This has the sound of network flow statistics collection via the kernel
and simple reporting/monitoring with nfdump.  nfdump is decidedly
non-graphical.  If you ever want pretty graphs and charts, nfsen
is a php webserver front-end for nfdump.

While I've been an nfdump/nfsen user, I'm just a some-time dabbling
