This invention solves the problem of RSS, i.e., the possibility of notification failure while taking its advantage that allows use of existing software such as a browser. For this purpose, an RSS control unit detects failure occurrence via an internal interface, gives a level corresponding to the type of the failure to the failure information, generates an RSS information unit that describes the failure information, and registers the RSS information unit in a database. A client accesses a WWW server of a multi-function device based on an URL registered in advance at a predetermined timing, and displays the contents of an RSS information unit acquired by searching the newly registered RSS information units. If an event of recovery from failure has occurred, the RSS control unit lowers the level corresponding to the RSS information unit of the recovered failure.
