Hello,

I've been running Analog for a few months now and I came across a funny thing showing up in the report. Analog analyzes all data in the Apache log, including file size. The last analasys is from 17-03-2005 to 26-05-2005 (70 days). And that makes it even more obvious that something is not right.

The statistics of this morning said the total data transferred was 4.01 Gigabytes. However when I checked the page again in the evening, it suddenly said 1.18 Gigabytes. Then I started figuring and calculating, and I figured that it crosses the 4GB data transferred 2 times per month. Why does analog "reset" the counter after 4GB of data? is it unable to calculate any further?

How can I fix this problem? or is it a bug?
I run Analog 6.0 on Windows 2000AS on the Apache logs.


Plausible guess, but in fact wrong. There is no such limit. (The number of bytes is stored in a double, not an unsigned long). You can try it out with this logfile:

statslab.cam.ac.uk - - [31/Dec/1999:10:11:12 +0000] "GET /sample.html HTTP/1.0" 200 3234000000 "http://referrer.com/"; "Mozilla/4.0 (compatible; MSIE 4.01; Windows 98)" statslab.cam.ac.uk - - [31/Dec/1999:11:11:12 +0000] "GET /sample.html HTTP/1.0" 200 3234000000 "http://referrer.com/"; "Mozilla/4.0 (compatible; MSIE 4.01; Windows 98)"

You should see 6.02 GB transferred.

So what is going wrong? Maybe your logs are being rotated, so you're losing some old logs from the analysis periodically?
