How to calculate an exact traffic values?

[alex116]

Hi all.

I need some plugin for calculating an exact traffic values. Can any plugin to do this?

I can see this values from Graph with Total Bandwidth, but there are exact values​​ only for the first few days, after then the values ​​are averaged up and I see no accurate data.

I need plugin for calculating accurate traffic, it may be without graph, only time period and total bandwidth.

Thanks.
