Retrieve Azure VM details by using PowerShell.

Recently I built a large environment in Azure with more than 1000 Virtual machines. Now we need to provide the Virtual Machine details to the customer(or raise the SNOW ticket) and it is very difficult to collect each VM detail manually from Azure Portal. Also, there can be another use case if you want to verify the VMs to compare with each other to ensure all the VMs are created the same way. For example Cache setting for all the VMs should be Read /Write. You may also want to grab details of all the data disks and OS disks and their size, name info and cache settings. This script grabs all the info in one shot and exports it into a CSV file for further manipulation. This script also provides Private and Public IP addresses.

# Connect to Azure Account
Connect-AzAccount

# Create Report Array
$report = @()

# Record all the subscriptions in a Text file
$SubscriptionIds = Get-Content -Path "c:\inputs\Subscriptions.txt"
Foreach ($SubscriptionId in $SubscriptionIds)
{
$reportName = "VM-Details.csv"

# Select the subscription
Select-AzSubscription $subscriptionId

# Get all the VMs from the selected subscription
$vms = Get-AzVM

# Get all the Public IP Address
$publicIps = Get-AzPublicIpAddress

# Get all the Network Interfaces
$nics = Get-AzNetworkInterface | ?{ $_.VirtualMachine -NE $null}
foreach ($nic in $nics) {
    # Creating the Report Header we have taken maxium 5 disks but you can extend it based on your need
