Abstract

The invention provides a relevant failure prediction method and system. The relevant failure prediction method comprises the steps of acquiring historical failure information of a distributive computing system and acquiring a failure information sample database according to the historical failure information; acquiring effective failure information in the failure information sample database and performing time discretization processing on the effective failure information to obtain a sample data matrix; acquiring a current probability shared risk group structure of the distributive computing system according to the sample data matrix; acquiring current failure sample information of the distributive computing system that is collected in real time; performing failure prediction on the distributive computing system according to the current probability shared risk group structure and the current failure sample information. The method and the system can describe the diversity and transmissibility characteristics of relevant failures comprehensively and accurately, improve prediction precision, effectively increase the prediction method execution efficiency and facilitate online failure deployment and implementation, and are of great importance for improving the availability and the reliability of the distributive computing system.

Description

technical field [0001] The invention relates to the field of distributed computing systems, in particular to a method and system for predicting associated faults in the distributed computing system. Background technique [0002] A distributed computing system is composed of multiple heterogeneous and interconnected computing elements (CE: Computing Elements), and these systems usually carry a large number of parallel and collaborative applications. However, with the increase in the scale of computing units, the complexity of the interaction between computing units and other system components, and the diversification of applications carried by the system, distributed computing systems are more prone to failures and abnormalities. These failures are temporally and spatially correlated. This associated failure will cause abnormalities in other computing units in the system, and even affect the availability of the entire distributed computing system. Fault prediction can predi...
