Getting stats on how much data we take from a neighbour

Squid users,
        From the stats packages I can gleen how much data our neighbours
request, and ultimately take, from the squid cache we run.
        However, what I'd like to know is how much data we request ourselves
and obtain, from our neighbours.
        Is there an easy way to do this? ie: any stats packages, debug
levels I should turn on etc.

Rich.
