Upgrade Veeam ONE to version 11 or later.
Starting with Veeam ONE v11, a new collection method was implemented to prevent this issue.
The following registry value can be used to force Veeam ONE v10 or v10A to use an alternate vSAN data collection method to mitigate vSAN impact.
Create the following registry value on the Veeam ONE server.
Key Location: HKLM\SOFTWARE\Veeam\Veeam ONE Monitor\Service\
Value Name: VsanLowLevelApi
Value Type: DWORD (32-Bit) Value
Value Data: 0
Restart the Veeam ONE services afterward.
