1. A system including one or more processors coupled to memory, the memory loaded with computer instructions to rank anomalies in an anomaly cluster, the instructions, when executed on the processors, implement actions comprising:

  • accessing 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, wherein the anomalous instance data are grouped in a cluster of operation anomalies that are interrelated as cascading failures traced over active network communication paths among resources, wherein the communication paths propagate anomalous performances;

    constructing a map that graphically depicts propagation of the anomalous performances along the active network communication paths as edges between nodes representing the resources; and

    calculating impact rankings for the nodes, based at least on attributes of the resources exhibiting anomalous performances.
