NTP Configuration Values
The NTP configuration dialog box contains the following fields:
NTP Configuration Values
|
|
|
|
NTP Address
|
The hostname or IP address of the NTP server/pool
|
|
Type
|
One of Server or Pool.
|
•
|
Server should be selected when the specified hostname resolves to only a single IP address, or an IP address is used. |
|
•
|
Pool should be selected when the hostname resolves to more than one IP address. For example, ntp.riscnetworks.com is a pool. A commonly used public pool is pool.ntp.org (https://www.ntppool.org). |
|
|
Status
|
This will display one of several statuses depending on the state of the appliance NTP client.
|
•
|
Enabled (Healthy) will show when the appliance is successfully syncing to an NTP server or pool. |
|
•
|
Enabled (Not yet synchronized) will show when NTP is enabled, but the appliance has not yet synchronized its time. It can occur for one of a few reasons: |
|
•
|
This may show for some time after a new configuration is applied or the appliance is rebooted. |
|
•
|
This may show if the specified NTP server/pool is not reachable due to a firewall or other connectivity issue. |
|
•
|
This may show if there is connectivity to the specified server/pool, but the local client is rejecting the provided time due to instability or inconsistency. |
|
•
|
Disabled (Hypervisor timesync in use) will show if NTP is disabled. |
|
•
|
Enabled (Degraded: using only hypervisor timesync; specified NTP server(s) are unreachable or unusable) will show on Hyper-V if the hypervisor host timesync is working but no remote NTP servers can be used. A likely cause here would be a firewall issue. If remote NTP connectivity can not be facilitated, it is recommended to disable NTP and solely rely on hypervisor time sync |
|
•
|
Enabled (Error: unable to communicate with daemon) will show in the unlikely case that the local NTP client is not running or reachable. Reapplying the settings (via Submit) may fix this, but if not, it is recommended to reach out to support. |
|
•
|
Enabled (Error: status check failed) will show in the unlikely case that an unknown error has occurred when attempting to query the status of the NTP client. It is recommended to reach out to support if this occurs. |
|
|
Appliance Time
|
This shows the current time from the appliance’s perspective. The displayed time will refresh approximately every 5 seconds.
