The vla-service connects to vCenter Server(s) to gather inventory and statistics. The service needs a vCenter Server SSO service account to log into vCenter Server. VMware recommends that you set up an account that has the least amount of privileges needed by the vla-Service. To create this account:
Create a VMware VLA role
If you are using VMware SSO, Create a VMware VLA user
Set the permission for the Appliance User
