Abstract

The present invention relates to a method and system for predicting associated faults, wherein the predicting method for associated faults comprises the following steps: obtaining historical fault information of a distributed computing system, and obtaining a fault information sample database according to the historical fault information; The effective fault information of the distributed computing system is obtained by discretizing the effective fault information in time to obtain the sample data matrix; according to the sample data matrix, the current probability sharing risk group structure of the distributed computing system is obtained; the current data of the distributed computing system collected in real time is obtained Fault sample information: According to the current probability sharing risk group structure and current fault sample information, fault prediction is performed on the distributed computing system. The present invention can fully and accurately describe the diversity and propagation characteristics of associated faults, improve prediction accuracy, effectively improve the execution efficiency of prediction methods, facilitate the deployment and implementation of online faults, and have great significance for improving the availability and reliability of distributed computing systems .

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...
