[CentOS] [SOLVED]: NIC traffic monitoring, recording and reporting software?

I learned a great deal about Linux based automated system and
network monitoring these past 24 hours.  However, when I went to
implement an iptables solution per the suggestion of Filipe
Brandenburger, I discovered that Webmin already has a script for
this setup and ready to go. So, I have enabled that feature on the
eth0 port of the remote host and this seems to give me what I need,
for now anyway.

Many thanks for all the suggestions and references.  Those that I
have not already looked into and read I will keep against a future
need.

Regards,
