Extracting several parameters from a VM from Azure through CLI (Code not working)

I’m trying to gather information about VMs through the CLI in order to get those faster than through the Azure-Portal.
I’m trying to extract the vnet, the subnet and the routing table for the given VM.
But this is my first time using the CLI and my code is not working. I have disabled the login/logout for now and the input of the VM name.

The error occurs at the line $vnetId = (Get-AzNetworkInterface -Name $vm.Name -ResourceGroupName $vm.ResourceGroupName).IpConfigurations[0].Subnet.Id.Split("/")[-3]

I’m getting the following error message: "

Get-AzNetworkInterface : The Resource ‘Microsoft.Network/networkInterfaces/vmva2015’ under resource group ‘RG-REDISPATCHPROD-PROD-001’ was not found. For more details please go to
https://aka.ms/ARMResourceNotFoundFix
StatusCode: 404
ReasonPhrase: Not Found
ErrorCode: ResourceNotFound
"

I’m fairly out of my depth and looking for help.

    Set-AzContext $subscription

    # Suchen der VM mit dem angegebenen Namen

        $subnet = Get-AzVirtualNetworkSubnet -Name $subnetId -VirtualNetwork $vnet
        $rtName = $subnet.RouteTable.Id.Split("/")[-1]
        $rt = Get-AzRouteTable -Name $rtName -ResourceGroupName $resourceGroupName

        # Ergebnisse ausgeben

        Write-Host "Name des Subnet: $($subnet.Name)"
        Write-Host "Name der Routing-Tabelle: $($rt.Name)"

        # Das Skript endet, sobald eine VM gefunden wurde
        break
    }
}

Best,

I have tried several internet searches which lead me to different site, but my knowledge is too limited to find an answer (and I have tried for roughly 6–7 hours by now).

    Extracting several parameters from a VM from Azure through CLI (Code not working)

    I have used below PowerShell code to retrieve the VM properties (VM Name, VNet, Subnet, NIC & Route Table)

    VM Property details in portal

    enter image description here

    I have followed this MS Document1 & MS Document2 & MS Document3 as a reference to extracting several parameters from a VM.

    PowerShell Code

        $vmName = "VM8"
    $subscriptions = Get-AzSubscription
    foreach ($subscription in $subscriptions) {
        Set-AzContext $subscription
        $vm = Get-AzVM -Name $vmName -ErrorAction SilentlyContinue
        $resourceGroupName = $vm.ResourceGroupName
        if ($vm) {
            $networkInterface = Get-AzNetworkInterface -ResourceId $vm.NetworkProfile.NetworkInterfaces[0].Id
            $ipConfig = $networkInterface.IpConfigurations[0]
            $subnet= (Get-AzNetworkInterface -Name $ipConfig.Name -ResourceGroupName $resourceGroupName).IpConfigurations.Subnet.Id.Split("/")[-1]
            $virtualNetwork= (Get-AzNetworkInterface -Name $ipConfig.Name -ResourceGroupName
$resourceGroupName).IpConfigurations.Subnet.Id.Split("/")[-3]
            $routeTable= (Get-AzVirtualNetwork -ResourceGroupName $resourceGroupName -Name $virtualNetwork).Subnets
            $routeTableId = $routeTable.RouteTable.Id
            $routeTableName = $routeTableId.Split("/")[-1]
            Write-Output "Virtual Machine Name: $($vm.Name)"
            Write-Output "Virtual Network Name: $virtualNetwork"
            Write-Output "Network Interface Name: $($networkInterface.Name)"
            Write-Output "Subnet Name: $subnet"
            Write-Output "Route Table Name: $routeTableName"
        }
    }

    Output

    Have you tried this command line?

    az network vnet show -g MyResourceGroup -n MyVNet && az network route-table show -g MyResourceGroup -n MyRouteTable

    It will show you all the details you need.

    If you need more information, just follow this link:
