The disclosed embodiments provide a system that facilitates the processing of network data. During operation, the system causes for display a graphical user interface (GUI) for configuring the generation of time-series event data from network packets captured by one or more remote capture agents. Next, the system causes for display, in the GUI, a first set of user-interface elements containing a set of statistics associated with one or more event streams that comprise the time-series event data. The system then causes for display, in the GUI, one or more graphs comprising one or more values from the set of statistics. Finally, the system causes for display, in the GUI, a value of a statistic from the set of statistics based on a position of a cursor over the one or more graphs.
