Abstract: A user terminal 1, which is communicably connected to a server device 2 via a network 9, includes: an information acquisition unit 101 that acquires terminal information including a terminal ID of the user terminal 1, and acquires peripheral device information including a device type and a serial number of a peripheral device 3 connected to the user terminal 1 via an interface 15 for peripheral device connection, which is different from a network interface 16 connected to the network 9; and a transmission/reception unit 102 that transmits the terminal information and the peripheral device information to the server device 2.

Abstract: An information processing device, to which a peripheral device 3 using a consumable item is connected, includes: an information acquisition section 101 that acquires peripheral device information including a use amount of the consumable item used on the peripheral device 3, acquires a cumulative use amount of the consumable item by accumulating the use amount, and acquires an event log including contents of an event that has occurred on the information processing device and an occurrence date/time of the event; a limit value calculation section 104 that calculates an estimated limit value of the use amount of the consumable item based on the cumulative use amount of the consumable item obtained at the occurrence date/time of the event regarding the event log including the contents regarding the consumable item; and a threshold value calculation section 106 that calculates a threshold value for judging a timing to output a replacement/replenishment prompt notification in comparison with a current cumulative us
