This alarm is generated when the system detects that the Network Time Protocol (NTP) service on the Computing Node Agent (CNA) cannot run properly, or the network connection between the CNA and the NTP server fails.
This alarm is cleared when both the NTP service on the CNA and the network connection between the CNA and the NTP server become normal.
The possible causes of this alarm are as follows:
•The NTP service on the CNA node is not running properly.
•The network connection between the CNA node and the external NTP server is abnormal.
•The time difference between the CNA node and the external NTP server exceeds 1 minute.
•The CNA node is configured with multiple external NTP server, and the time difference among these external NTP servers exceeds 50 milliseconds.
•The NTP server fails to provide time synchronization services
