In state detection of a system using a correlation destruction pattern, the versatility of the correlation destruction pattern is improved. A system analysis device (100) includes a correlation destruction pattern storage unit (113), an aggregated destruction pattern generation unit (104), and a similarity calculation unit (105). The correlation destruction pattern storage unit (113) stores a plurality of correlation destruction patterns (123) each of which is a set of correlations in which correlation destruction has been detected among correlations of pairs of metrics in a system. The aggregated destruction pattern generation unit (104) generates an aggregated destruction pattern (124) which is obtained by aggregating correlation destruction patterns (123) of the same type among the plurality of correlation destruction patterns (123). The similarity calculation unit (105) calculates and outputs a similarity between the aggregated destruction pattern (124) and a newly-detected correlation destruction pattern (123). |
