[mrtg] Re: More granular look at traffic transversing WAN link question

[Steve.Gingolaski at tevausa.com]

Greetings -

If you are using Cisco Routers, you might want to start using NetFlow
which is a free feature on all Cisco routers and a few switches.  Netflow
will enable you to see exactly what is going through the links.  You will
need to grab a NetFlow collector.  There are some open source ones - I
have used a few and found them okay - and others are available for
purchase like the one from Crannog Software or NetQOS (do not use Cisco's,
it is not worth the $15k).
If you are not using Cisco routers, then buy some.  No, actually some of
the other manufacturers also support NetFlow (soon to be an IEEE standard)
while still others support a S-Flow which is more or less the same thing.

Hope this helps.

Subject: [mrtg] More granular look at traffic transversing WAN link
question

Can I use MRTG to take a more granular look at the traffic traversing
WAN links?  I'd like to be able to look at a graph and determine what
percentage was AD replication, FTP, etc...  Currently I only have MRTG
graphing WAN Link utilization and was just wondering if I could expand
on that idea.  
Thanks in advance.
David
