SMF records information about significant restarter actions, method standard output, and standard error output to /var/svc/log/service:instance.log for each service instance. Hyphens are substituted for forward slashes in the service name in the log file name. The svcs command with the -L, -l, or -x option shows the full path name of the log file for the specified service instance. The svcs -xL command shows the last few lines of the log file and tells you to use the svcs -Lv command to view the complete log file. The svcs -Lv command displays the complete file, which could be quite long. If you prefer to view the log file in an editor or view just the last n entries, for example, operate on the output of the svcs -L command.
The following example shows how to use the log file to investigate why the service shown in the svcs listing is temporarily disabled.

Other log files that you might find useful include the log for the master restarter daemon and the system log. To see the log file name and view the log file for the svc.startd restarter daemon, use the service name restarter with the svcs command. To see the log file name and view the log file for the syslogd system log daemon, use the service name system-log.
$ svcs -L restarter /var/svc/log/svc.startd.log $ svcs -L system-log /var/svc/log/system-system-log:default.log /var/svc/log/system-system-log:rsyslog.log
