Those are all good suggestions.  Juniper (those with an IP II ASIC)
also has the "FIREWALL-MIB" which can be used to monitor traffic that
matches filter list rules.

It would also be nice if popular FTP servers came with a small SNMP
agent that would expose these statistics.  That might be a good term
