Device management apparatus

A device management apparatus including a processor and a non-transitory computer readable medium storing one or more programs executable by the processor to configure the device management apparatus to perform a method comprising:

• (a1) registering, in a storage device of the device management apparatus and for each managed device amongst one or more managed devices managed by the device management apparatus, a managed-device identification information record associating one or more managed device identification information pieces with the managed device;
• (a2) registering, in the storage device and for each other management apparatus, amongst one or more other management apparatuses, managing at least one device which is not managed by the device management apparatus, a management apparatus identification information record associating one or more apparatus identification information pieces with said other device management apparatus;
• (a) acquiring, by the device management apparatus from an external apparatus, a status-change information record for a status change that occurred in a status-changed device, the status-change information record including a device identification information piece identifying the status-changed device in which the status change occurred, address information indicating an address of the status-changed device, and response action information indicating a response action to be caused to be performed on the status-changed device, wherein the response action comprises a name of a servlet which when executed by the status-changed device causes the status-changed device to perform a predetermined action;
• (b) determining, by the device management apparatus, whether or not the acquired status change information record for the status-changed device is a status-change information record for a first managed device amongst the managed devices managed by the device management apparatus, based on whether the device identification information piece contained in the acquired status-change information record corresponds to a managed-device identification information piece registered for the first managed device;
• (c) transmitting an instruction by the device management apparatus to the first managed device, if the device identification information piece contained in the acquired status-change information record for the status-changed device acquired by the device management apparatus is determined in (b) as corresponding to the managed-device identification information piece registered for the first managed device, to instruct the first managed device to perform a first response action associated with the response action information in the status-change information record;
• and
• (d) transmitting, by the device management apparatus, first unprocessed-device information generated by the device management apparatus based on the acquired status-change information record for the status-changed device, to another management apparatus, amongst said one or more other management apparatuses, indicated ⋅ by an apparatus identification information piece registered in association with said another management apparatus and managing a second device which is not a managed device amongst the managed devices managed by the device management apparatus, if it is determined in (b) that the device identification information piece contained in the acquired status-change information record for the status-changed device does not correspond to any of the managed-device identification information pieces registered for the managed devices managed by the device management apparatus.
