Get Azure VM details by filtering using tags in powershell - azure

I will like to use the Get-AzVm command to get list of VMs having a specific tag.
I have tried Get-AzVM | Where-Object {$_.Tags['Resource'] -eq "test"}
Still does not return VMS with the tag "Resource:test"

The output of get-azvm doesn't produce Tags for VM. But, Get-AzVM -ResourceGroupName ResourceGroupName -Name VMName does that.
So you need to loop through VMs, store the VM tag in a hashtable and then enumerate through the hastable to check your desired tag with value is there. Here goes the code-
$VMs = get-azvm
foreach ($VM in $VMs)
{
[Hashtable]$VMTag = (Get-AzVM -ResourceGroupName $VM.ResourceGroupName -Name $VM.Name).Tags
foreach ($h in $VMTag.GetEnumerator()) {
if (($h.Name -eq "Resource") -and ($h.value -eq "test"))
{
Write-host "VM with tags Resource:test are" $VM.Name
}
}
}

Azure: Get resource for azure automation

I have runbook in Azure that i want to use in different RG,
My code
$vms = Get-AzVM -ResourceGroupName RG-TEST
foreach($vm in $vms)
{
$statuscheck = Get-AzVM -ResourceGroupName RG-TEST -Name $vm.Name -Status
if($statuscheck.Statuses.DisplayStatus[1] -eq "VM running")
{
Write-Output "Stopping virtual machine...$($vm.Name)"
Stop-AzVM -ResourceGroupName $vm.ResourceGroupName -Name $vm.Name -Force
}
else
{
Write-output "Virtual machine $($vm.Name) is already in stopped state"
}
}
How can I update the code that the script will get the name of the RG where it's located,
So that the RG is not hard coded
Dont know how to do it
Do something like this
$rgs = $(Get-AzVM)
# Get Distinct RG Names
$rgs = $rgs | Select-Object -Property ResourceGroupName | Sort-Object -Unique
foreach($rg in $rgs){
$vms = Get-AzVM -ResourceGroupName $rg.ResourceGroupName
foreach($vm in $vms)
{
$statuscheck = Get-AzVM -ResourceGroupName $rg.ResourceGroupName -Name $vm.Name -Status
if($statuscheck.Statuses.DisplayStatus[1] -eq "VM running")
{
Write-Output "Stopping virtual machine...$($vm.Name)"
Stop-AzVM -ResourceGroupName $rg.ResourceGroupName -Name $vm.Name -Force
}
else
{
Write-output "Virtual machine $($vm.Name) is already in stopped state"
}
}
}

How delete VM Azure using tags using powershell?

How do I delete a VM using tags? Let's say there is a VM with the tags "Name:Surname". How can I delete this VM without using the VM name or ID. Namely deletion using tags.
I try to use:
get-azvm -ResourceGroupName "ResourceGroup" | Where-Object {$_.Tags -like "[Name, blabla], [Surname, blabla]"}
but it didn't find that VM
I have reproduced in my environment. Firstly, you need to find the Virtual Machine using the below command:
xx- Name of the resource group
hello- tag name
get-azvm -ResourceGroupName "xx" | Where-Object {$_.Tags['hello']}
After getting the VM name you can use the below command to delete the VM:
xx- Name of the resource group
yy- Name of the vm.
Remove-AzVM -ResourceGroupName "xx" -Name "yy"
Then type Y(yes) to delete the VM as below:

https://learn.microsoft.com/en-us/powershell/module/az.compute/get-azvm?view=azps-8.2.0
Based on this,
You could do something like this:
$Surname= 'Test'
$VMs = Get-AzVM -ResourceGroupName 'myRG'
foreach ($VM in $VMs)
{
[Hashtable]$VMTag = (Get-AzVM -ResourceGroupName $VM.ResourceGroupName -Name $VM.Name).Tags
foreach ($h in $VMTag.GetEnumerator()) {
if (($h.Name -eq "Name") -and ($h.value -eq $Surname))
{
Write-host "Removing VM" $VM.Name
Remove-AzVM -ResourceGroupName $VM.ResourceGroupName -Name $VM.Name -Force -Confirm:$false
}
}
}

How to get the list of azure servers having Auto-Shutdown disabled using PowerShell?

I want to get the list of azure servers having auto-shutdown disabled on them, I have the below script but the issue with the script is that it gets the list of RG's under the Subscription GUID but repeats the output after every loop.
Import-AzureRmContext -Path "$PSScriptRoot\AzureProfile.json"
Select-AzureRmSubscription -SubscriptionId {subscriptionId}
[array]$ResourceGroupArray = Get-AzureRMVm | Select-Object -Property ResourceGroupName, Name, VmId
foreach ($resourceGroup in $ResourceGroupArray){
$targetResourceId = (Get-AzureRmVM -ResourceGroupName $resourcegroup.ResourceGroupName -Name $resourceGroup.Name).Id
$shutdownInformation = (Get-AzureRmResource -ResourceGroupName $resourcegroup.ResourceGroupName -ResourceType Microsoft.DevTestLab/schedules -Expandproperties).Properties
Write-Host "ID: " $targetResourceId
$shutdownInformation
The output for each VM is displayed in the following format,
What I want is simple, I want the VM name and its status of Auto-shutdown to be displayed on the screen so that its easy for me to find out which all VM have auto-shutdown currently disabled on them.
Any help related to this would be helpful.
You just need to get the microsoft.devtestlab/schedules resource ID using:
/subscriptions/{subscriptionId}/resourceGroups/{rgName}/providers/microsoft.devtestlab/schedules/shutdown-computevm-{vmName}
Then iterate over all your VMs using Get-AzVM, Get the microsoft.devtestlab/schedules resource using Get-AzResource, then output VM name and status into a table using Format-Table.
$subscriptionId = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
Set-AzContext -SubscriptionId $subscriptionId
& {
foreach ($vm in Get-AzVM) {
try {
$shutdownResource = Get-AzResource `
-ResourceId "/subscriptions/$subscriptionId/resourceGroups/$($vm.ResourceGroupName)/providers/microsoft.devtestlab/schedules/shutdown-computevm-$($vm.Name)" `
-ErrorAction Stop
[PSCustomObject]#{
VMName = $vm.Name
ShutdownStatus = $shutdownResource.Properties.status
}
}
catch {
[PSCustomObject]#{
VMName = $vm.Name
ShutdownStatus = $_.Exception.Message
}
}
}
} | Format-Table -AutoSize
To set the context to the correct subscription, we can use Set-AzContext.
The above however is using the latest Az modules. You can do the same using the equivalent AzureRm modules.
$subscriptionId = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
Set-AzureRmContext -SubscriptionId $subscriptionId
& {
foreach ($vm in Get-AzureRmVM) {
try {
$shutdownResource = Get-AzureRmResource `
-ResourceId "/subscriptions/$subscriptionId/resourceGroups/$($vm.ResourceGroupName)/providers/microsoft.devtestlab/schedules/shutdown-computevm-$($vm.Name)" `
-ErrorAction Stop
[PSCustomObject]#{
VMName = $vm.Name
ShutdownStatus = $shutdownResource.Properties.status
}
}
catch {
[PSCustomObject]#{
VMName = $vm.Name
ShutdownStatus = $_.Exception.Message
}
}
}
} | Format-Table -AutoSize
Although I do recommend moving to the Az module since support for AzureRm is ending December 2020. You can read the documentation for more information about this.
The above code should give you an output similar to the following
VMName ShutdownStatus
------ --------------
vm1 Enabled
vm2 Disabled
Update
The Call operator & is used here to run the for loop as a script block. You can read more about this in about_Script_Blocks.
Try something like this to get the auto-shutdown status of all VMs. Instead of trying to get the schedules inside the loop, get all the ones in the subscription and match them based on the VM's full resource Id.
[array]$VMArray = Get-AzureRMVm | Select-Object -Property ResourceGroupName, Name, VmId, Id
$ShutdownInformation = (Get-AzureRmResource -ResourceType Microsoft.DevTestLab/schedules -Expandproperties).Properties
foreach($vm in $VMArray) {
$ShutdownStatus = "Not Configured"
$Schedule = $ShutdownInformation | Where-Object { $_.targetResourceId -eq $vm.Id } | Select -First 1
if($Schedule -ne $null) {
$ShutdownStatus = $Schedule.status
}
Write-Host $vm.VmId $ShutdownStatus
}

Azure Automation Runbook missing mandatory parameters

I'm trying to set a Tag on all virtual machines in my subscription but I keep getting errors when running the Runbook.
The error is the following:
Get-AzureRmVM : Cannot process command because of one or more missing mandatory parameters: ResourceGroupName. At line:30
Here is my Runbook:
$azureConnection = Get-AutomationConnection -Name 'AzureRunAsConnection'

}
$null = Add-AzureRmAccount #params
}

Throw "Unable to authenticate with error: $errorMessage"
}

}
}
Write-Host "All tagging is done"
I tried importing the right modules but this doesn't seem to affect the outcome.
Running the same commands in Cloud Shell does work correctly.
I can reproduce your issue, the error was caused by this part Get-AzureRmVM -Name $azurevm, when running this command, the -ResourceGroupName is needed.
You need to use the Az command Get-AzVM -Name $azurevm, it will work.
Running the same commands in Cloud Shell does work correctly.
In Cloud shell, azure essentially uses the new Az module to run your command, you can understand it runs the Enable-AzureRmAlias before the command, you could check that via debug mode.
Get-AzureRmVM -Name joyWindowsVM -debug
To solve your issue completely, I recommend you to use the new Az module, because the AzureRM module was deprecated and will not be updated.
Please follow the steps below.
1.Navigate to your automation account in the portal -> Modules, check if you have imported the modules Az.Accounts, Az.Compute, Az.Resources, if not, go to Browse Gallery -> search and import them.
2.After import successfully, change your script to the one like below, then it should work fine.
$azureConnection = Get-AutomationConnection -Name 'AzureRunAsConnection'
#Authenticate
try {
Clear-Variable -Name params -Force -ErrorAction Ignore
$params = #{
ServicePrincipal = $true
Tenant = $azureConnection.TenantID
ApplicationId = $azureConnection.ApplicationID
CertificateThumbprint = $azureConnection.CertificateThumbprint
}
$null = Connect-AzAccount #params
}
catch {
$errorMessage = $_
Throw "Unable to authenticate with error: $errorMessage"
}
# Discovery of all Azure VM's in the current subscription.
$azurevms = Get-AzVM | Select-Object -ExpandProperty Name
Write-Host "Discovering Azure VM's in the following subscription $SubscriptionID Please hold...."
Write-Host "The following VM's have been discovered in subscription $SubscriptionID"
$azurevms
foreach ($azurevm in $azurevms) {
Write-Host "Checking for tag $vmtagname on $azurevm"
$tagRGname = Get-AzVM -Name $azurevm | Select-Object -ExpandProperty ResourceGroupName
$tags = (Get-AzResource -ResourceGroupName $tagRGname -Name $azurevm).Tags
If ($tags.UpdateWindow){
Write-Host "$azurevm already has the tag $vmtagname."
}
else
{
Write-Host "Creating Tag $vmtagname and Value $tagvalue for $azurevm"
$tags.Add($vmtagname,$tagvalue)
Set-AzResource -ResourceGroupName $tagRGname -ResourceName $azurevm -ResourceType Microsoft.Compute/virtualMachines -Tag $tags -Force `
}
}
Write-Host "All tagging is done"

Problem with PSCustomObject data collection

I'm preparing a table with information about VM name and provision date of OS disk. I can easily retrieve that information from $VM.disks.statuses.time[0] command, if individual VM is assigned to $VM, but I when i try to collect data into table, I got an error:
Cannot index into a null array.
At line:4 char:1
+ [PSCustomObject]#{
+ ~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (:) [], RuntimeException
+ FullyQualifiedErrorId : NullArray
This is my code:
$VMs = Get-AzVM -status
$vmOutput = $VMs | ForEach-Object {
[PSCustomObject]#{
"VM Name" = $_.Name
"Provision Date" = $_.disks.statuses.time[0].ToString()
}
}
I can reproduce your issue, the issue was caused by the outputs of Get-AzVM -status and Get-AzVM -ResourceGroupName <ResourceGroupName> -Name <Name> -Status are different.
The output of Get-AzVM -status will not has the disks property, but when you get individual VM status via Get-AzVM -ResourceGroupName <ResourceGroupName> -Name <Name> -Status, it will have the property, so you got the error.
Get-AzVM -status:
Get-AzVM -ResourceGroupName <ResourceGroupName> -Name <Name> -Status:
Solution:
To fix the issue, just to use Get-AzVM -ResourceGroupName <ResourceGroupName> -Name <Name> -Status in your script.
$VMs = Get-AzVM -status
$vmOutput = $VMs | ForEach-Object {
$VMstatus = Get-AzVM -ResourceGroupName $_.ResourceGroupName -Name $_.Name -Status
[PSCustomObject]#{
"VM Name" = $VMstatus.Name
"Provision Date" = $VMstatus.disks.statuses.time[0].ToString()
}
}
You can use the Get-AzDisk command to retrieve disk creation information.
$disks = Get-AzDisk | Where-Object { $_.Managedby }
$vmOutput = foreach ($disk in $disks) {
[pscustomobject]#{"VM Name" = ($disk.ManagedBy -split "/")[-1]
"Provisioned Date" = $disk.TimeCreated
}
}
The error says:
Cannot index into a null array.
So my guess is that something here $_.disks.statuses.time[0].ToString() is $null. Therefore you should add some $nullchecks:
$VMs = Get-AzVM -status
$vmOutput = $VMs | ForEach-Object {
if ($_.disks -and $_.disks.statuses -and $_.disks.statuses.time -and ($_.disks.statuses.time.Count -gt 0)){
[PSCustomObject]#{
"VM Name" = $_.Name
"Provision Date" = $_.disks.statuses.time[0].ToString()
}
}
}
Hope that helps.
