Abstract: The disclosed embodiments provide a system that facilitates the processing of network data. During operation, the system provides a graphical user interface (GUI) for obtaining configuration information for configuring the generation of time-series event data from network packets captured by one or more remote capture agents. Next, the system provides, in the GUI, a first set of user-interface elements for including one or more event attributes in the time-series event data of an event stream associated with a protocol classification of the network packets. The system then includes the one or more event attributes specified through the first set of user-interface elements in the configuration information.
