This is a known issue affecting VMware vSAN 6.5.x, 6.7.x and 7.0.x with NSX-T Data Center environment.
Currently, there is no resolution.
Workaround:
To work around this issue, get the metrics of the physical adapters using the PowerCLI command Get-VsanStats.
For example:
- Run the PowerCLI command:
Get-VsanStat -Entity $pnics[0] -StartTime $startTime -EndTime $endTime
- vsantop application: please log in the host which you want to monitor the metrics of the physical adapter and run the command "/bin/vsantop", and press button 'E' to choose the entity type "vsan-pnic-net".
