One or more clocks in a vIDM cluster show a warning in the System Diagnostics Dashboard

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

- vIDM 3 node Cluster. 

- Host time is configured for all nodes rather than an NTP server. 

- Clocks show a significant lag time and a yellow warning status. 

Environment

vIDM 3.3.7

Cause

This issue can be caused if "periodic updates for time sync" is disabled for one or more nodes in the VMware Tools settings for the affected Virtual Machines. 

Resolution

In the vSphere UI Right-click the Virtual Machine, select Edit Settings > VM Options tab > expand VMware Tools and check the Time Synchronization settings. 

If "periodic updates for time sync" is disabled you can enable it by checking the box. 

Additional Information

If "periodic updates for time sync" is disabled then VMware Tools only syncs time at power on, resume from snapshot or vMotion so time drift will be expected.
