Create a Script-Based Custom Property for a vSphere Object

You can create a custom property by writing a script and providing a name for the property. The script evaluates when the custom property is called for the first time.

Prerequisites

Verify that you are connected to a vCenter Server system.

Procedure

```
New-VIProperty -Name NameOfHost -ObjectType VirtualMachine -Value { return $args[0].VMHost.Name }
```
View the NameOfHost properties of the available virtual machines.
```
Get-VM | select Name, NameOfHost | Format-Table -AutoSize
```

Results

You created a custom script property named NameOfHost for VirtualMachine objects.
