As we have already discussed the basics in Chapter 4, Networking Design and Management, let's explore it in detail. While the Microsoft OMS and the Azure Monitor are more general tools for management and monitoring, the tool I'm going to present is specifically designed for Azure networking is the Azure Network Watcher.

The Azure Network Watcher is a service that allows you to monitor and diagnose conditions at the level of network scenarios in Azure. The included tools for network diagnostics and visualization help you understand your network in Azure, perform diagnostics, and gain insights.

Currently, the Azure Network Watcher has the following features:

• Topology: Visualize your network topology
• Network diagnostics: Diagnostic tools for networking related issues:
  • Variable packet capture
  • IP flow verify
  • Security group view
  • Next hop
  • VPN troubleshooting
  • Connectivity check
• Metric: Measure and view of your network performance and health
  • Network subscription limits
• Logs: Configure and view your logs
  • Network security group flow logs
