extension installation failure for azure windows vm through powershell script

Azure-learning 56

I am trying to install "microsoft monitoring " agent through powershell script in azure windows based vms.

I am getting error "This operation cannot be performed when extension operations are disallowed. To allow, please ensure VM Agent is installed on the VM and the
osProfile.allowExtensionOperations property is true".

Please suggest how to install the vmagent and osProfile.allowExtensionOperations to yes through powershell script for windows server.

If the Azure VMAgent is not provisioned or installed on an Azure VM, you will not be able to use any extensions with that VM
The error sound like VM Agent is not installed in the VM

So, the first step is to install VMAgent and Enable VM Extensions: Check the status of the agent

$vm = Get-AzVM -ResourceGroupName <RG name> -Name <vm name>  
$vm.OSProfile.WindowsConfiguration.ProvisionVMAgent  
$vm.OSProfile.AllowExtensionOperations

If you see the, result of final command as 'False', you need to download and install VMAgent in the VM. Manual installation may be necessary when you create a custom VM image that is deployed to Azure. To manually install the Windows VM Agent, download the VM Agent installer and select the latest release

It is important to update the AllowExtensionOperations option after manually installing the VMAgent on a VM that was deployed from image without ProvisionVMAgent enable using the following scripts

$vm.OSProfile.AllowExtensionOperations = $true  
$vm | Update-AzVM

Once the option is enabled you should now be able to install and use extensions on the Azure VM.

I have gone through this and I don't get a True or False after manually installing the Agent and running the 2 commands after assigning the vm to the $vm variable.
Also, I get the following error (as if it doesn't even exist)

PS C:\Windows\system32> $vm.OSProfile.AllowExtensionOperations = $true
The property 'AllowExtensionOperations' cannot be found on this object. Verify that the property exists and can be set.

For your info:

So, we have to go for any other convenient way to push the agent. One of the examples is as below:

Download and install the latest version of the agent installation package from here

msiexec.exe /i c:\VMAgentMSI\WindowsAzureVmAgent.2.7.<version>.fre.msi /quiet /L*v c:\VMAgentMSI\msiexec.log

Update agents in VMs:

Get-AzureVM  | where { $_.GuestAgentStatus -eq $null } | ForEach { $_.VM.ProvisionGuestAgent = $true;Update-AzureVM -VM $_.VM -Name $_.Name -ServiceName $_.ServiceName}

Check the status of the agent:

Get-AzureVM  | select -Property ServiceName,Name,@{Name=”GuestAgentStatus”; Expression={$_.GuestAgentStatus.Status}}

@Manu Philip I am using below script as I have to do it for multiple VMS. it's taking alot of time and then timing out. It is not installing the agent. I have required permissions also. What is the expected time to install it remotely using script

$rg = ""
$vms = (Get-AzVM -ResourceGroupName $rg).Name
$vm = (Get-AzVM -ResourceGroupName $rg)
$vm.OSProfile.AllowExtensionOperations = $true
$vm | Update-AzVM

$scriptBlock = @"
New-Item -ItemType Directory -Path "C:\temp"
Set-location "C:\temp"
Invoke-WebRequest -Uri https://go.microsoft.com/fwlink/?LinkID=394789 -OutFile VmAgent.msi
Get-ChildItem | Where-Object {$_.Name -eq 'VmAgent.msi'}
Start-Process "msiexec.exe" -Wait -NoNewWindow ;
Return $(Get-WmiObject -Class Win32_Product | Format-List);

"@

$scriptPath = "runID.ps1" Out-File -FilePath $scriptPath -InputObject $scriptBlock $response = Invoke-AzVMRunCommand -ResourceGroupName $rg -VMName $vms -CommandId 'RunPowerShellScript' -ScriptPath 'runID.ps1' $output = $response.value[0].message $output
