How to add parameters to get_user_audit_logs()

.rccontrol/community-1/profile/bin/rhodecode-api --instance-name=community-1 get_user_audit_logs

Funny thing is, that it gives me back a list of entries which only contains one particular user. Every element is for that user.
I am not sure why. If I got to the web interface and lookup the audit logs, I can see every user.
