Active and passive redundant computer system node fault detection method based on IPMI

The invention discloses an active and passive redundant computer system node fault detection method. The method includes the steps that step1, IPMI standard interfaces of redundant computers to be detected is used, a fault detection module collects state data of the main computer to be detected and the standby computer to be detected in a redundant system in real time; step2, after a certain amount of operating state data are collected, the fault detection module diagnoses whether operating faults appear on the computers to be detected or not through a mode matching method; step3, the probability that a fault event appears on the main computer within a period of time is predicted according to given system parameter values. Serving as one of indispensable basic components for achieving redundant system fault tolerance of multiple computers, the active and passive fault detection method can reduce time delay of fault detection, improve accuracy of fault detection and predict occurrence probability of the faults
