The topic of today's post is Azure Network Watcher IP Flow.  Azure Network Watcher is a powerful tool that can analyze network traffic, to help users to resolve network problems, with your organization virtual machines.  It's a quick and simple tool to diagnose connectivity issues to or from other Azure resources, the internet, and on-premises environment.  I have an example of how Azure Network Watcher IP flow works, I would like to talk about in the next paragraph.

As a user's your organization deploys several virtual machines on premises and offloads some of the services to the cloud, with Expressroute.   Expressroute is being deployed, and configured on premise virtual machines, with Azure connectivity.  Some virtual machines are having network connectivity issues.

With Azure Network Watcher IP Flow users can analyze the network traffic to identify whether packets are being allowed or denied to the virtual machines. It helps you to troubleshoot virtual machine connectivity issues by checking network security group rules and Azure Virtual Network Manager admin rules, link below to Microsoft website with more information.
