A monitoring method that is executed by a monitoring device that monitors communication between an information processing device from among a plurality of information processing devices and a switching device that is coupled to a peripheral device that includes at least one of an input device and an output device, the monitoring method includes storing information on a recovery method for each process of the communication, in a memory; detecting the communication between the information processing device and the switching device; determining whether a failure has occurred in the detected communication by analyzing the detected communication for each of the processes; and executing restoration processing of recovering the detected communication, based on information on the recovery method corresponding to a failed process among the processes, which is stored in the memory when it is determined that the failure has occurred in the detected communication.
