1. Overview
- What is ? Is the main dashboard which gives an overview of network performance.
- An explanation: The central location to access features for network diagnostics, monitoring and management.
2. Topology
- What visual map of network resources and connections.
- Explained: Displays the connection between resources such as virtual machines, subnets and gateways.
3. Troubleshooting
