PROBLEM TO BE SOLVED: To efficiently detect an abnormal information processing apparatus in an information processing system having a plurality of information processing apparatuses. SOLUTION: A detection apparatus stores the average processing time of each previously estimated service out of a plurality of services provided by respective information processing apparatuses. On the basis of communication packets acquired in a prescribed period, the number of calls calling each service in each information processing apparatus is calculated and busy time which is total time of transaction execution is calculated. When a coordinate value indicated by the calculated number of calls and the calculated busy time is separated from a hyperplane indicated by the average processing time of each previously estimated service over a prescribed reference in a multi-dimensional space composed of a coordinate axis indicating the number of calls of each service and a coordinate axis indicating the busy time, occurrence of abnormality in the information processing apparatus is decided.
