rsyslogd

CentOS 5.2に含まれるrsyslogdはちょっと古いけど、面倒なのでこれをさくっとインストール。

# Log all kernel messages to the console.
# Logging much else clutters up the screen.
#kern.*                                                 /dev/console

:programname, contains, "dhcpd" /var/log/dhcpd.log
:programname, contains, "dhcpd" ~

# Log anything (except mail) of level info or higher.
# Don't log private authentication messages!
*.info;mail.none;authpriv.none;cron.none                /var/log/messages

# The authpriv file has restricted access.
authpriv.*                                              /var/log/secure

# Log all the mail messages in one place.
mail.*                                                  -/var/log/maillog


# Log cron stuff
cron.*                                                  /var/log/cron

# Everybody gets emergency messages
*.emerg                                                 *

# Save news errors of level crit and higher in a special file.
uucp,news.crit                                          /var/log/spooler

# Save boot messages also to boot.log
local7.*                                                /var/log/boot.log

programnameでログファイルを分離できるっていうのが素晴らしい。

ファシリティ不足な方にぜひw
