<p>A fault which is possible to occur for detected correlation destruction is estimated. A fault detection apparatus 10 includes a storage unit 12 and a correlation model comparison unit 25. The storage unit 12 stores correlation destruction set information 33 which indicates correlations on which correlation destruction was detected when a fault occurred, among correlations included in a correlation model representing correlations between a plurality types of performance values of a system. The correlation model comparison unit 25 calculates a commonality between the correlation included in the correlation destruction set information and correlation on which correlation destruction is detected for inputted performance values.</p> |
