This data is often leveraged by network and systems administrators to troubleshoot bandwidth issues, identify network congestion, and observe the flow of data.

A sample NetFlow output can be seen in the following screenshot. What is included with flow data can vary between network device manufacturers as there are several versions in the commercial...
