1. A computer-implemented method, comprising: accessing a set of events, wherein each event in the set of events characterizes a computational action or computational communication; determining a set of metrics, wherein each metric in the set of metrics is determined based on a corresponding event in the set of events; generating a population characterization based on the extracted metrics; receiving an input corresponding to an identification of a criterion to use to identify metrics to include in a subset of the set of metrics; analyzing, for each event in the set of events, the extracted metric with respect to the population characterization; determining, for each event in the set of events, whether the criterion is satisfied based on the analysis; generating a subset of metrics that consists of all metrics for which the criterion is satisfied; and generating a visual object that represents the subset of metrics.
