Hello Alex,

I've attached the answer I usually send out in Asia. If you hear of anymore
tools, please let me know and I'll add them to the list.

My usual advice to ISPs is to start with cflowd (the new CAIDA version) and
NetFlowMet. In fact, CAIDA is looking for a site to try the new version of
cflowd on a LINUX box - hint hint ;-)

The old one and one of the best for TCP/IP flow analysis. NetFlowMet is a
version of the Unix NeTraMet. It's an RTFM meter which takes its data from a
Cisco router using Cisco's NetFlow data. We used NeTraMet by many ISPs using
a simple on an Intel PC with BSD UNIX and a Digital FDDI card. The results
are dumped to a box that did all the flow analysis and posted the results on
an internal Web server.


cflowd is a package for collecting data from Cisco's flow-export. Its
primary motive is collection of data for capacity planning and similar
activities in a network service provider environment. However, it can been
used effectively in other areas, including usage tracking for Web hosting as
well as security-related investigation activities. This tool
was developed by our customers for their own use. It is free and located at:

Other scripts based on cflowd are located at:

The key Cisco documents on NetFlow are constantly updated (because we are
adding new features and functionality all the time). Do a keyword search on
CCO to find all the documentation on NetFlow.

NetFlow tools (flowdata.h, fdrecorder.c, fdplayback.c, fdg.c) that were used
to build cflowd are located on the Cisco's FTP site:
