Luca... could you give some tips about where to code it?
Thanks in advance.

Yes, that's it! To get a more realistic output. Right now it's only
summarizing info from sampled packet (only reporting a few bits),
it's not performing any estimation about real traffic.
How I could achieve that?
You need to code this into the sflow plugin and expand each packet by
the sampling rate. Is this something you're willing to do?
It is something that is already done, in this way, by some others of
your competitors (like InterMapper Flows). They simply multiply
received sFlow info by the sampling rate (and it gives to you a more
approximately global vision of real traffic).
So... what I should modify then on the sflow plugin?
Thanks a lot in advance for your help Luca.
Cheers,

Cheer,

you basically would like ntop to scale up numbers based on the
sampling rate?

Hi everybody:
I'm using nTop as sFlow collector.
My switches are sending sFlow sampling packets at 8192 sampling rate.
I would like to know how I could do to show real averages/rates on
summary reports, taking into account this "sampling rate". (Right
now reports seem to show summarized traffic as if it was captured
1 per 1 packet. They only show a few bits of traffic averages).
Thanks in advance.
Fernando.
