Diagnostics information extraction from the database signals with measureless parameters

摘要

In general the invention relates to a method for processing signals from a data server. The method includes obtaining, by a monitoring facility, a measured signal from the data server, wherein the monitoring facility comprises a central processing unit, generating a first probing characteristic from the measured signal, and determining that the first probing characteristic is measureless. The method further includes decomposing, by the central processing unit in response to the determination, the first probing characteristic into a plurality of component parts, constructing a reconstructed signal using a first one of the plurality of component parts, generating a second probing characteristic using the reconstructed signal, wherein the second probing characteristic is not measureless, and processing the reconstructed signal by the monitoring facility.

1. A method for performing diagnostics on a data server element located on a data server comprising:
deploying, by a monitoring facility, a probe on the data server to measure a performance metric of the data server element, wherein the data server element is at least one selected from a group consisting of a central processing unit (CPU), a memory, a storage unit, a network stack, and an operating system kernel; obtaining, by the monitoring facility, a measured signal from the probe on the data server based on the performance metric of the data server element, wherein the monitoring facility is external to the data server; generating a first probing characteristic from the measured signal, wherein the first probing characteristic is a data-generating model; determining that the first probing characteristic has at least one infinite moment; decomposing, by the monitoring facility and in response to the determination, the first probing characteristic into a plurality of component parts; constructing a reconstructed signal using a first one of the plurality of component parts; generating a second probing characteristic using the reconstructed signal, wherein the second probing characteristic has no infinite moments; determining, by the monitoring facility, that the second probing characteristic indicates a deviation from a normal system behavior of the data server element; and generating, by the monitoring facility, an alert warning a system administrator of the deviation by the data server element.
