About the WAN Health Tab

To access this tab, click Observability > Health > Health Dashboard > WAN Health.

This tab provides a unified view of the overall health of devices, interfaces, and routing neighbors in your network in real-time. You can monitor overall health and use this health-related data to perform corrective actions when necessary.

The WAN Health tab consists of the following accordions:

  • Devices Health

  • Interfaces Health

  • Routing Health

Each accordion has three sections. The first section provides a description of the accordion. The second section displays the latest aggregate health snapshot. The last section displays a health trend graph representing the average health for the past 30 minutes.
