    Note: The time different between servers will be unique to the time drift between the vROps nodes.

Cause

This issue occurs due to NTP time drift between the vRealize Operations Manager nodes.

Resolution

To resolve this issue, perform these steps:
  • Ensure all NTP servers configured for use with the vRealize Operations Manager nodes (Analytics and Remote Collector Clusters) are accessible.
  • Update the ntp.conf file (located in /etc/) with new NTP server(s) in each vRealize Operations Manager node if the original NTP servers are no longer available.
For more information, consult Configure NTP on VMware Appliances in the vRealize Operations Manager Help Guide.
