The Service Management Facility (SMF) feature of the Oracle Solaris logs the status of its services per service. Many services, such as auditing and Secure Shell, write their own logs. The syslog or rsyslog daemon writes a centralized log that can inform and warn administrators of critical conditions in many services. For example, auditing can be configured to write summarized auditing records to syslog. See the syslogd(1M) and syslog.conf(4) man pages.
