Time synchronization is important for the operation 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.

Table 1. Design Decision on Time Synchronization in vRealize Log Insight
Decision ID Design Decision Design Justification Design Implication
CSDDC-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. All applications must synchronize time to the same NTP time source.
