Azure Monitor for VM Insights is a feature of Azure Monitor that provides comprehensive monitoring and diagnostics for your Azure virtual machines and virtual machine scale sets. It collects performance data, process information, and network dependencies from your virtual machines and displays them in interactive charts and maps. You can use Azure Monitor for VM Insights to troubleshoot performance issues, optimize resource utilization, and identify network bottlenecks1.

To enable Azure Monitor for VM Insights, you need to install two agents on your virtual machines: the Azure Monitor agent (preview) and the Dependency agent. The Azure Monitor agent collects performance metrics and sends them to a Log Analytics workspace. The Dependency agent collects process information and network dependencies and sends them to the InsightsMetrics table in the same workspace2.

By default, the agents communicate with Azure Monitor over the public internet. However, if you want to ensure that all the virtual machines only communicate with Azure Monitor through a virtual network named VNet1, you need to configure private network access for the agents.

Private network access allows the agents to communicate with Azure Monitor using a private endpoint, which is a special network interface that connects your virtual network to an Azure service without exposing it to the public internet. A private endpoint uses a private IP address from your virtual network address space, so you can secure and control the network traffic between your virtual machines and Azure Monitor3.

To configure private network access for the agents, you need to create an Azure Monitor Private Link Scope (AMPIS) first. An AMPIS is a resource that groups one or more Log Analytics workspaces together and associates them with a private endpoint. An AMPIS allows you to manage the private connectivity settings for multiple workspaces in one place4.

After creating an AMPIS, you need to create a private endpoint in VNet1 and link it to the AMPIS. This will enable the agents on your virtual machines to send data to the Log Analytics workspaces in the AMPIS using the private IP address of the private endpoint5.

No, this does not meet the goal. Unregistering the Microsoft.ClassicNetwork provider does not affect the creation of network security groups (NSGs) in the subscription. The Microsoft.ClassicNetwork provider is used for managing classic deployment model resources, such as virtual networks, network interfaces, and public IP addresses1. However, NSGs are only supported for Resource Manager deployment model resources2. Therefore, unregistering the Microsoft.ClassicNetwork provider will not automatically block TCP port 8080 between the virtual networks.

To meet the goal, you need to create a custom policy definition that enforces a default security rule for NSGs. A policy definition is a set of rules and actions that Azure performs when evaluating your resources3. You can use a policy definition to specify the required properties and values for NSGs, such as the direction, protocol, source, destination, and port of the security rule. You can then assign the policy definition to the subscription scope, so that it applies to all the resource groups and virtual networks in the subscription.

To use Traffic Analytics in Azure Network Watcher, you need to create a Log Analytics workspace and a storage account. A Log Analytics workspace is a cloud-based repository that collects and stores data from various sources, such as NSG flow logs. A storage account is a container that provides a unique namespace to store and access your data objects in Azure Storage. You need to enable NSG flow logs and configure them to send data to both the Log Analytics workspace and the storage account. Traffic Analytics analyzes the NSG flow logs and provides insights into traffic flow in your Azure cloud.

Azure Disk Encryption is a service that helps you encrypt your Windows and Linux IaaS virtual machine disks1. It uses BitLocker for Windows and DM-Crypt for Linux to provide volume encryption for the OS and data disks2. Azure Disk Encryption requires that you use a key encryption key in Azure Key Vault to encrypt the volume encryption key, which is then stored on the disk. You can use either a service-managed key or a customer-managed key in Azure Key Vault3. Azure Disk Encryption also supports encrypting virtual machine disks that are downloaded from Azure4.
