From a stream of digital data units (10), which exhibits gaps as a result of parameter monitoring, the number of missing data units must be determined and the response time of the parameter monitoring must be estimated at the place of determination for non-conforming data units (15, 16, 17; 21). The method is based on using the identification number (12, 13, . . . ), which is carried by the data unit (10), to detect the gaps. A starting time (L12) is established with the arrival of a first conforming data unit, which is continuously updated as long as no gap occurs. After a gap is detected, the updated time (L14) of the last conforming data unit serves as the lower barrier (L[1]) of the response time, that of the first conforming data unit (18) after the gap as the upper barrier (U[1]) of the response time. The number of missing data units can be derived from the gap in the identification numbers. The method can be immediately continued, so that many values can be stored and used for a statistical evaluation.
