An administrator is responsible for monitoring VMware vSAN performance across a VMware Cloud Foundation (VCF)...

According to the VCF 9.0 Operations and vSAN Integration Guide, performance metrics in the vSAN Cluster Performance widget are only available when the vSAN Performance Service is enabled. The documentation states:

“The vSAN Performance Service must be enabled in vCenter Server for each vSAN cluster to collect and visualize performance statistics in VCF Operations. Without this service, performance dashboards and widgets will not display data.”

Option A (Support Insight) relates to telemetry with VMware, not performance widgets.

Option B (Cloud proxy as Collector) is required for general collection but not specific to vSAN widget visibility.

Option C (SMART data collection) provides disk health analytics, not cluster-level performance stats.

Option D is correct, because enabling the vSAN Performance Service ensures that VCF Operations receives and displays data in the vSAN Performance dashboards.

Therefore, the administrator must enable the vSAN Performance Service for all vSAN clusters in vCenter.
