Thanks for the suggestion, however:

I´ve used MRTG before, and it is an exellent program, but far to complex to apply here. We´re talking about 60 different DSL locations here. None of which have switches at all, just hubs, so there are no SNMP traps to collect there. NRG I´m not familiar with, but it looks pretty complex as well. I need something that is easy to set up and manage scince there are so many connections that need to be measured.
