If you are using sampling @ the netflow device, remember
that ntop won't know about it - so if ntop see 1/10th of the traffic, it only
reports on 1/10th.

Are you using span ports or netflow?

Subject: [Ntop] Sampling Rate - netflow
Hi
there...
I just
started using Ntop recently and am having a hard time understanding the numbers
that it is reporting.
We
have three cisco routers sending netflow data to our ntop box. Two 6509's
and one 2821. They are the three core routers in our network (2 6509's for
BGP upstream - 2821 for peering/downstream)
The
Ntop is only reporting peaks of 30-40Mb/s network load etc. and the amount
of http traffic it's reporting is very low.... I presume this is something to do
with the sampling rate in ntop OR could it be a config option on the 6509
side??
Just
looking for a little guideance... thanks...;)
