Azure SDK for listing VMs and VMSS

Hi ,

Thanks for reaching out to Microsoft Q&A.

Yes, you can use the Azure SDK for Python (or other languages like C# or Java) to list Virtual Machines (VMs) and Virtual Machine Scale Sets (VMSS). Here's how you can achieve this using the Azure SDK for Python.

Prerequisites:

1. Install the required libraries --> pip install azure-mgmt-compute azure-identity
2. Set up your Azure credentials, such as using environment variables or Azure CLI login.

Main py code example as below, feel free to modify according to your env/requirements:

from azure.identity import DefaultAzureCredential
from azure.mgmt.compute import ComputeManagementClient

# Authenticate using Azure Default Credentials
credential = DefaultAzureCredential()
subscription_id = "your_subscription_id"

# Initialize Compute Management Client
compute_client = ComputeManagementClient(credential, subscription_id)

# List all Virtual Machine Scale Sets
print("Listing all VMSS in the subscription...")
for vmss in compute_client.virtual_machine_scale_sets.list_all():
    print(f"VMSS Name: {vmss.name}, Location: {vmss.location}")

    # List all instances (VMs) under the VMSS
    print(f"Listing VMs in VMSS: {vmss.name}")
    for vm in compute_client.virtual_machine_scale_set_vms.list(resource_group_name=vmss.resource_group_name, vm_scale_set_name=vmss.name):
        print(f"  VM Instance ID: {vm.instance_id}, Name: {vm.name}, Status: {vm.provisioning_state}")

Key Points:

1. virtual_machine_scale_sets.list_all():
   • Lists all VMSS resources in your subscription.
   1. virtual_machine_scale_set_vms.list():
      • Retrieves all VM instances within a specified VMSS.
2. DefaultAzureCredential:
   • Simplifies authentication using your environment or Azure CLI.

For Other Languages

• C#: Use Microsoft.Azure.Management.Compute to achieve the same.
• Java: Use com.azure.resourcemanager:azure-resourcemanager-compute
