Johannes,
I am in the same situation as you.... I have multiple gigs of traffic
coming from a Foundry XMR 8000 and NTOP is showing it as a small meager
amount compared to what is being sent out....... Any help from the
list would be greatly appreciated.

Hey guys,
okay so i tested with sflowtools for incorrect packetsize which is not
the case (that's reported correctly).
I also tested with the reference reporting tool from inmon for sflow and
that shows the correct amount of bandwidth.
i also tried to have sflowtool deflect sflow to netflow to ntop and see
if that makes a difference, but it didn't..
what do i have to do to make ntop show me the correct bandwidth?
regards,
johannes russek

hello everybody,
i have a bunch of servers connected to a hp procurve switch which is
configured to sample the traffic and send sflow datagrams to ntop (which
it does).
ntop receives the sflow datagrams and collects them nicely, and
everything seems to work.
only that traffic ntop shows is waaaay too less.
for example, the http traffic it should see is constantly between 40mbit
and 60mbit, ntop only shows an average of 2.1k though.
i have set the sample rate to 1/20 and ntop correctly figured that out
(it's on the traffic overview page at the general interface statistics).
what am i doing wrong?
best regards,
johannes russek
