Abstract
In determining a condition of a case under which the occurrence rate of the performance abnormality is high based on information related to a resource utilization situation acquired in a resource utilization situation acquisition step and an occurrence frequency of a request acquired in a request occurrence frequency acquisition step, and information related to the existence/nonexistence of the performance abnormality determined in a performance abnormality existence/nonexistence determination step, when branching a parent node that represents a situation of a decision tree to two child nodes using the method of decision tree, the decision tree is generated using an evaluation function which performs branching such that most of normal samples which belong to the parent node are contained in the one child node, and most of abnormal values which belong to the parent node are contained in the other child node.
