A fault information collection program capable of accurately determining redundancy of information related to an identical fault even in cases where information indicating the same fault of the same target of monitoring is received from multiple devices. When new fault information including fault detection date and time is input, the latest fault information indicating a fault related to the fault identical with that of the new fault information is acquired from a message information storage means storing a plurality of past fault information including detection dates and times of faults. It is then determined whether or not a predetermined messaging interval has elapsed since the fault detection date and time indicated by the latest fault information until the fault detection date and time indicated by the new fault information. If the messaging interval has elapsed, the new fault information is stored in the message information storage means as valid fault information.
