In /etc/syslog.conf, add the below. You can change this according to your requirement.
mail.debug /var/log/mail.log
kern.debug /var/log/kern.log
syslog.debug /var/log/syslog.log
daemon.debug /var/log/daemon.log
local2.debug /var/log/sudo.log
As AIX doesnt have logrotate daemon running, you have to make syslog handle this. Something like this ..
mail.debug /var/log/mail.log rotate size 100k files 2 # 2 files, 100kB each
local2.debug /var/log/sudo.log rotate size 500k files 2 # 2 files, 500kB each
kern.debug /var/log/kern.log rotate files 12 time 1m compress # 12 files, monthly rotate & compress
…
Make sure to restart syslogd.
# refresh -s syslogd
