▼ View the System Message Log Files

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 message file is automatically created. The original contents of the messages
file are rotated to a file named messages.0. Over a period of time, the messages are
further rotated to messages.1 and messages.2, and then deleted.
1. Log in as superuser.
2. Type:
# more /var/adm/messages
Or, if you want to view all logged messages, type:
# more /var/adm/messages*
