Re: NTP monitoring
NTP should be pretty much self healing. You might want to review syslog entries just to assure yourself that all is well:
"grep -i ntp /var/adm/syslog/syslog.log"

Re: NTP monitoring
If you have any doubts about your setup use this command to monitor connection
ntpq -p
The "reach" value will move towards 377 if the connection is reliable.
Also check for the /var/adm/syslog/syslog.log file for ntp logs.
and xntpd is the daemon should be always running

Re: NTP monitoring
Look for entry's in your syslog, like "Lost connection to stratum" if you do not find them in your syslog you are pretty save.
Hope it helps,
Robert-Jan.

Re: NTP monitoring
We see synch lost and resynch messages as well. I suspect that this is completely normal. For ongoing monitoring, I would suggest a cron job that greps syslog for ntp messages once a day and emails the output to you. You could get fancy and check for a synch lost without a corresponding resynch, but a little manual review would also work without too much effort.
