Thanks again for your reply falko. I've solved my problem using "Analog". It takes in account the parameters when doing the statistics and it also generates plain text tabulated files:
eqs %bytes last time file
32674 12.38% 1/Aug/05 04:15 /printMag.php
1655 1.19% 1/Aug/05 03:55 /printMag.php?num=137&lang=1
1563 0.46% 1/Aug/05 03:18 /printMag.php?num=141&lang=1
1456 0.53% 1/Aug/05 03:14 /printMag.php?num=145&lang=1
Hope this helps to anybody who has the same problem.
