Get Azure VM Boot Diagnostics and filter some string to print out to the console using powershell.

Question

Get Azure VM Boot Diagnostics and filter some string to print out to the console using powershell.

I have used the below script using parameters :

param(
[Parameter(Mandatory=$true)]
[string]$vm,
[Parameter(Mandatory=$true)]
[string]$resourcegroup,
[Parameter(Mandatory=$true)]
[string]$storageaccountname,
[Parameter(Mandatory=$true)]
[string]$localpath
)

$vm = Get-AzureRmVM -ResourceGroupName $resourcegroup -Name $vm
Set-AzureRmVMBootDiagnostics -VM $VM -Enable -ResourceGroupName $resourcegroup -StorageAccountName $storageaccountname
Set-AzureRmVMBootDiagnostics -VM $VM -Enable -ResourceGroupName $resourcegroup -StorageAccountName $storageaccountname |Update-AzurermVM

Get-AzureRmVMBootDiagnosticsData -ResourceGroupName $resourcegroup -Name $vm -Windows -LocalPath $localpath

Output is getting error :

cmdlet Task3.1.ps1 at command pipeline position 1
Supply values for the following parameters:
vm: azbootvm
resourcegroup: AzRg

First of all I would recommend to use Az instead of AzureRM because AzureRM is outdated.
https://learn.microsoft.com/de-de/powershell/azure/migrate-from-azurerm-to-az?view=azps-5.2.0

I would start with getting the Azure ResourceGroup object:

...  
$resourcegroup = Get-AzureRmResourceGroup -Name $resourcegroup  
$vm = Get-AzureRmVM -ResourceGroupName $resourcegroup -Name $vm  
...  

It could be helpful for troubleshooting to output both variables just to see if objects are found (later you can delete the output again):

$resourcegroup = Get-AzureRmResourceGroup -Name $resourcegroup  
$resourcegroup  
$vm = Get-AzureRmVM -ResourceGroupName $resourcegroup -Name $vm  
$vm  
  

Check the output of $vm which type it is with $vm.GetType() . The type needs to be Microsoft.Azure.Commands.Compute.Models.PSVirtualMachine
