Spectral Decomposition and Reconstruction of Telemetry Signals from Enterprise Computing Systems

The System Dynamics Characterization and Controls Laboratory of Sun Microsystems has developed novel continuous system telemetry technology for proactive fault monitoring and “electronic prognostics” capabilities for all types of executing computing platforms. Central to the goal of designing and evaluating prognostic and control systems for enterprise computing platforms is first the ability to simulate telemetric signals and computer system degradation events with real-time models in an interactive computer environment. This paper describes the development and implementation of a Telemetric Parameter Simulation System (TPSS) that employs Fourier-based decomposition and reconstruction methodology with the capability to efficiently decompose any signals into their deterministic and stochastic components, then reconstruct new, simulated signals that possess exactly the same statistical noise idiosyncrasies as the original telemetry variables. The TPSS has become an indispensable tool in Sun’s ongoing development of innovative diagnostic techniques for telemetry operability surveillance and other electronic prognostic applications in enterprise in Sun’s present and future computer platforms.
