What is connection monitor feature in Azure Network Watcher good for?

Connection Monitor provides unified, end-to-end connection monitoring in Azure Network Watcher. The Connection Monitor feature supports hybrid and Azure cloud deployments. Network Watcher provides tools to monitor, diagnose, and view connectivity-related metrics for your Azure deployments.

Here are some use cases for Connection Monitor:

Your front-end web server virtual machine (VM) or virtual machine scale set (VMSS) communicates with a database server VM in a multi-tier application. You want to check network connectivity between the two VM/or scale sets.

You want VMs/scale sets in, for example, the East US region to ping VMs/scale sets in the Central US region, and you want to compare cross-region network latencies.

You have multiple on-premises office sites, one in Seattle, Washington, for example, and another in Ashburn, Virginia. Your office sites connect to Microsoft 365 URLs. For your users of Microsoft 365 URLs, you want to compare the latencies between Seattle and Ashburn.

Your hybrid application needs connectivity to an Azure storage account endpoint. Your on-premises site and your Azure application connect to the same endpoint. You want to compare the latencies of the on-premises site with the latencies of the Azure application.

You want to check the connectivity between your on-premises setups and the Azure VMs/virtual machine scale sets that host your cloud application.

You want to check the connectivity from single or multiple instances of an Azure Virtual Machine Scale Set to your Azure or Non-Azure multi-tier application.
