Detecting a failure condition in a system using three-dimensional telemetric impulsional response surfaces

A computer-readable storage medium storing instructions that when executed by a computer cause the computer to perform a method for facilitating high-sensitivity detection of an anomaly in telemetry data from an electronic system using a telemetric impulsional response fingerprint of the telemetry data, the method comprising:

• applying a sudden impulse step change to one or more operational parameters of the electronic system during operation;
• generating a three-dimensional (3D) telemetric impulsional response fingerprint (TIRF) surface from a dynamic response in the telemetry data associated with the one or more operational parameters to the sudden impulse step change;
• and
• determining from the 3D TIRF surface whether the telemetry data contains an anomaly, which involves:
• generating a reference 3D TIRF surface for the 3D TIRF surface;
• computing a residual response surface between the 3D TIRF surface and the reference TIRF surface;
• and
• determining from the residual response surface whether the telemetry data contains an anomaly.
