Monitor down/up realtime per client

I'm looking for a per client realtime bandwidth monitor integrated with luci. I once saw such an packge but I don't know it's name. It was a table with clients listed with according baudrate. It could be accessed under realtime graphs > "rate". Anyone knows the name?

I think it's luci-app-nft-qos.
It's a QoS tool, but it also provides realtime traffic rates.
