Go With The Flow (GWTF) is a plugin I'm actively working on, so there are frequent updates.
It's freely available, so have at it.

I started it because I wanted to see live traffic graphs showing host names, not IP addresses. I tried ntopng (didn't like it) and ZenArmor (required a license), the built-in graphs and Top Talkers didn't show what I wanted (and showed IPs). So my live graph and details page shows local and remote host names, it pulls local ones from dnsmasq and sniffing dns etc. DPI is going to be worked on this week.
My needs are simple, my home network is simple, I'm not interested in pushing the limits with a home lab, so I'm not trying to compete with the full enterprisey features that other plugins have. That said, I'm open to adding features that may be beyond my direct needs.
Anyway, have a play. It's free and easy to install.

I know I could download the package and extract it but not having the source code browsable (since its in a private repo) is a bit meh.
