Abstract

An method and corresponding apparatus for detecting a change in an aspect of performance of a data processing system and for adjusting operation of a system so as to counter the detected change. The method generating a value representative of an aspect of performance of a data processing system relative to operation of the system in a first sub-period of each in a plurality of first time periods; in which each first sub-period is located with the same degree of offset within the respective first time period. The generated value may represent a norm or typical value for the aspect of behaviour in the sub-period. The method for detecting a change in the aspect of performance by comparing the value generated with a value indicative of the aspect of performance relative to operation of the system in a second sub-period of a second time period; in which the second sub-period is located with a degree of offset relative to the second time period that is the same as the degree of offset each first sub-period has relative to the respective first time period. The method also for initiating adjustment of operation of the system so as to counter the detected change in the aspect of performance of the system.
