He woouldn't, but your original question was "if 1000 different people/hosts view our graph on page XYZ analog will show that we've got at least 1000 requests from 1000 individual hosts referred to us by the site XYZ?". Analog will tell you how many requests were referred from site XYZ, but it won't tell you how many individual hosts were referred from XYZ, because some of those hosts may also have been referred from PQR and from ABC as well. So if an individual user vists 3 different 3rd party sites, you'll have 3 requests in your log files, referred from 3 different sites, but Analog will only count 1 unique Host. > As for the second question I made an error.

Apparently, there > are some files on the site I'm not aware of. There is a command "REQINCLUDE PAGES" that will cause Analog to ignore anything that isn't a Page Request when it is generating the Request Report (or, to put it another way, it turns the "Request Report" into a "Page Request Report"). You can comment out that command to see all the requests, or you can look at the File Type Report to see what other types of files are being requested.
