Hello all,

Great tool, very useful.

I'm trying to understand the total bytes per time bin collected by nfacctd.

The problem I have is a calculated bandwidth per time bin (5 minute
intervals) does not match the calculated bandwidth from SNMP byte counters.

On one link, NFacct data is always more than what SNMP data reports.  In
some cases it is by a factor of 2.  On another link it is usually below
the average bandwidth however there are some instances of the described.

If anything, I would expect the calculated bandwidth to always be less
than what SNMP reports since I am limiting NFacct collection to a minb
value.

I suspect maybe this is something to do with the accounting time window
within nfacct and the netflow timers.  I'm looking through the source
code for clues, but maybe someone has seen this before or can point out
my mistake ?


Regards,

--Jason
