Claim One:
1. A method of determining an anomalous state within a processing system, said method comprising: obtaining, by a processor, one or more values of one or more metrics of the processing system; determining, by the processor, one or more sets of predicted values for one or more points in time in the future for one or more metrics, wherein a set of predicted values for a point in time in the future comprises one or more predicted values for the point in time in the future, and wherein the determining is based on one or more values of one or more metrics; determining, for one or more sets of predicted values, one or more change values, wherein a change value for a set of predicted values represents one or more changes in the set of predicted values; computing for one or more selected times of the one or more points in time in the future one or more seasonal residuals, wherein the computing a seasonal residual for a selected time comprises computing a difference between a predicted value at the selected time and a real value at that selected time in a previous season to obtain the seasonal residual for that selected time; and determining, by the processor, at a current time, based on the one or more change values, whether an anomalous state exists within the processing system at a future time, wherein the determining whether the anomalous state exists uses the one or more seasonal residuals, wherein the determining whether the anomalous state exists comprises combining at least one seasonal residual of the one or more seasonal residuals with at least one change value of the one or more change values to obtain one or more anomaly scores to be used to determine whether the anomalous state exists, and wherein the combining comprises averaging the at least one seasonal residual with the at least one change value.
