The Network Overview feature helps to monitor networks by checking the Edge and Link (activated Edge) status summary. Clicking Monitor > Network Overview in the navigation panel opens the Network Overview screen, which provides a visual summary about the enterprises running SD-WAN Edge devices, Non VMware SD-WAN Sites, profiles, segments, software versions, and their system configuration time and run time statuses.

The following table describes the connection status types and definitions for the Edge, Edge Hub, Link, and Hub Link:

The Network Overview screen presents the overall summary information about a network in three dashboard sections:

    • Total number of Edge Hubs
    • Total number of Links
    • Total number of Hub Links
    • Count of Edges/Edge Hubs (Connected, Degraded, and Down)
    • Count of Link/Hub Links (Stable, Unstable, and Down)
  • Summary dashboard table - Includes a table that displays top ten Edges, or Edge Hubs, or Links, or Hub Links sorted by last contact time, based on the selected filter criteria in the SD-WAN Edge statistics section.
  • Non-Edge statistics - Includes the following non-edge related information:
    • Total number of Virtual Network Functions (VNFs)-enabled Edges
    • Count of VNFs-enabled Edges (Error, On, and Off)
    • Total number of VMware Active Standby Pair-enabled Edges
    • Count of VMware Active Standby Pair-enabled Edges (Failed, Pending, and Ready)
