Hello all,

Each end day i'm generating reports using flow-stat -f11.
That's the script that I use:

#!/bin/sh

one_day_ago=`/bin/date --date='1 day ago' +%Y%m%d`
rep_flows_courant=`/bin/date --date='1 day ago' 
"+/export2/netflows/%Y/%Y-%m/%Y-%m-%d/*"`

/usr/local/netflow/bin/flow-merge $rep_flows_courant | 
/usr/local/netflow/bin/flow-nfilter -f /usr/local/scripts/nfilter.cfg -F backupmatch | 
/usr/local/netflow/bin/flow-stat -f11 > /export2/netflows/flow-stat/$one_day_ago.log

Not sure if its the best way but it was setup that way by another collegue that left.
I'm my filter file :
filter-primitive backuphosts
  type ip-address
  deny x.x.x.x
  deny x.x.x.x
  deny x.x.x.x
  default permit

filter-definition backupmatch
  match ip-source-address backuphosts
  match ip-destination-address backuphosts

I think that's pretty basic.

So each day I get these values and at the end of the month with these values I can 
calculate
the bandwith used by each machine on my network. From my calculation one of the 
machine generated
257gig for Janurary. So far I think everything is fine.


Where my question comes is that recently I generated a report for a single machine to 
get a breakdown of the
traffic for that machine with all the ports for Janurary.

I've went into the directory of the flows and i've run that command :
/usr/local/netflow/bin/flow-cat */* | /usr/local/netflow/bin/flow-nfilter -f 
/usr/local/scripts/filter_ncc.cfg -F ncc | /usr/local/netflow/bin/flow-stat -f7 -s2

That's the filter file used :
filter-primitive ncc_host
  type ip-address
  permit x.x.x.x (Server)
  deny x.x.x.x  (Backup machine)
  default deny

filter-definition ncc
  match ip-source-address ncc_host
  or
  match ip-destination-address ncc_host

So this gives me all the ports with the bytes transfered for the given day for all the 
ports UDP or TCP.
So basically if I put all these lines in excel and do a SUM of the column bytes, and I 
get 546gig for January.

Why is there a difference in the values ? flow-stat -f11 gives me 257gig and flow-stat 
-f7 546gig.
Is there something that I've done wrong ?

Thanks for any help !
