I'm not sure of your specific application, but it sounds to me like netflow/sflow exports would be the most scalable way to do this.
For small applications, ntop or bandwidthd can do this. http://www.ntop.org/products/ntop/ http://bandwidthd.sourceforge.net/ Cheers, jof On Mon, Apr 8, 2013 at 12:51 PM, Deric Kwok <deric.kwok2...@gmail.com> wrote: > Hi all > > Do you know any opensource program bandwidthgraph by ipaddess? > > Thank you
