SD-WAN branches, hubs, and controllers generate logs and events that Analytics nodes use to display topology views, availability reports, traffic visibility reports, and SLA metrics. To capture the traffic to be monitored and analyzed by Analytics nodes, you associate a LEF profile with a feature or service configuration on VOS devices. For more information about associating LEF profiles with features and services, see Apply Log Export Functionality.

This articles describes the SD-WAN dashboards, which are located at Analytics > Dashboard (Home) Dashboard_icon.png > Dashboards > SD-WAN:

  • Top-level SD-WAN dashboard—Displays summary information about an SD-WAN site (tenant) or sites (tenants)
  • SD-WAN Sites dashboard—Displays SD-WAN traffic usage for a tenant
  • SD-WAN Sites Map dashboard—Displays a map providing a global view of device locations, site availability, and traffic activity between sites
  • SD-WAN Paths dashboard—Displays information about the paths between VOS devices

For general information about how to use an Analytics dashboard, see View Analytics Dashboards and Log Screens.

Top-Level SD-WAN Dashboard

To view summary information about a site or sites for an organization, select the top-level SD-WAN dashboard, at Analytics > Dashboard (Home) Dashboard_icon.png > Dashboards > SD-WAN.

The Analytics > Dashboard (Home) Dashboard_icon.png > Dashboards > SD-WAN dashboard displays summary information about the site or sites for the organization that is selected in the first drop-down menu in the main pane. (In the screenshot below, the organization is Corp-Inline-Customer-1.) When you select All Sites in the third drop-down menu, the top-level SD-WAN dashboard includes a statistics block at the top of the dashboard. For information about statistics blocks, see View Analytics Dashboards and Log Screens.

SD-WAN Paths Dashboard

WAN links are often referred to as circuits. While you configure circuit and path priority together, circuits and paths are different. A circuit is a WAN endpoint on a VOS branch device, and a path runs end to end from a local branch to a remote branch, in the process traversing a local circuit (that is, a local WAN endpoint) and a remote circuit (a remote WAN endpoint). For example, suppose Branch-1 and Branch-2 each have two WAN circuits, called Internet-1 and Internet-2. These circuits allow for four paths between Branch-1 and Branch-2:

  • Branch-1–Internet-1 → Branch-2–Internet-1
  • Branch-1–Internet-1 → Branch-2–Internet-2
  • Branch-1–Internet-2 → Branch-2–Internet-1
  • Branch-1–Internet-2 → Branch-2–Internet-2

To display information about paths between VOS devices, select Analytics > Dashboard (Home) Dashboard_icon.png > Dashboards > SD-WAN > Paths.

The SD-WAN Paths dashboard has the following tabs in the horizontal menu bar:

APM Tab

The APM tab displays TCP application performance metrics (APM) for all TCP-based traffic. When you enable TCP performance monitoring on VOS devices running SD-WAN, statistics corresponding to TCP sessions are exported to Analytics nodes. The statistics are aggregated per tenant, appliance, application, source, destination prefix, and WAN link. The metrics include round-trip time, aborted and refused counts, session and packet counts, and retransmission counts. These metrics are used to calculate the quality of the application, which is called the Versa application rank. This rank is computed as a value from 1 through 100, where 1 is the best performing application and 100 is the worst.

For releases prior to Release 22.1.1, the APM tab displays TCP application performance information.

For Releases 22.1.1 and later, the APM dashboard displays tabs for passive APM and active APM. The Passive APM tab displays performance monitoring information for TCP applications. The Active APM tab displays performance monitoring information for SaaS applications. For information about passive APM, see Configure Application Performance Monitoring.
