协助循环浏览多个订阅

Question

我正在使用http://vcloud-lab.com/entries/microsoft-azure/get-azure-virtual-machine-backup-reports-using-powershell中的以下脚本来获取Azure备份详细信息。目前，我必须对每个订阅运行脚本，我希望让它循环通过所有订阅。

我一直在尝试使用这个例子https://www.jpaul.me/2019/05/azure-automation-how-to-quickly-work-with-many-subscriptions/让它正常工作，但是我对powershell还不熟悉，而且还在挣扎。如有任何建议，我们将不胜感激。

    .SYNOPSIS
    Collect Azure VM Backup Information

    .DESCRIPTION
    This Script collects Azure Virtual Machine Backup Recovery service vault information, This report includes the complete backup status Information of VM.

    .PARAMETER AllVirtualMachines
    Collect Backup information of the all Azure Virtual Machines, This is default parameter.

    .PARAMETER VirtualMachineList
    You can specify for which virtual machine you want backup information.

    .INPUTS
    None. Provides virtual machine information.

    .OUTPUTS
    Generate Backup information. You can pipe information to Export-CSV.

    .EXAMPLE
    PS> .\Get-AzVMBackupInformation.ps1
    
    VM_Name                         : vcloud-lab-vm01
    VM_Location                     : uksouth
    VM_ResourceGroupName            : VCLOUD-LAB.COM
    VM_BackedUp                     : True
    VM_RecoveryVaultName            : vault828
    VM_RecoveryVaultPolicy          : DailyPolicy-kosrnox0
    VM_BackupHealthStatus           : Passed
    VM_BackupProtectionStatus       : Healthy
    VM_LastBackupStatus             : Completed
    VM_LastBackupTime               : 27-05-2021 19:32:34
    VM_BackupDeleteState            : NotDeleted
    VM_BackupLatestRecoveryPoint    : 27-05-2021 19:32:37
    VM_Id                           : /subscriptions/9e22xxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourceGroups/VCLOUD-LAB.COM/providers/Microsoft.Compute/virtualMachines/vcloud-lab-vm01
    RecoveryVault_ResourceGroupName : vCloud-lab.com
    RecoveryVault_Location          : uksouth
    RecoveryVault_SubscriptionId    : /subscriptions/9e22xxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourceGroups/vCloud-lab.com/providers/Microsoft.RecoveryServices/vaults/vault828

    .EXAMPLE
    PS> .\Get-AzVMBackupInformation.ps1 -AllVirtualMachines
    This produces same result as .\Get-AzVMBackupInformation.ps1 from all VMs

    .EXAMPLE
    PS> .\Get-AzVMBackupInformation.ps1 -VirtualMachineList
    Provide either single virtual machine name or in list

您可以从MS尝试这个示例脚本来循环多个订阅。

Connect-AzAccount

$SubscriptionList = Get-AzSubscription

foreach ($Id in $SubscriptionList)
{
    #Provide the subscription Id where the VMs reside
    $subscriptionId = $Id

    #Provide the name of the csv file to be exported
    $reportName = "myReport.csv"
    Select-AzSubscription $subscriptionId
    $report = @()
    $vms = Get-AzVM
    $publicIps = Get-AzPublicIpAddress
    $nics = Get-AzNetworkInterface | ?{ $_.VirtualMachine -NE $null}

    foreach ($nic in $nics) 
        {
        $info = "" | Select VmName, ResourceGroupName, Region, VmSize, VirtualNetwork, Subnet, PrivateIpAddress, OsType, PublicIPAddress, NicName, ApplicationSecurityGroup, subscriptionId
        $vm = $vms | ? -Property Id -eq $nic.VirtualMachine.id

        foreach($publicIp in $publicIps) 
        {
            if($nic.IpConfigurations.id -eq $publicIp.ipconfiguration.Id) 
                {
                    $info.PublicIPAddress = $publicIp.ipaddress
                }
        }
        $info.subscriptionId = $subscriptionId
        $info.OsType = $vm.StorageProfile.OsDisk.OsType
        $info.VMName = $vm.Name
        $info.ResourceGroupName = $vm.ResourceGroupName
        $info.Region = $vm.Location
        $info.VmSize = $vm.HardwareProfile.VmSize
        $info.VirtualNetwork = $nic.IpConfigurations.subnet.Id.Split("/")[-3]
        $info.Subnet = $nic.IpConfigurations.subnet.Id.Split("/")[-1]
        $info.PrivateIpAddress = $nic.IpConfigurations.PrivateIpAddress
        $info.NicName = $nic.Name
        $info.ApplicationSecurityGroup = $nic.IpConfigurations.ApplicationSecurityGroups.Id
        $report+=$info
        }
    $report | ft subscriptionId, VmName, ResourceGroupName, Region, VmSize, VirtualNetwork, Subnet, PrivateIpAddress, OsType, PublicIPAddress, NicName, ApplicationSecurityGroup
    $report | Export-CSV "$home/$reportName"
}
