The error logging daemon, syslogd, automatically records various system warnings, errors, and
faults in message files. These messages can alert you to system problems such as a device that
is about to fail.
The /var/adm directory contains several message files. The most recent messages are in
the /var/adm/messages file. After a period of time (usually every week), a new messages

messages.3, and then deleted.
