Issue/Introduction
Design Decision: Communicate with the syslog clients, such as ESXi, vCenter Server, NSX-T Data Center, using the TCP protocol.
Resolution
Design Justification: Using the TCP syslog protocol ensures reliability and supports retry mechanisms.
TCP syslog traffic is secure and more consistent with RFC 5424.
Design Implication:
- TCP has a higher performance overhead compared to UDP.
- You must manually disable the SSL connection requirement in vRealize Log Insight.
This design decision is supported in the following Domains.
• Management Domain
• VI Workload Domain
This design decision is supported on VCF version 4.1 and higher.
