DescriptionField
Creator of the message, which can be auth, authpriv, cron, daemon, kern, lpr, mail, mark, news,
syslog, user, local0 through local7, or an asterisk (*) for all. These facility designators allow you to
control the destination of messages based on their origin.
Check your configuration before using a local facility.
Note

err, crit, alert, emerg, or an asterisk (*) for all. You can use none to disable a facility.

Destination for messages, which can be a filename, a hostname preceded by the at sign (@), or a
comma-separated list of users or an asterisk (*) for all logged-in users.

Step 1 Log debug messages with the local7 facility in the file /var/log/myfile.log by adding the following line to the
/etc/syslog.conf file:
debug.local7 /var/log/myfile.log
Step 2 Create the log file by entering these commands at the shell prompt:
$ touch /var/log/myfile.log
$ chmod 666 /var/log/myfile.log
