Those files are normally referred to as stats rather than logs.

The ntp.log file contents depends on logging options, normally set at the
very top of ntp.conf to:

	# Log everything
	logconfig =allall

as ntpd is not very chatty, except after startup, and when problems happen
if you have relevant logging enabled.

For your release "By default, logconfig output is set to allsync" (from
which will only log sync events, so your log may not be appended often.

See current stable doc http://doc.ntp.org/4.2.6p5/decode.html about events,
as your release docs do not include this info.

Even better, update to current stable from download sources, keep your
current config file (with the change above), and many problems will

Take care. Thanks, Brian Inglis
