Bandwidth usage of EACH protocol (Windows serv er, linux server, Cisco routers and firewalls)

[Tedman Eng]

You should probably look at an entierly different application for traffic
analysis.  Nagios is more suited to service-based monitoring and alerting.
Per-protocol analysis is the realm of a log parser and/or network sniffer.
Nagios would mostly be useful in raising alarms if one of these such
programs detected traffic beyond a certain threshold.

Some programs to investigate would be:
ntop, IPTraf, EtherPeek, EtherApe, etc.
