Actually, Analog said that your web server only recorded 4297 requests.

It's not immediately obvious how a request for 468x60.jpg is supposed to trigger the update process you describe above - .jpg is usually a static file type. But a useful sanity check would be to see what Analog shows as the number of requests for the page that the .jpg file is embedded in. Is it more in line with the 4297 number or the 100121 number?

Steve,

Could it be that its due to 'repeat visitors'? - check to see if '304ISSUCCESS' in your analog.cfg is set to OFF. I had a different php/db problem where files were downloaded from the database and even though the file was different the browser did not 'refresh' it - that could be the cause of a '304'.

Also, have you any excludes setup on the analog.cfg (I made that mistake once)

I showing some odd stats in my analog, as compared to a simple "impression
tracker" I have scripted on a page.

Quite simply, I pull a random image from a database and display it on the
screen, then I update that database record by adding 1 to the impression
count. Very simple.

1. get random image from database
2. display image
3. update database impression count (+1)

But I get very skewed results, here are my impression counts for one
particular banner through my simple script:
Impressions: 100121

Yet Analog shows this:
4297 0.16% 19/Mar/08 15:50 /banners/468x60.jpg

So I've recorded over 100,000 impressions, but analog only recorded 4297
requests.

Anyone have an explanation or general direction I can look to sort this out?

Analog only reports what's in the web server logfiles. I would have a
look in the logfiles to see what's being reported when you get one of
those images.
