History output apparatus, control method, and program

A history output apparatus comprising:

• an acquisition unit that acquires an abnormal event history representing an abnormal event occurring in a terminal;
• a kind determination unit that determines whether a kind of the abnormal event represented by the acquired abnormal event history is a predetermined kind;
• a terminal determination unit that determines, when a kind of the abnormal event is the predetermined kind, a terminal in which the abnormal event occurs, as an output target terminal;
• and
• an output unit that outputs, when the abnormal event represented by the acquired abnormal event history is an abnormal event occurring in the output target terminal, output information relating to the abnormal event, wherein,
• when a certain terminal is determined as the output target terminal, the output unit further outputs output information relating to an abnormal event occurring in the terminal earlier than the determination.

A control method executed by a computer, comprising:

• an acquisition step of acquiring an abnormal event history representing an abnormal event occurring in a terminal;
• a kind determination step of determining whether a kind of the abnormal event represented by the acquired abnormal event history is a predetermined kind;
• a terminal determination step of determining, when a kind of the abnormal event is the predetermined kind, a terminal in which the abnormal event occurs, and another terminal communicating with the terminal at or before a point when the abnormal event occurs, as output target terminals;
• and
• an output step of outputting, when the abnormal event represented by the acquired abnormal event history is an abnormal event occurring in the output target terminal, output information relating to the abnormal event.

• and
• in the output step, when a certain terminal is determined as the output target terminal, further outputting output information relating to an abnormal event occurring in the terminal earlier than the determination.
