The RD pulls the server's access logs into the database; it attempts to not infringe on user privacy too severely. Hence, it goes some way to pseudonymise IP addresses and let people opt out. You should run bin/dumpLogs.sh now and then. After download, run bin/pseudonymize.py manually once. When running, the RD does that by itself. To make sure the RD is loaded even when it's not immediately accessed, add logs/logs to your /etc/gavo.rc's [web] preloadRDs config item.
