As I explained in the previous post, Azure allows the provisioning of extensions to cloud-hosted VMs through a VM Agent.
If you have ever gone through a large deployment of extensions to existing Azure VMs, via the Set-AzureVMDscExtension cmdlet, you have probably sought a way to check for the deployment status in a simpler manner then browsing into each and every VM in the Azure Portal:
Here's how PowerShell answers this need, and it does it in just one line of code. The core cmdlet here is Get-AzureRmVM, which is generally used to report VM status:
Get-AzureRmVM -WarningAction SilentlyContinue ResourceGroupName Name Location VmSize OsType NIC ProvisioningState ----------------- ---- -------- ------ ------ --- ----------------- RG-AD adVM westeurope Standard_D2_v2 Windows adNic Succeeded RG-AppServices VM0 westeurope Standard_A1 Windows nic0 Succeeded RG-AppServices VM1 westeurope Standard_A1 Windows nic1 Succeeded RG-DSC VM2012 westeurope Standard_A1 Windows vm2012373 Succeeded RG-DSC VM2016 westeurope Standard_A1 Windows vm2016964 SucceededAs a side information, I am settings the WarningAction parameter to SilentlyContinue simply because I don't want the following warning message to make my output less readable:
WARNING: Breaking change notice: In upcoming releaese, top level properties, DataDiskNames and NetworkInterfaceIDs, will be removed from VM object because they are also in StorageProfile and NetworkProfile, respectively.
I know very well that releases of Azure cmdlet are coming at a fast pace, so I can suppress this message.
Here's the oneliner I wrote:
Get-AzureRmVM -WarningAction SilentlyContinue | % {
(Get-AzureRmVM -ResourceGroupName $_.ResourceGroupName -name $_.name -status -OutVariable x -WarningAction SilentlyContinue).extensions | % {
$_ | select @{Name="VmName";Expression={$x.name}},@{Name="Extension";Expression={$_.name}},@{Name="Level";Expression={$_.statuses.level}},@{Name="Status";Expression={$_.statuses.displaystatus}},@{Name="Time";Expression={$_.statuses.time}}
}
}
The output can be piped to Format-Table if I want a table view, or to Out-Gridview, if you prefer:
Get-AzureRmVM -WarningAction SilentlyContinue | % {
(Get-AzureRmVM -ResourceGroupName $_.ResourceGroupName -name $_.name -status -OutVariable x -WarningAction SilentlyContinue).extensions | % {
$_ | select @{Name="VmName";Expression={$x.name}},@{Name="Extension";Expression={$_.name}},@{Name="Level";Expression={$_.statuses.level}},@{Name="Status";Expression={$_.statuses.displaystatus}},@{Name="Time";Expression={$_.statuses.time}}
}
} | Format-Table * -Autosize

I could also think of showing just the failures:Get-AzureRmVM -WarningAction SilentlyContinue | % {
(Get-AzureRmVM -ResourceGroupName $_.ResourceGroupName -name $_.name -status -OutVariable x -WarningAction SilentlyContinue).extensions | % {
$_ | select @{Name="VmName";Expression={$x.name}},@{Name="Extension";Expression={$_.name}},@{Name="Level";Expression={$_.statuses.level}},@{Name="Status";Expression={$_.statuses.displaystatus}},@{Name="Time";Expression={$_.statuses.time}}
}
} | ? Status -match 'Failed'
VmName : VM2012
Extension : DSC
Level : Error
Status : Provisioning failed
Time : 6/29/2017 2:35:39 PM
As I can see in the last output, the DSC extension failed to deploy on one of my Azure VMs, and I need to take corrective actions. I will discuss in a future post how to automatically solve this kind of issues staying on the same line of code.
