ABSTRACT:
An operation monitoring apparatus monitors statuses of plural monitoring target apparatus connected to a network, by sending a connection confirmation mail, via a notification server located on the network, receiving the connection confirmation mail and an operation confirmation mail sent from each monitoring target apparatus, storing a scheduled transmission time of a next operation confirmation mail contained in the operation confirmation mail, as part of apparatus information of the monitoring target apparatus and judging, using the scheduled transmission time, whether the next operation confirmation mail has been received. The judgment is not made if a latest connection confirmation mail sent from the operation monitoring apparatus itself has not been received.
