check_ntp

[Vincent Aniello]

I am receiving a lot of critical alarms from the check_ntp plug-in.
 
Below is the verbose output from the plug in:
 
[root at prblkc01b etc]# /usr/local/nagios/libexec/check_ntp -H localhost

Server for ntp probably down

Can someone tell me what exactly the plug in is looking for and why does
the output above cause an error?
 
Thanks.
