PROBLEM TO BE SOLVED: To always properly report an alert in monitoring a device to monitor metrics for business service metrics and system performance, by eliminating the difference between the result of determining an alert for the business service metrics and that for the system performance. SOLUTION: A physical influence relationship between the business service metrics and system performance items is set in a metric map storage part 304 as a metric map. Based on the result of determining an alert for the business service metrics that is determined to be normal by an alert determining means 102, and on a system performance value of a system performance item associated with the business service metrics in the metric map, a threshold value deriving means 105 mechanically calculates, through regression analysis, a system performance value when the result of determining the alert for the business service metrics is normal; the result calculated is stored in a threshold value storage part 303.
