Hi all, I'm new with rsyslog

Normally a log record has the format:
Apr 18 15:54:15 [[i:3e1siti8]myhostname[/i:3e1siti8]] sshd[22594]: Failed
password for root from 10.30.12.109 port 42849 ssh2

but now I want to log in form:
Apr 18 15:54:15 [[i:3e1siti8]myIP[/i:3e1siti8]] sshd[22594]: Failed
password for root from 10.30.12.109 port 42849 ssh2

This mean it use IP instead of hostname. So can anyone show me how to do
this ?

Thank you very much.
