The primary logging for the most Linux/Unix OS platforms is sent to the syslog facility as configured in the /etc/syslog.conf file.
When debugging be sure "debug" priority messages are logged somewhere from /etc/syslog.conf
syslog debug Example:
Something like the following usually works well:
*.debug /tmp/syslog.out rotate size 100k files 4 or *.debug /var/log/messages
These will produce messages at debug priority that will be syslogged.
Restart syslogd#Following syslog changes, you will probably need to restart ot refresh syslogd. The process varies by OS Platform.
Linux and Solaris #
AIX#On AIX you can, usually use:
stopsrc -s syslogd;startsrc -s syslogd
