Connection Monitor is a component of Azure Network Watcher. In the current Preview, it enhances the functionality by embedding Network Performance Monitor (NPM) feature into the Connection Monitor service. <\/p>More info: https:\/\/docs.microsoft.com\/en-us\/azure\/network-watcher\/connection-monitor-preview<\/a><\/cite><\/blockquote>\n\n\n\n

What is Network Watcher?<\/h3>\n\n\n\n

Network Watcher represents set of tools that help Network Administrators to monitor, diagnose, and review metrics in an Azure Virtual Network. The service works with Infrastructure services (IaaS), such as Virtual Machines, Network Virtual Appliances (NVA), Virtual Networks and inter-network connectivity (VPN, ExpressRoute), Application Gateway, Load Balancer. The solution is part of the Azure Monitor service, specifically Log Analytics.<\/p>\n\n\n\n

Four core functionalities are:<\/p>\n\n\n\n

  1. Monitoring<\/li>
  2. Diagnostics<\/li>
  3. Metrics<\/li>
  4. Log analysis <\/li><\/ol>\n\n\n\n

    Connection Monitor (in Preview)<\/h3>\n\n\n\n

    The Connection Monitor performs overview of communication between a virtual machine and specific endpoint. The endpoint can be another virtual machine, a fully qualified domain name (FQDN), a uniform resource identifier (URI), or IPv4 address. It performs the test in regular interval, and then presents the information about reachability, latency, performance (graph), and provides simple network topology diagram (cloud, on-premises, hybrid)<\/p>\n\n\n\n

    Network Performance monitoring, on other hand, represents a hybrid network monitoring solution, capable of analyzing the performance of various endpoints. It is capable of detecting various network infrastructure issues, such as traffic black-holing, routing errors, link threshold issues, performance issues on network segment or device. This an be done for cloud only, on-premises or hybrid services connectivity.<\/p>\n\n\n\n

    Benefits<\/h3>\n\n\n\n

    The Preview services combines two features – Connection Monitor and Network Performance Monitor, thus providing the following benefits:<\/p>\n\n\n\n
