Patent ID: 7764959

Claim:
A method for analyzing network data using matched filters, the method comprising: obtaining a data set from a source operating within a network, wherein the data set is associated with an event experienced by the source during operation of the source in the network; computing, by a server, one or more values from the data set, the one or more values corresponding to one or more signature elements of a matched filter wherein the one or more signature elements of the matched filter are configured to define a root cause of the event experienced by the source and wherein each signature element is defined by a range of values; evaluating the one or more values based on the one or more signature elements included in the matched filter to generate a contribution for each of the signature elements to a probability of detection based on how the one or more values compare with the range of values; and computing, by the server, the probability of detection for the matched filter based on the contributions from the one or more signature elements, the probability of detection indicating a likelihood that the root cause of the event has occurred at the source of the data set.
