Powershell 如何将VM标记添加到输出文本文件中

我正在获取VMWare环境中所有快照的列表，我正在格式化该列表以获取“VM、Name、Created、SizeGB”，我还希望从这些VM获取VMWare服务器标记信息，但我不确定如何执行此操作。我想获取标签信息，并在列表格式化时将其放在“SizeGB”下。有办法做到这一点吗

这是我的脚本，没有标签信息：

# Adding PowerCLI Snap-in to use cmdlets to connect to vSphere
Add-PSSnapin VMware.VimAutomation.Core

# Connect to vCenter
Connect-ViServer -server $vCenter -ErrorAction Stop 

# Write header on report
Write-Output "VMWare Snapshot Report for $(get-date -f MM-dd-yyyy)" |
    Out-File $Log -Append

# Get VM Snapshot Information for all Snapshots and send that information to
# c:\automation\AllSnapshots.txt
Get-VM | Get-Snapshot | Where-Object {
    $_.Created -lt (Get-Date).AddDays(-3)
} | Format-List vm, name, created, sizegb | Out-File $Log -Append

# Disconnect from vCenter
Disconnect-VIServer -Server * -Force -Confirm:$false

---

我尝试使用此命令，但没有输出到文件。如果使用remove-Out-File cmdlet，在控制台中是否看到任何输出？对于我来说，使用vCenter 5.5和PowerCLI 6.0很好。

    Out-File $Log -Append

$output = @()
foreach ($vm in Get-VM) {
   $tags = ((Get-TagAssignment -Entity $vm | select -ExpandProperty Tag).Name -join ", ")
   foreach ($snapshot in $vm | Get-Snapshot | Where-Object { $_.Created -lt (Get-Date).AddDays(-3) }) {
       $obj = [PSCustomObject]@{VM = $vm.Name; Name = $snapshot.Name; Created = $snapshot.Created; SizeGB = $snapshot.SizeGB; Tags = $tags}
       $output += $obj
   }
}
$output | Format-List | Out-File $Log -Append

# Disconnect from vCenter
Disconnect-VIServer -Server * -Force -Confirm:$false
