Abstract: A computer system and computer-automated method for analyzing performance data in a utility network, such as electricity, gas or water supply, are described. A data set is provided that contains a log of a first time sequence of network events which are classified into event types. A second time sequence is generated from the first time sequence by aggregating the events into event groups, and at least a third time sequence is generated by aggregating the event groups into event super-groups. A multi-level time sequence event hierarchy is thus created. The multiple time-sequence levels are rendered into a visualization in which the different event types are visually distinct from each other. The visualization reveals to a domain expert patterns of behavior in the data set which can be used to detect current network problems and to predict future network supply and consumption, for example in a utility network operations center.
