Transient detection for predictive health management of data processing systems

摘要

Systems, methods, and other embodiments associated with transient detection for predictive health management are described. In one embodiment, a method includes receiving a health signal from a data outlet. The health signal corresponds to a derivative variable derived from a combination of data processing system metrics not exposed beyond the data outlet. A transient is detected in the health signal. In response to detecting the transient, the method includes performing a corrective action. The example method may also include detecting the transient in a health signal from a data processing system by collecting historical values of the health signal; selecting a first statistical model that best fits the historical values; receiving a present value of the health signal; and applying the first statistical model to the present value of the health signal to determine whether the present value of the health signal is a transient.

主权项

1. A non-transitory computer-readable medium storing computer-executable instructions that when executed by a computer cause the computer to perform a method, the method comprising:
with a component external to a data processing system, receiving a derivative value from a data outlet that isolates data processing system metrics from detection by the component, wherein the derivative value comprises a combination of the data processing system metrics that are not exposed beyond the data outlet; collecting historical values for the derivative value during operation of the data processing system; selecting a statistical model that best fits the historical values from between at least two statistical models; accumulating a cumulative threshold measure by:
calculating an update term based on a difference between a mean derivative value of the selected statistical model and a present value of the derivative value; andadding the update term to a present value of the cumulative threshold measure; when the cumulative threshold measure exceeds an upper threshold, detecting a transient; and in response to detecting the transient, performing a corrective action.
