Im running a Fedora Server that is collecting Netflow from our router. We need to use Netflow to monitor bandwidth usage per user. I have setup NTOP  but although many have raved about it, i find there to be little to no reporting. Can anyone reccomend good Netflow collecting/reporting software for Linux?

My favorite, Flow Loader And Virtual Information Output (F.L.A.V.I.O.) is a free and visually smooth data grapher for NetFlow. It gathers data from your router loads it into a MySQL database and can generate daily, weekly, monthly, and yearly charts that are totally customizable for you and your system.  It shows traffic split by ports, statistics on total utilization, and generates percentile 95 information I belive. It is supported in all POSIX environments. It really is a commercial grade, free product many people overlook.

I would recommend to use NetAMS, that can collect and provide HTML view for daily/weekly/monthly statistics per each user (IP address).

http://netams.com/ 

it's a free software with commercial support. It works fine on any Linux and FreeBSD.

English documentation there is still far from the ideal, but the software itself is quite mature and customizable.

netams is a nightmare to install and setup. I cant believe how there isnt an easy way to monitor traffic through a router and see where its coming from and where its going to. For something that seems to be such a fundamental need of every company i really dont see why its such a pain to get something that works well and is easy to set up

Try another collectors, analyzers

1) Commercial, free version available for 2 interfaces only:
http://manageengine.adventnet.com/products/netflow/download.html?free

2) Set of freeware tools to collect and produce reports:
http://www.splintered.net/sw/flow-tools/docs/flow-tools.html
http://www.caida.org/tools/utilities/flowscan/

3) NetFlow collector: http://www.mindrot.org/projects/flowd/

4) NetFlow collector (obsolete): http://www.caida.org/tools/measurement/cflowd/
How to setup and use cflowd: http://brneurosci.org/linuxsetup34.html



I ever tried only Cisco NetFlow Collector and NetAms, so I know nothing about the listed above tools.
