摘要
The present description refers to a computer implemented method, computer program product, and computer system for identifying a service metric associated with a service, identifying one or more abnormalities of one or more infrastructure metrics that occur within a time window around an abnormality of the service metric, determining a set of candidate infrastructure metrics for the service metric based on how many times an abnormality of an infrastructure metric occurred within a time window around an abnormality of the service metric, determining a degree of lag correlation for each candidate infrastructure metric with respect to the service metric, selecting one or more candidate infrastructure metrics having a degree of lag correlation that exceeds a threshold to be a leading indicator infrastructure metric for the service metric, and providing a performance degradation warning for the service when an abnormality of one of the leading indicator infrastructure metrics is detected.
