Package: nagios-plugins
Version: 1.4-6
Severity: normal
Check_ntp calls "ntpdate -q $host", which determines the offset of the
nagios host from $host. It then has this gem:
$offset = $2;
# An offset of 0.000000 with an error is probably bogus. Actually,
# it's probably always bogus, but let's be paranoid here.
if ($offset == 0) { undef $offset;}
$ntpdate_error = defined ($offset) ? $ERRORS{"OK"} : $ERRORS{"CRITICAL"};
There's two problems: the first is that the comment doesn't match the
actual code; there's no check for an error, just the assumption that
"offset == 0.0" is an error.
The second problem is that if "$host" is "localhost" (i.e the host
running nagios), it's completely legitimate that the offset is 0 --
that's the whole *point* of ntp. As a practical matter, it tends to
flip between 0 and very small values, so nagios is continually swappign
between OK and CRITICAL.
For that matter, there's a third problem: the whole ntpdate check is
wrong headed. It compares the time on the nagios host to the time on the
host being monitored, which is irrelevant to the quality of time on the
remote host. The ntpq check is the proper one; the ntpdate check should
be removed entirely, which, since ntpdate is deprecated, would be just
as well.

Steve

hi jeroen, steve,
numerous fixes to check_ntp have been included since 1.3.x, so i'm going
to go out on a limb and say that the check_ntp problems are resolved.
if they are in fact not, we can reopen the bug reports :)
