摘要： One embodiment of the present invention provides a system that estimates residual life of a software system under a software-based failure mechanism. During operation, the system first constructs a prognostic database for the software-based failure mechanism based on a plurality of software systems of the same type as the software system, wherein the prognostic database includes a set of prognostic readings associated with the software-based failure mechanism from the plurality of software systems. Note that a given prognostic reading in the prognostic database comprises: (1) a symptom index, which is a function of one or more variables associated with the software-based failure mechanism; and (2) a residual life, which is the remaining time to a failure under the software-based failure mechanism. Next, the system obtains a symptom index value from the software system which is being monitored. The system then estimates a residual life for the software system under the software-based failure mechanism by comparing the symptom index value with the prognostic readings in the prognostic database.

摘要： A system that monitors telemetry from a host computer system to detect degradation in a remote storage device. During operation, the system monitors performance parameters from a host computer system which accesses the remote storage device, wherein the performance parameters relate to the interactions between the host computer system and the remote storage device. The system then determines whether the monitored performance parameters have deviated from predicted values for the performance parameters. If so, the system generates a signal indicating that the remote storage device has degraded.

摘要： Some embodiments of the present invention provide a system that accurately synchronizes signals related to the operation of a computer system. During operation, the system receives a first time-domain signal associated with a first system variable and a second time-domain signal associated with a second system variable from the computer system. The system then transforms the first and the second time-domain signals into a first frequency-domain signal and a second frequency-domain signal, respectively. Next, the system computes a cross-power-spectral-density (CPSD) between the first and second frequency-domain signals to obtain a phase angle versus frequency graph between the two frequency-domain signals. The system subsequently extracts the slope of the phase angle versus frequency graph, and uses the value of the slope to synchronize the first time-domain signal and the second time-domain signal.
