I use Icinga2 (nagios fork) for that.  NTPsec prolly just needs to
document that existing usage.

I can see us including a nagio/icinga2 plugin for that, but the
existing plugins have worked great for me for over a decade.

Here are the existing plugins:

/usr/lib64/nagios/plugins/check_ntp_peer
/usr/lib64/nagios/plugins/check_ntp_time

Yeah.  Here are the existing options.
spidey ntpsec # /usr/lib64/nagios/plugins/check_ntp_peer

Usage:
 check_ntp_peer -H <host> [-4|-6] [-w <warn>] [-c <crit>] [-W <warn>] [-C <crit>]
       [-j <warn>] [-k <crit>] [-v verbose]

spidey ntpsec # /usr/lib64/nagios/plugins/check_ntp_time

Usage:
 check_ntp_time -H <host> [-4|-6] [-w <warn>] [-c <crit>] [-v verbose] [-o <time offset>]
/usr/lib64/nagios/plugins/check_ntp_time

Seems to me that's reinventing what is already a very sturday, well
trusted and well deployed wheel.
