My original post was completely concerned on automating the process of spinning traffic throughput graphs. Are there any software packages that stand out that have the ability to differentiate throughput between v4/v6, as opposed to the aggregate of the interface? (I will continue reading docs of all recommendations, but this may expedite the process a bit).
That's a feature of the switch you are probing, not the monitoring suite per se. e.g. I have Cisco CPE that does count the difference : bcliffe-gw#sh int accounting | b Vlan1 Vlan1 Wired network VLAN Protocol Pkts In Chars In Pkts Out Chars Out IP 4587251 1137174268 4757409 3669014365 ARP 12595 755700 52409 3144540 IPv6 188872 20699030 223349 131947020 .... but these numbers can not be polled via SNMP, so the only way to graph this device is with an expect script and telnet access. Nice. :-) There is an ipv6MIB, with some interface stats defined under 1.3.6.1.2.1.55.1.6.1, but I do not know of a family of devices which supports this for sure. If your devices support Netflow9, then this -- whilst an extremely heavy/"kitchen sink" approach -- will give you any degree of granularity that you like. Not long term reliable, but if your v6 is presented via a tunnel, you could graph that tunnel interface ? Yuck, yuck (but we did measure some ipv6 traffic use (more than we expected actually) at a recent operational meeting in the UK) Please let us all know if you find something with good v6 snmp support.
