SYSTEM AND METHOD FOR COMPUTING OF ANOMALIES BASED ON FREQUENCY DRIVEN TRANSFORMATION AND COMPUTING OF NEW FEATURES BASED ON POINT ANOMALY DENSITY

摘要

Method for computing of anomalies based on frequency driven transformation of a at least one measured signal from a information technology infrastructure element, wherein the measured signal is continuously processed as a digitized signal having a discrete number of measurement points, each measurement point having a same predetermined distance on a time axis and the digitized signal is transformed into a Fourier signal in a frequency space, wherein the computing of anomalies comprises repeating the following steps: calculating an energy content of a predetermined number of high frequency components of the Fourier signal, determining whether or not a point anomaly has occurred based on a comparison wherein of the calculated energy content with a learned threshold, and storing a first predetermined number of calculated energy content.
