[c-nsp] Usage Billing w/ Netflow / Implementation Pitfalls

[Joe Loiacono]

Well if you're looking at larger subsets, then FlowTracker might work for 
you. You can delineate your user group via a CIDR block (e.g., 
192.168.100.40/29), group of IPs (up to 10, separated by commas, e.g., 
192.168.100.70, 192.168.100.71, etc.), or a combination of the two (e.g., 
192.168.100.40/29, 192.168.110.49, 192.168.100.50)

RRDtool maximums, minimums, averages, and 95th pct. are provided for each 
of the five time periods (last 24 hours, last week, last 4 weeks, etc.). 
You also have the ability, via the web interface, to dump each of the data 
points into a list.
