Yes, specifically when you quote my signature.

I snipped methods for gathring information that is available through
SNMP already. But is this information useful?

Specifically, I don't care about fragmantion and packet loss of all
packets. Just of those in the relevant streams.

ntop tries to keep rtack of all packets and then give some useful
details from that. It has a reputation for being a memory hog. A simple
apt search on my system shows up a package called "darkstat" which
describes itself as "known to be smaller (in terms of memory footprint)
and stabler than ntop."
