How to know how much packets or data flowing to shaped devices

[muthurajbharathi]

I want to render a live graph based on how much data or packets are flowing to devices which are shaped using atcd.

And also i need a info of packet drop along with packets or data flow. Please help me achieving this

All the info you need is in tracked in the Linux kernel on the wan and lan interfaces. A good starting point would be tcpdump.
