Time synchronization is critical for the core functionality of vRealize Log Insight. By default, vRealize Log Insight synchronizes time with a pre-defined list of public NTP servers.

NTP Configuration

Configure consistent NTP sources on all systems that send log data (vCenter Server, ESXi, vRealize Operation Manager). See Time Synchronization in the VMware Validated Design Planning and Preparation documentation.

Design Justification

Design Implication

SDDC-OPS-LOG-029

Configure consistent NTP sources on all virtual infrastructure and cloud management applications for correct log analysis in vRealize Log Insight.

Guarantees accurate log timestamps.

Requires that all applications synchronize time to the same NTP time source.
