1. A method, comprising:
accessing a first data flow log event in a data flow log;
determining whether the first data flow log event is a request event or a response event by determining whether a first port value is above or below a predetermined threshold or whether a second port value is above or below the predetermined threshold;
generating an identifier for the first data flow log event based on the first data flow log event being the request event or the response event; and
incrementing an event count associated with the identifier.
