Issue/Introduction

  • When executing a "VALIDATE CONNECTION" action on a adapter instance in Aria Operations it times out and fails with the info message:

    ControllerInterface.getCollectorsHeartbeats failed...


  • When accessing UI objects such as a menu item in the Aria Operations UI it times out.
  • When running the date command on the Aria Operations nodes you observe there is a time difference compared to the current time.
  • In the /var/log/ntp log file contain the below messages:

    kernel reports TIME_ERROR: 0x41: Clock Unsynchronized


  • If /var/log/ntp log file contain the below log messages it indicates the NTP server is not configured. Please see Configure NTP on Aria Operations Appliances.

    ntpd[9764]: no reply; clock not set
    ntpd[9798]: ntpd exiting on signal 15

  • There is a value greater than 3.0> listed in the /var/lib/ntp/drift/ntp.drift file.

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
