rsyslog에서 hostname 대신에 IP address 로 기록하는 방법

rsyslog를 가지고 로그서버를 구축하고 있습니다.

Jun 18 14:40:23 com20 smartd[4045]: Device: /dev/sdf, opened
Jun 18 14:40:23 com20 smartd[4045]: Device: /dev/sdf, not found in smartd database.

이런식으로 잘 기록이 되고 있는데요. 호스명 대신에(com20, hadmin1) IP address로 남기고 싶은데
관련된 옵션을 찾기 어렵네요.

로그서버의 설정은 아래와 같습니다.

[root@com27 ~]# cat /etc/sysconfig/rsyslog
SYSLOGD_OPTIONS="-m 0 -r -x"
KLOGD_OPTIONS="-x"

[root@com27 ~]# cat /etc/rsyslog.conf
