hostd.log (A) and vpxd.log (B) are key logs for ESXi and vCenter, and forwarding logs to vRealize Log Insight (D) centralizes analysis. Ephemeral port bindings (C) are unrelated to logging practices.

This allows the library to be accessible by other vCenter instances, where they can subscribe to it, ensuring the content is shared.

NIOC (A) can prioritize critical traffic, VMXNET3 (B) is VMware's optimized virtual NIC, and consistent Jumbo Frame configuration (D) prevents fragmentation. Isolating vCenter (C) may help security but doesn't inherently improve latency for production VMs.
