1. A method for detecting an anomaly in a processing environment, the method comprising: obtaining, by a processor, a series of values collected within a processing interval of the processor of the processing environment, wherein the values comprise transactional data provided from more than one source in the processing environment; normalizing, by the processor, the series of values to obtain a first series of normalized values; generating a second series of normalized values by applying a predictive filter to the first series of normalized values, wherein each normalized value in the second series of normalized values comprises a predicted value based on a value in the first series of normalized values, predicted at a later time in the processing interval, by utilizing the predictive filter; generating a comparison score by comparing the first series of normalized values to the second series of normalized values; and determining whether the comparison score represents an anomaly relative to at least one other comparison score derived from values collected within the processing interval.
