Hi,
All machines talking to my main NTP node are giving errors back to the
Nagios check_ntp command.
What's the best way to troubleshoot this? Any useful commands?

Here are some of the warnings from the pool of servers I have running:
NTP WARNING: Offset 5.549596 sec > +/- 2 sec, jitter 9.111 msec
NTP WARNING: Offset 5.560099 sec > +/- 2 sec, jitter 9.534 msec
NTP WARNING: Offset 5.596052 sec > +/- 2 sec, jitter 10.068 msec
When I run ntpq -p I get:
/usr/sbin/ntpq -p

pps stability: 512.000 ppm
pps jitter: 0.0002 s
