Description

  The present invention relates to an apparatus, a method, and a program for informing a state change of a monitoring target such as a device.

  So far, proposals have been made regarding a system for notifying an abnormality of a device by lighting a warning lamp (for example, see Patent Document 1). However, in the case of the warning light system described in Patent Document 1, since an abnormality of the device is notified by lighting of the warning light, only the person near the warning light is notified. Therefore, there is a need for a system for notifying a person who is remote from a device of the abnormality of the device.

On the other hand, if the device is a computer connected to a computer network such as an in-house LAN, it cannot be connected to the Internet or the like to which an unspecified number of people can connect from the viewpoint of ensuring security, and is connected to the in-house LAN. It is impossible to notify the terminal of the person who is connected to the Internet of the abnormality of the device.
