Abstract: Embodiments for monitoring a network are provided. In one embodiment, a method is provided. The method includes collecting data containing information on usage of a network by subscribers. The method further aggregates the data for a first type of usage-based function. Further, the method, simultaneously with the aggregating of the data, samples the data for a second, different type of usage-based function. In other embodiments, systems and machine readable media for monitoring usage of a network are also provided that provide simultaneous generation of data sets for first and second usage-based functions.
