syslog.conf(4)syslog.conf(4)NAMEsyslog.conf - syslogd configuration file
SYNOPSIS
facility.severity destination Where: Is part of the system
generating the message, specified in /usr/include/sys/syslog_pri.h.
See also the syslogd(8) reference page. The severity level, which can
be emerg, alert, crit, err, warning, notice, info, or debug. See
/usr/include/sys/syslog_pri.h.
The syslogd daemon logs all messages of the specified severity
level plus all messages of greater severity. For example, if you
specify level err, all messages of levels err, crit, alert, and
emerg or panic are logged. A local file pathname to a log file,
a host name for remote logging or a list of users. In the lat‐
ter case the users will receive messages when they are logged
in. An asterisk (*) causes a message to be sent to all users
who are currently logged in.
DESCRIPTION
The /etc/syslog.conf file is a system file that enables you to config‐
ure or filter events that are to be logged by syslogd. You can specify
more than one facility and its severity level by separating them with
semicolons.
You can specify more than one facility logs to the same file by sepa‐
rating the facilities with commas, as shown in the EXAMPLES section.
The syslogd daemon ignores blank lines and lines that begin with an
octothorpe (#). You can specify # as the first character in a line to
include comments in the file or to disable an entry. The facility and
severity level are separated from the destination by one or more tab
characters or spaces.
If you want the syslogd daemon to use a configuration file other than
the default, you must specify the file name with the following command:
# syslogd -f config_file
Daily Log Files
You can specify in the /etc/syslog.conf file that the syslogd daemon
create daily log files. To create daily log files, use the following
syntax to specify the path name of the message destination:
/var/adm/syslog.dated/ { file} The file variable specifies the name of
the log file, for example, mail.log or kern.log. If you specify a
/var/adm/syslog.dated/file path name destination, each day the syslogd
daemon creates a sub-directory under the /var/adm/syslog.dated direc‐
tory and a log file in the sub-directory, using the following syntax:
/var/adm/syslog.dated/ date / file Where: The date variable specifies
the day, month, and time that the log file was created. The file vari‐
able specifies the name of the log file you previously specified in the
/etc/syslog.conf file. The syslogd daemon automatically creates a new
date directory every 24 hours and also when you boot the system. The
current directory is a link to the latest date directory. To get the
latest logs, you only need to reference the /var/adm/syslog.dated/cur‐
rent directory.
