Hello.
I use openwrt for a month now.. very cool stuff :-)
I developed a(nother) little script based on "Connection Tracking IP QoS / Bandwidth Monitor - https://csdprojects.co.uk/ddwrt/" for DD-WRT (thanks to author).

It allows a per-IP bandwith monitoring.
I'm not a sysadmin, do not be too hard with me :-) I just decide to publish it for the community

Bye bye

The pie chart that gargoyle has is fancy, but this one is really cool.  Just what I really need.  Thank you.

It says the package needs Need QOS Uplink and Downlink configured. OpenWRT has a package called SQM scripts (feeds/packages/net/sqm-scripts) to perform QoS. Will your program still work?

Just add the file
touch /etc/config/qos

config interface wan
    option upload       9300
    option download     47000

Nice work by the way

Thanks for your work. It works under PandoraBox on my Xiaomi Mini.

Please Can you help me, how can i add "button" into LUCI Web interface just with link to routerip/wtBRMon/ ?

Thanks!
