Azure VM - OS build number RRS feed

  • Question

  • Hello Everyone,

    I would like to loop through all the VM's and find the OS build number. I found ways post logging into the VM like msinfo32, [System.Environment]::OSversion etc but none on the lines of remotely getting the info using powershell.

    With the limited knowledge I created the below script but I am not getting the OSbuild number :(

    param(
        # Specify the location of the audit file
        $csvFilePath = "C:\agentAudit.csv"
    )
    cls
    
    $ErrorActionPreference = 'Stop'
    Write-Host "Validating Azure Accounts..."
    try{
        $subscriptionList = Get-AzureRmSubscription | Sort SubscriptionName
    }
    catch {
        Write-Host "Reauthenticating..."
        Login-AzureRmAccount | Out-Null
        $subscriptionList = Get-AzureRmSubscription | Sort SubscriptionName
    }
    if (Test-Path $csvFilePath) {
        Remove-Item -Path $csvFilePath
    }
    foreach($subscription in $subscriptionList) {
        Select-AzureRmSubscription -SubscriptionId $subscription.SubscriptionId | Out-Null
        Write-Output "`n Working on subscription: $($subscription.SubscriptionName) `n"
        $vms = Get-AzureRmVM -WarningAction Ignore
        foreach ($vm in $vms) {
        $VMs = Get-AzureRmVM 
        $vmlist = @() 
        $VMs | ForEach-Object {  
            $VMObj = New-Object -TypeName PSObject 
            $VMObj | Add-Member -MemberType Noteproperty -Name "VM Name" -Value $_.Name 
            $VMObj | Add-Member -MemberType Noteproperty -Name "OS type" -Value $_.StorageProfile.ImageReference.Sku
            $VMObj | Add-Member -MemberType Noteproperty -Name "OS Offer" -Value $_.StorageProfile.ImageReference.Offer
            $VMObj | Add-Member -MemberType Noteproperty -Name "OS Publisher" -Value $_.StorageProfile.ImageReference.Publisher
            $VMObj | Add-Member -MemberType Noteproperty -Name "OS Version" -Value $_.StorageProfile.ImageReference.Version
        $vmlist += $VMObj 
    } 
    $vmlist  
    }
    }


    I would appreciate if anyone with PS scripting knowledge would be able to help me

  • Firewall?   Is the VM a non-Windows VM?

  • Its a windows VM and no additional firewall/security apart from the default present in the OS.

  • If it is not a part of the network you are running from you will need to use credentials.

    Note that all Windows Version numbers contain the buildnumber in the last digits.

    ([version]$version).Build

    or

    ([version]$_.StorageProfile.ImageReference.Version).Build

  • The version number you are using is not a version number and is not an OS version.  I didn't test it and did not expect it to be a non-standard version.

    You must use the WMI call to get the info.  You will have to troubleshoot the connections and firewall setting.

    You cannot use WMI across the Internet.  If you have remoting enabled and configured than use that.
