Fault preventing and intelligent repairing method and device for network management system

The invention relates to a fault preventing and intelligent repairing method and device for a network management system. The device comprises a fault detection module, a fault prevention module and a fault repairing module; and the method comprises the following steps of: setting corresponding early warning thresholds, fault thresholds, early warning repairing policies and fault repairing policies for system parameters related to faults in the network management system in advance; after monitoring, if the system parameters related to faults are more than or equal to the corresponding early warning thresholds and less than the corresponding fault thresholds, generating early warning messages, finding the corresponding early warning repairing policies and repairing the early warning; through monitoring, if the system parameters related to the faults are more than or equal to the corresponding fault thresholds, generating fault messages and reporting fault warning; and according to the fault messages, finding the corresponding fault repairing policies and repairing the faults. By adopting the fault preventing and intelligent repairing method and device which are disclosed by the invention, fault occurrence probability of the network management system is reduced to the greatest extent, and fault repairing speed is improved.
