Monitoring Elements<\/strong><\/p>\n<ul>\n<li><strong>Network Monitoring:<\/strong> Monitors endpoints like virtual machines (VMs), fully qualified domain names (FQDNs), URIs, or IPv4 addresses. Connection Monitor reports on communication metrics such as reachability, latency, and network topology changes between two endpoints.<\/li>\n<li><strong>Network Performance Monitor:<\/strong> Verifies and reports on performance between various network infrastructure endpoints, including detection of issues like traffic blackholing and routing errors. It also monitors network links to on-premises infrastructure through VPN or Azure ExpressRoute.<\/li>\n<li><strong>Infrastructure Topology Diagrams:<\/strong> Provides visual representations of infrastructure topology, outlining virtual networks, subnets, resources, and network security groups.<\/li>\n<\/ul>\n<p><strong>2. Network Diagnostic Tools<\/strong><\/p>\n<p><strong>Diagnosing Network Traffic Filtering Issues for a Virtual Machine:<\/strong> When deploying a virtual machine in Azure, default security rules are applied to control incoming and outgoing traffic. Users can customize or add rules as needed. The IP flow verify capability allows specific configuration of resources, destination protocols, ports, IPv4 addresses, and traffic directions to troubleshoot and diagnose network traffic filtering problems.<\/p>\n<p><strong>Diagnosing Network Routing Problems for a Virtual Machine:<\/strong> Azure establishes default outbound routes for network traffic when creating a virtual network. These routes guide traffic from all resources, including virtual machines within the virtual network. Users have the flexibility to override default routes or create additional Azure default routes to address and diagnose network routing issues for virtual machines.<\/p>\n<p><strong>Capturing Packets to and from a Virtual Machine:<\/strong> Azure provides comprehensive packet capture capabilities with fine-tuned controls and advanced filtering options. Users can set size limitations and time parameters, offering versatility in capturing packets. Captured data can be stored on the virtual machine&#8217;s disk, in Azure Storage, or both, facilitating effective diagnosis of network communication issues.<\/p>\n<p><strong>Diagnosing Azure Virtual Network Gateway and Connections Issues:<\/strong> The Azure virtual network gateway establishes connectivity between Azure virtual networks and on-premises resources.
