LAN bandwidth utilisation metrics

[NachT]

Hey all =]

I'm going through a bit of a metrics phase at the moment, and thought I'd post here before going off doing my own thing.

What I'm after is a solution that will:
- Display the bandwidth utilisation of each device on my network.
- The metrics provided would have to be granular, i.e. I can see how much bandwidth each device used right down to the day of a month.
- Be able to distinguish between the LAN and WAN bandwidth (WAN traffic is what I'm really after)

Bonus points for:
- Checking number of unique connections made over a day/week/month
- Most common port used
- Most common remote connection, and how much bandwidth to said host.

At the moment, the best solution I'm currently thinking of involves a PfSense gateway to route all the traffic on the LAN through, then somehow capture that data to be display within something like Grafana/Chronograf. I 'could' potentially use Telegraf on the gateway itself, but I'm really not sure it would capture each unique device on the network.. just the NIC as a whole (I'm assuming).

So if anyone has anything similar to the above in place, I'd really much appreciate any feedback =]

Oh, just in case it helps. My current network layout is a Ubiquity Switch, and a Ubiquity AP. The gateway on my network at the moment is the ISP provided BT Home Hub (wireless and DHCP disabled)

Thanks for that suggestion Rain, OPNSense looks pretty neat! I'll spin one up and give it a whirl =]

One of my Linux boxes handles DHCP (Planning on migrating to Windows DHCP once I get my head around it and IPv6).
