Environment

Aria Operations 8.x
vRealize Operations 8.x

Cause

The Aria Operations nodes are experiencing a time drift from the configured NTP server. If the time drift exceeds 3000 milliseconds (3 seconds) the UI and adapter connections will start to time out.

Resolution

1. Verify the NTP server is configured and accessible from each Aria Operations node by reviewing /etc/ntp.conf 
   1. Verify the NTP IP or FQDN is listed under the ## CaSA Section Start # Added by CaSA
   2. Ping the NTP server via the configured IP or FQDN.
2. Stop the NTP daemon service:
   

   systemctl stop ntpd

3. Sync the time with the time server:
   

   ntpdate -u <NTP_Server-IPorFQDN>

4. Start the NTP daemon service:
   

   systemctl start ntpd

5. Verify the time is current via the date command:
   

   date
