Network monitoring with FreeBSD

[Kurt Buff]

If this belongs on a different list, please let me know...

I've long used ntop, but the current version in ports is missing a
feature that I found incredibly useful, and I'm seeking an
alternative.

I'm running several small FreeBSD 9 boxen monitoring my HP switches on
their mirror ports, and ntop 3.x could give the the top 3 talkers when
I clicked on a graph of the network load statistics, but under 4.x
that no longer seems to be the case, and 5.x isn't in the ports tree
yet.

I'd love to dive deeper into who is talking, and what traffic is
passing on my network, and I'm pretty dedicated to using FreeBSD, as
I've not liked any Linux I've ever touched.

I've perused ports/net and ports/net-mgmt, and there are a bewildering
number of options. If anyone has recommendations, I'd like to hear it.
