A fault monitoring apparatus is connected to computer systems and monitors a fault in the computer systems. The fault monitoring apparatus is provided with a storage section for storing and holding fault recovery information including rules for defining recovery operations when faults occur in the computer systems, and when a fault occurs in the computer systems, retrieves the rules previously set in the fault recovery information and instructs the computer systems so as to perform a recovery operation corresponding to a rule matching to the fault which occurs in the computer systems.
