FIELD: information technology.
SUBSTANCE: method is performed in at least one observable device in a group comprising at least two devices, the observed device has at least one first parameter correlated with at least one second parameter of the at least one second device in the group, mentioned parameters represent the state variables of the mentioned devices. The method comprises: predicting the value of the first parameter based on the measured value of the second parameter; comparison of the predicted value of the first parameter and the measured value of the first parameter; and analysis of the result of the comparison carried out at the comparison stage in order to detect a potential failure.
EFFECT: providing preventive failure detection.
