[Xymon] NTP requirement for Terabithia xymon RPM - RHEL/CentOS 7?

[Brian Scott]

Hi,

The ntp test uses the ntpdate command:

> Command: ntpdate -u -q -p 1 192.168.192.1 2>&1
>
> server 192.168.192.1, stratum 3, offset 0.000055, delay 0.02580
> 18 Aug 12:19:03 ntpdate[75689]: adjust time server 192.168.192.1 offset 0.000055 sec
It shouldn't matter if the system is using chrony for timekeeping
because ntpdate with '-q' is a simple ntp protocol query that doesn't
attempt to change anything.

You may be able to cook something up with the chronyd command using the
option '-Q' but it looks quite messy to do.

Cheers,

Brian
