How to get all resources used in a azure subscription

 You can list all resources in an Azure subscription in several ways—Azure Portal, Azure CLI, PowerShell, or REST API.

Here’s a detailed guide for each approach:

---

✅ 1. Azure Portal (UI method)

1. Sign in to Azure Portal.

2. Go to All resources (left menu → All services → search for “All resources”).

3. At the top:

   • Filter by subscription (if you have multiple).

   • Optionally filter by resource group, location, or type.

4. Click Download CSV (at the top right) to export the list.

👉 Result: A spreadsheet with all resources across the selected subscription.

✅ 2. Azure CLI

a. Install & Log in

az login
az account set --subscription "<your-subscription-name-or-id>"

b. List all resources

az resource list --output table

• --output table → pretty table

• Other formats: json, jsonc, yaml

c. Filter or export

# Filter by resource group
az resource list --resource-group MyRG --output table

# Export to a JSON file
az resource list --output json > all-resources.json

---

✅ 3. Azure PowerShell

a. Connect

Connect-AzAccount
Set-AzContext -Subscription "<your-subscription-id>"

b. List resources

Get-AzResource | Format-Table

c. Export to CSV

Get-AzResource | Export-Csv -Path .\all-resources.csv -NoTypeInformation

---

✅ 4. Azure Resource Graph (Recommended for Large Subscriptions)

Faster and more scalable.

1. In the Azure Portal, search Resource Graph Explorer.

2. Run a Kusto Query:

resources
| project name, type, location, resourceGroup, subscriptionId
| order by type asc

3. Export results (CSV/JSON).

---

✅ 5. Azure REST API

For automation or custom apps:

GET https://management.azure.com/subscriptions/{subscriptionId}/resources?api-version=2021-04-01
Authorization: Bearer <token>

• Use az account get-access-token to get a token.

---

🔹 Best Practice

• For one-time inventory, Azure CLI/Portal CSV export is simplest.

• For regular audits, schedule a Resource Graph query or use Azure Policy + Cost Management.

• For automation, use REST API or PowerShell in a script.

💡 Tip: If you have multiple subscriptions, run:

az account list --output table

…then loop through each subscription to collect all resources.
