A device management apparatus is capable of communicating with a plurality of devices connected thereto via a network. The device management apparatus includes a storage unit that stores therein setting items and setting values for the devices; an acquiring unit that acquires, from each of the devices, a file describing a setting item currently set in the device and a current setting value of the setting item; a determination unit that determines whether the acquired file includes a setting item not being stored in the storage unit; and a storage controller that causes the storage unit, if the acquired file includes a setting item not being stored in the storage unit, to store therein the setting item not being stored in the storage unit and a current setting value of the setting item.
