Abstract: According to an embodiment, provided is an information processing device that is capable of communicating with an apparatus through a first communication path and is capable of communicating with an apparatus management device for managing the apparatus through a second communication path. The information processing device includes: a searching unit that searches apparatuses capable of communicating with the information processing device; a registration requesting unit that requests the apparatus capable of communicating with the information processing device through the first communication path among the searched apparatuses to register thereto management information for the apparatus; and a notifying unit that notifies the apparatus management device of the management information based on notification indicating a fact that the management information has been registered from the apparatus.

Abstract: An equipment managing apparatus manage equipments via a data channel. Management information for grouping an equipment to be managed according to a condition is retained, and request process content information indicating contents of a request process and equipment information is acquired from event information. The equipment managing apparatus updates the management information based on the request process content information and the equipment information, in order to register or delete data of the management information.
