A list of Cisco NetFlow partners is available off the NetFlow web site.
Most of the commercial solutions tend to focus on particular areas such
as traffic analysis or security monitoring and some cover multiple
areas.

Approximately 3-5% of the switched traffic is on average exported to the
collector.  This number does vary based on what or where, you are
monitoring, application and Cisco platform. 

 

You may want to search the flow tools archive because the sizing
question answers are available.  Also we do have sizing information for
Cisco collector.

Hello everyone,

 

We're way behind, i know, but we would like to deploy Netflow analyzers
to 

be able use all the nice features of netflow, track ddos, plan growth, 

accounting,...

 

Our unix admins will install the software, because from what i've seen 

almost all tools are *nix based, which i'm not that familiar with, i
just 

need to give the the information they need to get servers,..

 

>From my readings, i understand that i first need to know how much i
will 

export, as of flows/sec and bytes/sec, and how do i calculate this,
educated 

guess ? 

 

>From all your experiences, tell me, what do i need to writedown,
Flows/sec, 

bandwidth, placing servers at PoPs or data center, the technical specs
of 

these servers, memory, hardrives, processors, how many machines, 

 

which flow applications, they are too many to try, whats the most
commonly 

used and successfully deployed?

 

I looked at stager, it has nice graphs, same for flow-tools +rrdtools,..

 

Can any one help me to compile a list of questions i need to answer to 

determine the information i will give to our sysadmin to start ordering
the 

servers..
