trouble while trying page-accounting

Dear all,

I tried to use Pykota for pageaccounting but somehow ran into trouble. Having 
successfully installed pykota i realized that is doesn't count any page 
printed. Maybe it's a problem with the Postgresql-storage. Even after printing 
some pages repykota claims i hadn't printed any page. (any ideas? Help is 
warmly wellcome)
So i thought about writing a simple and mybe quite unreliable filter myself. 
This filter should look up the number of pages the user has allready printed 
from the page_log file then take the number of pages to print via grep -c 
showpages and compare them with a quota stored in some (ascii?) file.
So far for the idea. But sadly enough I don't know how to do it. by now i only 
managed go aquire the number of pages a user has printed from the page_log. How 
can i find out which user has sent which job and the name of this job?

sorry for asking these stupid questions, but i would be nice if anyone could 
help me.

   best regards,
