I am using PowerShell to automate VM start/stop in Azure. However, when I set the $OPTION parameter it doesn't do anything. I have if/elseif/else statements.
See code below:
Add-AzureRmAccount -Credential $psCred -TenantId <removed> -ServicePrincipal
Get-AzureRmSubscription -SubscriptionName "<removed>"
#Get VMs using Tags
$vms = (Find-AzureRmResource | Where-Object {($_.tags.Project -eq "DevOps") -And ($_.tags.Test -eq "ernest")} | Select Name, ResourceGroupName)
$vms
Write-Output "Number of Virtual Machines: $($vms.Name.Count)"
foreach($VM in $vms)
{
if ($OPTION -eq "start" -And $VM.ResourceType -eq "Microsoft.Compute/virtualMachines")
{
Write-Output "Starting :- $VM.Name in $VM.ResourceGroupName"
Start-AzureRmVM -ResourceGroupName $VM.ResourceGroupName -Name $VM.Name -Verbose
Write-Output $VM.Name "has started successfully"
Write-Output "Writing output to workspace"
Get-AzureRmVM -Status | Where-Object {($_.tags.Project -eq "DevOps") -And ($_.tags.Test -eq "ernest")} | Select Name, ResourceGroupName, PowerState > VM_Start_Info-$(get-date -f yyyy-MM-dd).tsv
}
elseif ($OPTION -eq "stop" -And $VM.ResourceType -eq "Microsoft.Compute/virtualMachines")
{
Write-Output "Deallocating :- $VM.Name in $VM.ResourceGroupName"
Stop-AzureRmVM -ResourceGroupName $VM.ResourceGroupName -Name $VM.Name -Force -Verbose
Write-Output $VM.Name "has been deallocated successfully"
Write-Output "Writing output to workspace"
Get-AzureRmVM -Status | Where-Object {($_.tags.Project -eq "DevOps") -And ($_.tags.Test -eq "ernest")} | Select Name, ResourceGroupName, PowerState > VM_Stopped_Info-$(get-date -f yyyy-MM-dd).tsv
}
else
{
Write-Output "No option selected, select an option"
}
}
Write-Output "Script complete"
I had to add the $env:OPTION parameter to the Execute Powershell window. It works now

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"
}
}
}
My Powershell script is not explicitly calling for any specific resources but I am getting "ErrorCode: TargetResourceNotFound" error. I have attached the error in the image. What am I missing?
$subs = Get-AzSubscription | Where-Object {$_.Name -like "*-NonProd"}
foreach ($sub in $subs)
{
Select-AzSubscription -SubscriptionId $sub.Id
$RGs = Get-AzResourceGroup | Where-Object {$_.ResourceGroupName -like "*Infra"}
foreach ($RG in $RGs)
{
$NetworkWatchers = Get-AzNetworkWatcher
$NSGs = (Get-AzNetworkSecurityGroup).Id
foreach ($NSG in $NSGs)
{
foreach ($NetworkWatcher in $NetworkWatchers)
{
$Status = Get-AzNetworkWatcherFlowLogStatus -NetworkWatcherName $NetworkWatcher.Name
ResourceGroupName $RG.ResourceGroupName -TargetResourceId $NSG -Verbose
}
if (($Status).Enabled -eq $true)
{
Write-Output "$NSG in $(($sub).Name) has FlowLogs Enabled" | Tee-Object -FilePath 'C:\Users\user1\downloads\Output.txt' -Verbose -Append
}
if (($Status).Enabled -ne $true)
{
Write-Output "$NSG in $(($sub).Name) does not have FlowLogs Enabled" | Tee-Object -FilePath 'C:\Users\user1\downloads\Output.txt' -Verbose -Append
}
}
}
}
enter code here
Error Attached
Network Watchers are usually in a hidden resource group, and perhaps you are trying to find one in one of the available RGs. Try omitting the RG factor and use
$subs = Get-AzSubscription | Where-Object { $_.Name -like "*-NonProd" }
foreach ($sub in $subs) {
Select-AzSubscription -SubscriptionId $sub.Id
$NetworkWatchers = Get-AzNetworkWatcher
$NSGs = (Get-AzNetworkSecurityGroup).Id
foreach ($NSG in $NSGs) {
foreach ($NetworkWatcher in $NetworkWatchers) {
$Status = Get-AzNetworkWatcherFlowLogStatus -NetworkWatcher $NetworkWatcher -TargetResourceId $NSG -Verbose
}
if (($Status).Enabled -eq $true) {
Write-Output "$NSG in $(($sub).Name) has FlowLogs Enabled" | Tee-Object -FilePath 'C:\Users\user1\downloads\Output.txt' -Verbose -Append
}
if (($Status).Enabled -ne $true) {
Write-Output "$NSG in $(($sub).Name) does not have FlowLogs Enabled" | Tee-Object -FilePath 'C:\Users\user1\downloads\Output.txt' -Verbose -Append
}
}
}
I am able to get all flow logs configuration status.
Here is another approach:
I tried to reproduce the same in my environment and got the same error as below:
The error TargetResourceNotFound usually occurs if you are passing invalid resource group name or subscription name.
To confirm whether the resource group or subscription exists, execute the below code lines separately like below:
$subs = Get-AzSubscription | Where-Object {$_.Name -like "*-name"}
$subs
$RGs = Get-AzResourceGroup | Where-Object {$_.ResourceGroupName -like "*name"}
$RGs
The error states that Target resource identifier /subscriptions/subid/resourceGroups/RG/providers/Microsoft.Network/networkWatchers/*** not found in the region westeurope. Cross-verify whether the Network Watcher exists.
I am able to get the status of the Network Watcher successfully when I passed valid subscription and Resource group like below:
If the error still persists, try excluding the $RGs = Get-AzResourceGroup | Where-Object {$_.ResourceGroupName -like "*name"} and execute.
I appreciate your assistance.
I got it working by changing -NetworkWatcherName $NetworkWatcher.Name to -NetworkWatcherName $NetworkWatcher.ResourceGroupName
foreach ($NSG in $NSGs)
{
# $NSG.Id
# $NSGid = $NSG.Id
foreach ($NetworkWatcher in $NetworkWatchers)
{
$Status = Get-AzNetworkWatcherFlowLogStatus -NetworkWatcherName $NetworkWatcher.ResourceGroupName -ResourceGroupName $RG.ResourceGroupName -TargetResourceId $NSG -Verbose -ErrorAction SilentlyContinue
if (($Status).Enabled -eq $true)
{
Write-Output "$NSG in $(($sub).Name) has FlowLogs Enabled" | Tee-Object -FilePath 'C:\Users\A240379\downloads\OutEnabled.csv' -Verbose -Append
}
if (($Status).Enabled -ne $true)
{
Write-Output "$NSG in $(($sub).Name) does not have FlowLogs Enabled" | Tee-Object -FilePath 'C:\Users\A240379\downloads\OutNotEnabled.csv' -Verbose -Append

Context : I am automating starting of 3 Azure VM through a PowerShell script, and each VM is taking 4-5min to start. I want to run the start command parallel and after 5-6min verify them whether they are started.
function restartLoadAgents ($AzuresecretValue,$AzureApplicationID,$AzureObjectID,$AzureDirectoryID,$AzureUserName,$AzureSubscriptionID) {
$password = ConvertTo-SecureString $AzuresecretValue -AsPlainText -Force;

#List all the Load Agents
$VMList = Get-AzVm -ResourceGroupName $LoadAgentResourceGroup -Status;
ForEach($VM in $VMList) {
#Skipping the Master Machine and DB machine
if ($VM.Name -eq "test-load-appmachine01" -or $VM.Name -eq "test-load-appmachine02") {
continue;
}
$VMLoadAgentStatus = (Get-AzVm -ResourceGroupName $LoadAgentResourceGroup -Name $VM.Name -status).Statuses
$CurrentLoadAgentRunningStatus = $VMLoadAgentStatus[1].DisplayStatus;
if($CurrentLoadAgentRunningStatus -match "deallocated" -or $CurrentLoadAgentRunningStatus -match "VM deallocated"){

There are 5 VM in total and first two need not to be stopped or started. test-load-appmachine03,test-load-appmachine04 & test-load-appmachine05 are the target VM and I want to start them parallelly and check after.
I have a Powershell script that checks on a set of VM status before starting them. If the VM'S are in deallocating mode there should be a sleep and retry on 30 seconds. The code does not do a a retry. The code does a vm start in batches on 2 for vm's with wilcards as mentioned below in an order.
Need help if possible
$ResName= "resvmtest"
$action="start"
if($action -eq "start"){
$vnames=#('*dom*','*DBs*','*')
foreach($vname in $vnames) {
Write-Host "Starting VM with "$vname
$vmList = Get-AzVM -ResourceGroupName $ResName -Name $vname -Status | Select-Object Name, PowerState, ResourceGroupName
do{
$batch = #{
Skip = 0
First = 2
}
do{
foreach($vm in ($vmList | Select-Object #batch)){
$Stoploop = $false
[int]$Retrycount = "0"
do {
try {
if($vm.PowerState -eq "VM Deallocated"){
Write-Host "Job completed"
$Stoploop = $true
}
}
catch {
if ($vm.PowerState -eq "VM Deallocatting") {
Write-Host "VM Still not Deallocated"
Start-Sleep -Seconds 10
$Retrycount = $Retrycount + 1
}
}
}
While ($Stoploop -eq $false)
$params = #($vm.Name, $vm.ResourceGroupName,$vm.PowerState)
$job = Start-Job -ScriptBlock {
param($ComputerName,$serviceName,$statuses)
Start-AzVM -Name $ComputerName -ResourceGroupName $serviceName
} -ArgumentList $params
}
Wait-Job -Job $job
Get-Job | Receive-Job
$batch.Skip += 2
}
until($batch.skip -ge $vmList.count)
}
while($job.state -ne "Completed")
}
}
If you just want to wait for a VM's PowerState turns to VM Deallocated from VM Deallocatting, try the code below:
$vms = Get-AzVm -Status| Select-Object Name, PowerState,ResourceGroupName
#pick certain vm for demo here.
$vm = $vms[1]
$retryCount = 0
while($vm.PowerState -eq 'VM deallocating'){
Write-Host "waiting for VM deallocated..."
Start-Sleep -Seconds 5
$retryCount +=1
Write-Host "check count:$retryCount"
#get latest vm status
$vm.PowerState = (Get-AzVM -Name $vm.Name -ResourceGroupName $vm.ResourceGroupName -Status).Statuses[1].DisplayStatus
Write-Host "vm current state:"$vm.PowerState
}
Write-Host "vm new state:" + $vm.PowerState

I am trying to run the below powershell script
The below script is being used to list local users in a VM
$subscriptions=Get-AzSubscription -SubscriptionId "##################"
foreach ($subscription in $subscriptions){
Select-AzSubscription -SubscriptionId $subscription.SubscriptionId
$instances=Get-AzVM -Status | Select-Object Name,PowerState,ResourceGroupName ,#{l='osType';e={$\_.StorageProfile.osDisk.osType}}
foreach ($instance in $instances){
Write-Host $instance.Name.Name
Write-Host $instance.osType
if($instance.osType -eq "Windows"){
Write-Host "Windows server"
if($instance.PowerState -eq "VM running"){
$users=Invoke-AzVMRunCommand -ResourceGroupName $instance.ResourceGroupName -Name $instance.Name -CommandId 'RunPowerShellScript' -ScriptPath 'C:\Users\tushar.raichand\Desktop\sample.ps1'
Write-Host $users
Write-Host "####################################################"
foreach($user in $users){
Write-Host $user
}
}
}
else{
if($instance.PowerState -eq "running"){
Write-Host "Linux server"
}
}
}
}
Sample.ps1 is as below
$output = Get-LocalUser
Write-Output $output
$output
The output i am getting for Invoke-AzVMRunCommand is
Microsoft.Azure.Commands.Compute.Automation.Models.PSRunCommandResult
Where as when i just run this command in console
Invoke-AzVMRunCommand -ResourceGroupName $instance.ResourceGroupName -Name $instance.Name -CommandId 'RunPowerShellScript' -ScriptPath 'C:\Users\tushar.raichand\Desktop\sample.ps1'
I am getting the users list.
Well, I can reproduce your issue. The issue was caused by Write-Host $users, you need to change it to Write-Output $users.
Sample:
$users=Invoke-AzVMRunCommand -ResourceGroupName $instance.ResourceGroupName -Name $instance.Name -CommandId 'RunPowerShellScript' -ScriptPath 'C:\Users\joyw\Desktop\sample.ps1'
Write-Output $users
Besides, your script has some small mistakes, e={$\_.StorageProfile.osDisk.osType} should be e={$_.StorageProfile.osDisk.osType}. Write-Host $instance.Name.Name should be Write-Host $instance.Name, it is enough.
