Accounting For pppoe-users

Hi
Is there a way to view the usage of bandwidth on a per user basis for pppoe-users ?

Thx for any help

You can either use radius accounting or /ip accounting (lists by username)

/ip accounting also has a web interface so you can automate fetching

Thanks for your response I do prefer not to use Radius Accounting at this stage so I think I will use IP accounting. Please could you tell me where to access the webinterface ?
I mean it is http://myrouter/ but what directory should I look in ?

Thank you
