construction

[0015] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0016] First, the system failure scenario is described by taking the process involved in a part of the transfer business commonly used in the system as an example. Such as figure 1 As shown in FIG. 1 , a transfer business is taken as an example in the figure to show a schematic diagram of a traditional network service process. In the figure, when a transfer occurs, the system first calls the transfer interface 110 to activate the transfer process. The transfer interface 110 then internally calls the security interface 120 and the balance check interface 130 . The security interface 120 is mainly used to check the security of the transfer environment to check whether there is any security risk, and the balance check interface checks the balance of the ...

Abstract

The invention relates to a system fault positioning technology based on a Bayesian network, and the technology comprises the steps: carrying out training of a Bayesian network model based on a historical fault data set, so as to generate a Bayesian network inference machine, and summarizing the law that a system interface is liable to cause a fault through the Bayesian network inference machine ina conditional probability table form; executing observation of system change, and triggering the Bayesian network inference machine to predict after determining the observed node with the fault; foreach change source which may cause a fault at the observed node, enabling the Bayesian network inference machine to calculate a posterior probability from which the observed node is caused to have afault according to the conditional probability table; and selecting the calculation result with the maximum posterior probability as a fault positioning result and outputting the result.

Description

technical field [0001] The present disclosure relates to Bayesian network technology, in particular to a system fault location scheme based on Bayesian network. Background technique [0002] With the rapid development of Internet technology, more and more business systems are integrated through the Internet. System integration refers to the integration of separate devices (such as personal computers), functions and information into an interrelated, unified and coordinated system through a structured integrated wiring system and computer network technology, so that resources can be fully shared , to achieve centralized, efficient and convenient management. With the increasing number of integrated system platforms that play a supporting role in the bottom layer (for example, for many Internet giants, the bottom layer contains hundreds or even more platforms or nodes), these platforms will be in a period of time (such as Weekly) the number of changes involving code, databases...
