Monitor and troubleshoot Azure & hybrid networks with Azure Network Monitoring
Azure Network Watcher and Network Insights portfolio encompasses an entire suite of tools to visualize, monitor, diagnose, and troubleshoot network issues across Azure and Hybrid cloud environments. The suite enables customers to observe health across resources and networks with comprehensive wide coverage, through a guided and intuitive drilled down experience with Network Insights. Moreover, users can detect and localize connectivity and performance issues across their Azure and Hybrid networks with synthetic monitoring in Connection Monitor. Additionally, Traffic Analytics allows customers to visualize and manage their networks for uncompromised security, compliance issues, and understand the flow of network traffic. Lastly, the Diagnostics suite offers fast troubleshooting with actionable insights, thus effectively assisting in reducing the meantime to resolve and mitigate network issues
New and improved network topology experience in Network Watcher and Azure Monitor Network Insights
Azure Network Watcher provides network monitoring and troubleshooting capabilities to increase observability and actionable insights. Network Watcher supports four main scenarios: Connectivity Monitoring detects packet loss and latency, built-in health metrics and topology visualization help to locate issues, traffic monitoring tracks network communication pattern, and diagnostics suite enables troubleshooting. Efficient management and monitoring of cloud networks is crucial for peak performance, security, and reliability. The blog explains how the new topology experience can help you manage and monitor your cloud network infrastructure with enhanced visualization, simplified monitoring, valuable insights and contextual issue localization capabilities.
Build an Azure Logic App to send an alert when the provisioning state changes for your Azure VWAN
Have you ever thought about monitoring your VWAN provisioning state? In today’s dynamic cloud environment, it’s crucial to have a good monitoring system in place for your Azure resources especially your networking resources. In this blog, I am going to show you step-by-step how to create an Azure Logic App that will notify you whenever the provisioning status of your Azure Virtual WAN changes to another state other than “Succeeded”. Note: As of the time I am writing this blog, Microsoft doesn’t support alerts based on Metrics for Azure Virtual WAN. You can still retrieve information for the components that shape up the Virtual WAN for example, VPN site-site connections, BGP peers, virtual hubs, etc. However, you won’t be able to configure diagnostic logs for virtual WAN at this time. Good news — There’s an alternate way to be alerted via an Azure Logic AppAzure virtual network terminal access point (TAP) public preview announcement
What is virtual network TAP? Virtual network TAP allows customers continuously stream virtual machine network traffic to a network packet collector or analytics tool. Many security and performance monitoring tools rely on packet-level insights that are difficult to access in cloud environments. Virtual network TAP bridges this gap by integrating with our industry partners to offer: Enhanced security and threat detection: Security teams can inspect full packet data in real-time to detect and respond to potential threats. Performance monitoring and troubleshooting: Operations teams can analyze live traffic patterns to identify bottlenecks, troubleshoot latency issues, and optimize application performance. Regulatory compliance: Organizations subject to compliance frameworks such as Health Insurance Portability and Accountability Act (HIPAA), and General Data Protection Regulation (GDPR) can use virtual network TAP to capture network activity for auditing and forensic investigations. Why use virtual network TAP? Unlike traditional packet capture solutions that require deploying additional agents or network appliances, virtual network TAP leverages Azure's native infrastructure to enable seamless traffic mirroring without complex configurations and without impacting the performance of the virtual machine. A key advantage is that mirrored traffic does not count towards virtual machine’s network limits, ensuring complete visibility without compromising application performance. Additionally, virtual network TAP supports all Azure virtual machine SKU. Deploying virtual network TAP The portal is a convenient way to get started with Azure virtual network TAP. However, if you have a lot of Azure resources and want to automate the setup you may want to use a PowerShell, CLI, or REST API. Add a TAP configuration on a network interface that is attached to a virtual machine deployed in your virtual network. The destination is a virtual network IP address in the same virtual network as the monitored network interface or a peered virtual network. The collector solution for virtual network TAP can be deployed behind an Azure Internal Load balancer for high availability. You can use the same virtual network TAP resource to aggregate traffic from multiple network interfaces in the same or different subscriptions. If the monitored network interfaces are in different subscriptions, the subscriptions must be associated to the same Microsoft Entra tenant. Additionally, the monitored network interfaces and the destination endpoint for aggregating the TAP traffic can be in peered virtual networks in the same region. Partnering with industry leaders to enhance network monitoring in Azure To maximize the value of virtual network TAP, we are proud to collaborate with industry-leading security and network visibility partners.

Issue with Azure VM Conditional Access for Office 365 and Dynamic Public IP Detection
Hi all, I have a VM in Azure where I need to allow an account with MFA to bypass the requirement on this specific server when using Office 365. I've tried to achieve this using Conditional Access by excluding locations, specifically the IP range of my Azure environment. Although I’ve disconnected any public IPs from this server, the Conditional Access policy still isn’t working as intended. The issue seems to be that it continues to detect a public IP, which changes frequently, making it impossible to exclude. What am I doing wrong?

Change subnet
we have the usual vnet setup with a/24 subnet split into /25 for vms and /27 for DMZ and /27 for Bastion. the users were running out of IP addresses for VM deployment. I have setup a vnet with a /24 subnet which can give them more IPs but, they want the bastion to be enabled for accessing the VMs. I made sure the VMs are turned off and tried changing the subnet /25 but it says it is in use,. Does Azure allow changing the subnet? I know I can add a whole new subnet for bastion but, I'm thinking about the possibility of changing the same subnet for keeping it organized.
