1. A method for processing signals from a data server comprising: 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; determining that the first probing characteristic is measureless; 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.
