Tools for monitoring traffic to specific websites

["Research Lookup" <infolookup () gmail com>]

Hello all,

 I am trying to monitoring the daily web traffic to sites a few
specific web sites, we are using a  proxy server to block and allow
access to various sites, however the server is not capable of meeting
this request. I was wondering if there is an application I can use to
monitoring say the daily or weekly traffic going to www.example.com,
and www.test.net?
