To ensure that the vSAN adapter can collect all performance data, the Virtual SAN performance service must be enabled in vSphere. For instructions on how to enable the service, see Turn on Virtual SAN Performance Service in the VMware Virtual SAN documentation.

If the Virtual SAN performance service is disabled or experiencing issues, an alert is triggered for the vSAN adapter instance and the following errors appear in the adapter logs.

ERROR com.vmware.adapter3.vsan.metricloader.VsanDiskgroupMetricLoader.collectMetrics 
   - Failed to collect performance metrics for Disk Group
