Dump NMI Azure with Azure CLI and Azure AD

To dump NMI (Netdump) from Azure using the Azure CLI and Azure AD, you'll need to have the Azure CLI installed and configured on your machine. This will allow you to interact with your Azure resources.

The Azure CLI is a powerful tool for managing Azure resources, and it's free to use. You can download and install it from the official Azure website.

To use Azure AD with the Azure CLI, you'll need to register your application and grant it the necessary permissions. This will allow you to authenticate with Azure and access your resources.

Azure AD provides a secure way to authenticate with Azure, and it's a required step for using the Azure CLI.

Dump NMI is a troubleshooting tool used in Azure to diagnose issues related to Non-Maskable Interrupts (NMI) events.

A Non-Maskable Interrupt (NMI) is a type of hardware interrupt that cannot be masked or disabled by software.

NMIs are typically used to signal critical hardware errors or unexpected events that require immediate attention.

Dump NMI can help identify the root cause of NMI events by collecting and analyzing system data.

This data can include information about the system's hardware, software, and firmware configurations.

By analyzing this data, Azure administrators can troubleshoot and resolve NMI-related issues more efficiently.

Dump NMI is particularly useful for diagnosing issues related to Azure Virtual Machines (VMs) and Azure Kubernetes Service (AKS) clusters.

It's essential to understand that Dump NMI should only be used for troubleshooting purposes and should not be used as a regular monitoring tool.

To identify managed identities using the Azure CLI, you can authenticate as an Azure AD user and use the `az vm list` command to get a list of VMs.

You can then pipe that list into the command to show identities. This one-liner is a helpful way to identify managed identities in a subscription.

To make it easier to identify the specific managed identity, you can print the VM name, which is more intuitive than using the principalId.

Azure NMI is a feature that allows you to manage network interfaces on Azure virtual machines.

It's a game-changer for system administrators, as it eliminates the need to manually configure network interfaces one by one.

Azure NMI supports multiple network interfaces per virtual machine, and it's compatible with both Linux and Windows operating systems.

This feature is especially useful for scenarios where multiple network interfaces are required, such as with virtual machines that need to connect to different subnets or networks.

Azure NMI also supports dynamic network interface configuration, which means you can modify network interface settings without having to restart the virtual machine.

You can use Azure NMI with Azure CLI commands like az vm nic add and az vm nic remove to manage network interfaces on your virtual machines.

As an Azure AD user, you can use the AZ CLI to manage identities.

To identify managed identities, you can get a list of VMs using the command az vm list and pipe it into the command to show identities.

The principalId, a GUID, isn't the easiest thing to use to identify the specific managed identity.

Printing the VM name ($.name) first helps figure out which VM owns the identity, making it easier to manage.
