Claim One:
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.
