thanks for the help. We figured out the issue. The archive cronjob didn't run. The "useraccount" which run the script was not allowed to do this. Unfortunatly, we didnt got any error message. The logfile was empty aswell. It actually was just luck that we run the script as "root". Once it was done, the data was shown in Piwik.
My issue is solved now.
