Abstract
A monitoring system of the present invention achieves highly reliable switching control by having a monitored response time creating/calculating unit calculate a maximum value and a minimum value between which a response time is judged as normal from a response time of the last measurement and from a response time of the last but one measurement, and by having a monitored response time comparing unit set a range in which a response time is judged as normal in a manner that agrees with past response times.
