I want to monitor NTP error message to catch synchronization fail like network unreachable, server error etc..
When I add logconfig =allall in /etc/ntp.conf, and restart ntpd, trying to get more information when error occurs, but the output information is not enough for me to monitor.
But, if I run ntp in debug mode, like "ntpd -u ntp:ntp -p /var/run/ntpd.pid -g -D 4", I can get more detail information.
Could I just modify ntp config file to do the same thing as debug mode?
By the way, logconfig seems not written on man page.
Thank you!
