ABSTRACT:
A system that monitors the health of a computer system is presented. During operation, the system receives a first-difference function for the variance of a time series for a monitored telemetry variable within the computer system. The system then determines whether the first-difference function indicates that the computer system is at the onset of degradation. If so, the system performs a remedial action.
