Abstract: An operations management system includes a correlation model storing unit, an analysis order storing unit, an analysis unit, and an order control unit. The correlation model storing unit stores a correlation model which indicates a correlation among plural types of performance values, for each of plural systems. The analysis order storing unit stores a detection order in the plural systems for carrying out detection of correlation destruction. The analysis unit carries out, in each of plural time periods, detection of whether the correlation destruction of the correlation included in the correlation model of each of the plural systems is caused or not by use of performance values inputted for the each of plural time periods, on the basis of the detection order. The order control unit updates the detection order in the each of plural time periods.

Abstract: In invariant analysis applied to a plurality of the analyzed systems, delay in detecting a fault is decreased. An operations management system 1 includes a correlation model storing unit 212, an analysis order storing unit 412, an analysis unit 300, and an order control unit 400. The correlation model storing unit 212 stores a correlation model 222 which indicates a correlation among plural types of performance values, for each of plural systems. The analysis order storing unit 412 stores a detection order in the plural systems for carrying out detection of correlation destruction. The analysis unit 300 carries out, in each of plural time periods, detection of whether the correlation destruction of the correlation included in the correlation model of each of the plural systems is caused or not by use of performance values inputted for the each of plural time periods, on the basis of the detection order. The order control unit 400 updates the detection order in the each of plural time periods.
