настройка syslog-ng

Подскажите, как настроить syslog-ng, что-бы в лог /var/log/messages не сыпались такие сообщения:

syslog-ng[1768]: Log statistics; processed='center(queued)=844', processed='center(received)=487', processed='destination(d_boot)=0', processed='destination(d_auth)=11', processed='destination(d_cron)=17', processed='destination(d_mlal)=0', processed='destination(d_kern)=428', processed='destination(d_mesg)=384', processed='destination(d_cons)=0', processed='destination(d_spol)=0', processed='destination(d_mail)=4', processed='source(s_sys)=487
