Abstract: Accuracy of risks defined for abnormalities that might occur in a system is improved. The risk determination device 100 includes a classification unit 114 and a determination unit 115. The classification unit 114 classifies abnormal patterns 133, each representing a relationship among metrics at a time of abnormality detection in a system, into groups 134 based on a similarity between the abnormal patterns. The determination unit 115 determines, based on the number of abnormal patterns 133 classified into each of the groups 134, likelihood of an abnormality of the corresponding group 134.

Abstract: Even when there is a large time lag between metrics of a target system, a decrease in analysis accuracy of the target system is prevented. An analysis apparatus (100) includes a processing unit (140) and pre-processing unit (130). The processing unit (140) performs comparative analysis of values of a first metric and a second metric in a system to be analyzed. The pre-processing unit (130) identifies, with respect to the comparative analysis of the first metric and the second metric, a temporal correspondence relation between respective pieces of data used as the first metric and the second metric.
