[ntp:questions] Will ntpd tell me if it encounters problems?

Hi all,

I am using the default ntpd setup in plain redhat box. Default
settings except for specifying a nearer time server.
Everything seems fine (ntpq pasted below), and it has been left alone
for months.
Said box hardly receives human attention, and is depended on for time
sync by a couple hundred local machines.

My question is: how would I know if ntpd has problems. I'm thinking of
some kind of alert when ntpd is unable to contact any good time
servers, for example.

# ntpq -np
     remote           refid      st t when poll reach   delay
offset  jitter

Assume the above is healthy?

Thanks very much.
