In most of cluster, the compute nodes do not have direct networking to access the external or corporate NTP servers.
Then it would like the head node to act as a broker, it means MN get time from external ntp server and all CNs sync time from MN.
To achieve this , You need to set `site.extntpservers` for it, and run `makentp`
If your CNs could access the external ntp server directly via provision network, you can also set `site.ntpservers`, and those ntp servers will be configured on CNs by `setupntp` postscript after it provisioned
For syslog, xCAT did not like to forwarding to external syslog server by default, as it is hard to debugging issue when errors during provisioning.
So by default it will collect all syslogs. But you can still configure your rsyslog by some rules on your MN to forward to others syslog server.

Subject: [xcat-user] Network Log servers and NTP servers.
Date: Wed, Nov 29, 2017 7:55 PM
Hello,
I'm slowly configuring my xCAT installation further, and want to define
log servers and NTP servers to my CNs during installation.
As far as I understood, if undefined, xCAT MN is used as NTP and log
server if none defined, however our cluster have a central log and NTP
server.
How can I add these servers in addition to the list so, the CNs have two
NTP server addresses and two log server targets?
Thanks in advance,
Hakan
