You obviously need a place to stand.  If you are running ntpd on that system, 
you can use it to watch various other systems.

Start by turning on logging.  If you think in terms of request-response 
pairs, rawstats will get a line for each response.

Then add each system you want to monitor to your ntp.conf with a server line 
that includes noselect.  That will go through all the request-response dance, 
log the result, then ignore it.

The results will also show up in ntpq -p
