The machines each produce event information (e 1 ...e m ), and event history entries are generated into at least one event history collection on the basis of the event information produced by the machines. The at least one event history collection (13) is analysed to find behavioural events of the machines, and computational distances between the machines are determined on the basis of the basis of the found behavioural events.
