Hello Robin,
You can draw you own graphs (based on subnet or even AS) if you create a new
profile or channel-lists and if you specify there in the filter section
something like 'net 10.0.10.0/24'. To be more effective (depending on what
you need), you can create shadow profiles (to save disk space).
I also recommend that you create these profiles/channel-lists per router and
in the filter section specify the input/output interface (with inif 5 or
outif 22). You can get the actual numbers by looking for the interface snmp
indexes on the router (show snmp mib ifmib ifindex on cisco).
To draw graphs based on source/destination AS, use as filter 'src as 101' or
'dst as 202'. Note that for this to work, your flows should have these
fields filled in (from experience, I can say that you can get less traffic
than the real values because of router bugs - not all flows have the AS
fields filled up).
To browse your flows and see input/output interfaces and input/output AS,
you can use this output line modifier:
fmt:%ts %td %pr %sap -> %dap %pkt %byt %bps %pps %in %out %sas %das %fl
I have been working for some time developing a plugin that can do these
graphs and more, but I'm afraid I can't release it yet, because of my
company's policy (but I haven't given up hope).
Hope it helps,
Good luck,
Adrian Popa

Any way to graph bps by subnet with nfdump and nfsen?
Also, the total bps currently being seen by nfsen is much lower than I
would expect. Is there any problem with the flows generated by fbrobe
sent to an nfsen/nfdump install?
Thanks and regards,
Robin
