check_ntp has been deprecated for many years now, you should be using
check_ntp_time & check_ntp_peer instead.
Does the issue also occur with those?
Quick check, just replacing check_ntp with one these:
* check_ntp_peer sends a NTPv2 package, no reply from the server.
* check_ntp_time: Same as with check_ntp, works with a jessie ntpd,
fails with a stretch ntpd.
This is from a stretch system:
$ /usr/lib/nagios/plugins/check_ntp_peer -H localhost -v
3 candidate peers available
synchronization source found
Getting offset, jitter and stratum for peer d53
parsing offset from peer d53: 0.000473
NTP OK: Offset 0.000473 secs|offset=0.000473s;60.000000;120.000000;
Does your /etc/ntp.conf include the IP for your monitoring system to
allow it to interrogate the ntp server more closely?
