Abstract:
1. A method for monitoring electromagnetic interference (EMI) signals to facilitate proactive fault monitoring in a computer system, comprising: receiving at an analysis mechanism EMI signals from one or more antennas located in close proximity to the computer system; using a Fast Fourier Transform (FFT) to convert the received signals to the frequency domain; converting the output of the FFT into time series frequency signals for different frequencies; determining correlations between the time series frequency signals and other system telemetry signals to identify time series frequency signals which are highly correlated with the other telemetry signals; constructing a model during a training phase by determining correlations between a set of signals, wherein the set of signals includes the identified time series frequency signals and the other telemetry signals; and comparing the time series frequency signals with corresponding estimated time series signals produced by the model to detect anomalies during a monitoring phase.
