/var/log/messages empty

[jarmo]

I'm confused, /var/log/messages is empty. FC15 
multi-user.target.wants]# systemctl status rsyslog.service
rsyslog.service - System Logging Service
          Loaded: loaded (/lib/systemd/system/rsyslog.service)
          Active: active (running) since Wed, 13 Jul 2011 17:20:03 +0300;

kmsg-syslogd.service (code=exited, status=0/SUCCESS)
        Main PID: 16110 (rsyslogd)

                  └ 16110 /sbin/rsyslogd -n -c 5

I get absolutely nothing into log. Nothing with command logger foo
does write nothing into messages.
Where to look solution?
