[mrtg] Re: Question about MRTG and backups

[Dana Hudes]

If you are running on your public network SNMP will not tell you anything of the destination IP address or port . You can still get some info with MRTG if you use iptables/ipchains because you can get the # of times the rule fires. I don't believe, however, ipchains can report volume but I haven't looked and I don't have that hooked up.
If you have a Cisco switch or router, or Juniper (and I *think* Extreme might support it too) you can
use Cisco NetFlow export and Flowscan. That uses rrdtool. Once you have everything in rrdtool
you can piece things together.

>From a network architecture perspective, I'd rather see you have a private backup network at the LAN level at least.
