RE: Usage Graphing per Subnet

Hi All, I have a requirement to plot a usage graph per subnet. As an
example.

I have a 192.168.1.0/24 subnet divided among 32 customers where each
one will get a /29 [ 192.168.1.0/29 => Customer A ; 192.168.1.8/29
=> Customer B etc... ] ...

Is there any tool to graph the usage of entire /24 subnet ???

I use nfdump/nfsen for this sort of thing.  It requires netflow export on your devices.  I then I create a shadow 
profile for each subnet I wish to chart.
