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 Decision

Design Justification

Design Implication


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

Guarantees accurate log timestamps.

All applications must synchronize time to the same NTP time source.
