Logging function

The NTP components store their logging information in the /var/adm/syslog file.

The ntp entries of this logging file have the following basic format:

<date> <time> keyword ntpd[pid]: <message text>

The date and time is followed by a keyword that classifies the message.

The NTP uses the keywords LOG_INFO, LOG_NOTICE, LOG_DEBUG and LOG_ERR.

The classification is followed by the process name (here ntpd) with information on the relevant process ID (PID). If no valid PID is available for the message output (e.g. for a message output during the daemon startup procedure), an empty parenthesis expression is displayed. The actual message text then follows.

Furthermore, logging entries are by default written to the /var/adm/ntp.log file.
