Prediction of service level compliance in it infrastructures

摘要

A method is provided of predicting a degree of service-quality compliance in an IT infrastructure. The method is carried out at a current point of time within an evaluation period before the end of the evaluation period, wherein service-quality compliance means that a service-quality parameter of the IT infrastructure complies with a service-quality objective. The method includes obtaining a statistic which indicates probabilities that the service-quality parameter will comply with the service-quality objective in sub-periods of the future part of the evaluation period. The statistic is based on known compliance frequencies in equivalent sub-periods in the past. A calculation, on the basis of the statistic, indicates an estimated duration in which the service-quality objective will be complied with during the future part of the evaluation period.
