Claim One:
1. A method of organizing network performance metrics into historical anomaly dependency data, the method including: assembling performance data for a multiplicity of metrics across a multiplicity of resources on a network and automatically setting criteria based on the performance data over time that qualifies a subset of the performance data as anomalous instance data; constructing a map of active network communication paths that carry communications among first and second resources subject to anomalous performance and representing the active network communication paths as edges between nodes representing first and second resources, thereby forming connected node pairs; calculating cascading failure relationships from time-stamped anomaly instance data for the connected node pairs, wherein the cascading failure relationships are based at least in part on whether conditional probabilities of anomalous performance of the second resources given prior anomalous performance of the first resources exceed a predetermined threshold; and automatically representing the anomalous performance of the second resource as a cascading failure resulting from the anomalous performance of the first resource based on the calculated cascading failure relationships.
