Abstract: Failure prediction is of great significance for improving the stability of the computer system and log analysis is an effective way of establishing the failure prediction model.On the basis of time prediction model for the same kind of failure，this article establishes the associated mode for different kinds of failure by the log analysis and the failure prediction model based on the associated mode，which fills the disfigurement of time prediction model’s powerlessness within a short time after the occurrence of failure and improves the rate of predication greatly.The validity of the failure prediction model based on associated mode is tested by the data of BlueGene/L’s system log of IBM.
