Azure Network Watcher tools

Monitoring tools

• Network Topology generates a visualization of the entire network for understanding network configuration.
• Connection monitor provides end-to-end connection monitoring for Azure and hybrid endpoints.

Diagnostic tools

• IP Flow Verify helps you to detect traffic filtering issues at a virtual machine level. It checks if a packet is allowed or denied to or from an IP address (IPv4 or IPv6 address). It also tells you which security rule allowed or denied the traffic.

• Next Hop helps you detect routing issues. It checks if traffic is routed correctly to the intended destination.

• Effective security rules shows you all security rules applied to the network interface, the subnet the network interface is in, and the aggregate of both.

• Connection troubleshoot tests connections between resources. For example, a virtual machine, a virtual machine scale set, or an application gateway.

• Packet Capture lets you remotely create packet capture sessions to record all network traffic to and from a virtual machine (VM) or a virtual machine scale set.

• VPN troubleshoot enables you to troubleshoot virtual network gateways and their connections.

Traffic tools

• Flow logs allows you to log information about your Azure IP traffic and stores the data in Azure storage. You can log IP traffic flowing through a network security group or Azure virtual network.

• Traffic analytics provides rich visualizations of flow logs data.
