摘要
A new approach that is useful in identifying and eliminating performance degradation occurring in aging software is proposed. A customer-affecting metric is used to initiate the restoration of such a system to full capacity. A case study is described in which, by simulating an industrial software system, we are able to show that by monitoring a customer-affecting metric and frequently comparing its degradation to the performance objective, we can ensure system stability at a very low cost.
