9.28.3 Discussion
This script simply iterates through all syslog
facilities and priorities, sending a message to each combination.
After running it, examine your log files to see which messages ended
up where.If you don't want to hard-code the facilities and
priorities (in case they change), write an analogous program in C and
reference the names directly in
/usr/include/sys/syslog.h.

logger(1), syslogd(8), syslog.conf(5).syslog-ng ("new
generation") is a more powerful replacement for the
standard system logger. If you crave more features or are frustrated
by limitations of facilities and priorities, check out http://www.balabit.com/products/syslog_ng.
