@virgiliomi:
The Monitor graphs don't provide that data anymore. RRD is not the most accurate way to be tracking total traffic anyway, as it loses accuracy as soon as 8 hours because it averages data to reduce the amount of data needed to be stored long-term. If you want to track this using RRD's data, you can add the "RRD Summary" package, which will add an item to the Status menu allowing you to see the RRD total traffic numbers with some basic settings.
jdillard has been working on bringing vnstat over to the 2.3.x world as a more accurate way to track total traffic, providing graphs for a variety of time periods (I believe vnstat can show daily, weekly, and monthly graphs, though what he will have available, I don't know). A couple of his posts over in this thread include links to screenshots of the graphs.
Ok sounds good, thanks for the info!
