Lucas, begins by introducing flows. Next, the author discusses flow export and how to configure it in both hardware and software; as well as, how to collect those flow records from many different network devices using the industry-standard flow-tools software package. Then, he shows you how to view the flow records you've gathered. The author continues by demonstrating filtering flows that display only interesting data. Next, he shows you how flow-tools support a wide variety of reports. Then, he covers FlowScan, web-based software that offers traffic graphs to your users. The author continues by covering FlowViewer, another web-based tool that lets you deeply dissect your traffic. Next, he shows you how to use gnuplot to create graphs of truly arbitrary floe data. Finally, the author discusses some flow collection edge cases and how you can use flow records to proactively improve your network.
