Inspired by this, I wrote two Munin plugins using OpenBSD Pf monitoring Ipv6/Ipv4 traffic ratio.

I am using it on my router and my Peertube instance.

You can have a look at the result here. This is the current ratio of ipv6 traffic on my PeerTube instance.

Here is the traffic, in and out separated in colors.

Code is available on framagit or in my git repository :

git clone git://blackblock.22decembre.eu/pf-ipv46-packets.git
