Symptoms

測試 NTP 伺服器時，如果能夠同步時間，則顯示伺服器已中斷。但是，再次運行該命令時，它顯示伺服器正在同步時間。

----------------------------------------------------------------------
WARNING - One or more NTP servers are NOT suitable for synchronization
----------------------------------------------------------------------
Node      = Nodes
Extra     = {"Nodes": ["169.254.1.1", "169.254.1.2", "169.254.1.3", "169.254.1.4"]}
Timestamp = 2025-11-21_151945
PSNT      = APM00xxxxxxxxx @ 4.8-106.1


1- 取得每個列出節點上的 NTP 伺服器清單：
命令：

# getrackinfo -r | grep NTP

範例：

admin@node1:~> getrackinfo -r | grep NTP
        NTPServer =  xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx

 

2-測試它是否能夠同步時間。 

命令：

# sudo ntpdate -p 2 -d <NTP IP Address / NTP FQDN>
or
# sudo ntpdate -p 2 -d `getrackinfo -r | grep NTP |grep -oP "(?:[0-9]{1,3}\.){3}[0-9]{1,3}"`

範例：

admin@node1:~> sudo ntpdate -p 2 -d 123.x.xx.xx
10 Mar 11:06:15 ntpdate[69998]: ntpdate 4.2.8p15@1.3728-o Thu Jun 25 14:17:29 UTC 2020 (1)
Looking for host 123.x.xx.xx and service ntp
123.x.xx.xx reversed to <NTP hostname>
host found : <NTP hostname>
transmit(123.x.xx.xx)
transmit(123.x.xx.xx)
123.x.xx.xx: Server dropped: no data

10 Mar 11:06:19 ntpdate[69998]: no server suitable for synchronization found


等待幾秒鐘，然後再次運行相同的命令：

admin@node1:~> sudo ntpdate -p 2 -d 123.x.xx.xx
10 Mar 11:06:24 ntpdate[70526]: ntpdate 4.2.8p15@1.3728-o Thu Jun 25 14:17:29 UTC 2020 (1)

Cause

NTP 伺服器對 NTP 請求有速率限制。
當 xDoctor 嘗試同時同步所有節點，而 NTP 伺服器有速率限制時，它只會回應第一個節點。
xDoctor 發送所有請求，它們之間沒有延遲，因此它們會被伺服器阻止。

Resolution

xDoctor 團隊已確認在未來的 xDoctor 版本中解決此問題。（目前版本：4.8-89.0）
請求資訊： 減少ntpdate 命令以避免 NTP 速率限制，當 xDoctor 未執行檢查時，NTP 速率限制會導致偽陽性。
