Console and syslog Messages
Each time a significant event occurs, the syslog message logging facility enters
an error message into the system log, /var/adm/syslog/syslog.log.
Depending upon the severity of the error and the phase of system operation, the
same message might also be configured to display on the console. For more
information, see the syslog(3C) and syslogd(1M) man pages.
Status Messages
Several commands provide status information about devices or services, for
example, the FCode field from ftsmaint ls output. For a complete list of status
commands, see “Monitoring and Troubleshooting.”
