pwebstats

Hi,
I have just installed pwebstats (succesfully) to analyse my logs. Specifically
what I am after is the Mb that are fetched from the internet on a daily basis.
I see two figures:
"Bytes sent for proxy requests"
"Bytes sent for cache requests"

The total of these appears to be the total Mb served, but is one of them the
figure I am looking for?

TIA
