SD-WAN Dashboards
For supported software information, click here.
Versa SD-WAN operates on Versa Operating SystemTM (VOSTM) devices, such as branches, hubs, and Controllers. These devices export logs with SD-WAN statistics to Analytics clusters, where they are used to generate charts, maps, and tables that you can view from dashboards in Versa Director.
This articles describes the SD-WAN dashboards, which are located at Analytics > Dashboards > SD-WAN. You can view the following SD-WAN dashboards:
- SD-WAN top level dashboard—Displays summary information for multiple VOS devices.
- Sites dashboard—Displays SD-WAN traffic usage for multiple VOS devices.
- Sites Map dashboard—Displays maps providing views for one or more VOS devices.
- Paths dashboard—Displays information about the paths between VOS devices.
- Device Details dashboard—Displays information about a single VOS device.
Note that the top level SD-WAN dashboard and SD-WAN Sites dashboards display information for groups of VOS devices only. You can view information for all devices or you can select a site tag to view information for the group of devices associated with the tag. Site tags are user-defined and appear in dashboard drop-down lists approximately 15 minutes after they are configured. For information about how to configure site tags, see Configure and Use Site Tags in View Analytics Dashboards and Log Screens.
For general information about how to use an Analytics dashboard, see View Analytics Dashboards and Log Screens.
Top-Level SD-WAN Dashboard

Paths Dashboard
WAN links are often referred to as circuits. 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 view information about paths between VOS devices, select Analytics > Dashboard > SD-WAN > Paths. Then, in the second drop-down list, select a device at one end of a path, referred to as the from-site. By default, paths between the from-site and all other VOS devices are displayed. You can select a device from the third drop-down list to view only the paths to a single device. This device is referred to as the to-site.
The following example displays the drop-down lists for the dashboard at Analytics > Dashboard > SD-WAN > Paths. In the second drop-down list, the from-site is Azure-WestUS-VGW-01. In the third drop-down list, no to-site has been selected. This dashboard displays paths between VOS device Azure-WestUS-VGW-01 and all other VOS devices to which the device has formed paths.

- Down—Availability is less than 10%. This state indicates either no activity from the site or SLA loss > 98%. For the most recent time displayed on the chart, there must be at least 10 minutes of inactivity before the link is marked as down.
- Degraded—If availability is ≥ 10% but < 95%. This state signifies brownout conditions detected by SLA loss values ≥ 50%. If link availability is greater than or equal to 10% but less than 95%, the links is marked as degraded. This state signifies brownout conditions detected by SLA loss values of greater than or equal to 50%.
- Up—Device availability is greater than or equal to 95%.
- Indeterminable—Applicable for most recent time when there is no activity for a minimum of 5 minutes.
Note: Overall site availability percentage is impacted only if the site is in down state during any 5-minute period. It is not affected by the degraded state, as there is still some activity from the site during this time.
- Service Uptime of device
- Data Plane Connectivity over Time of device—Reflects the SD-WAN site's reachability to any remote sites or hubs (excluding controllers) through WAN links. Dataplane states of down, degraded, and up are determined for each time block based on the downtime data, measured in seconds, that is periodically sent from the site.
The downtime percentage for a time block is calculated using the following formula:
Downtime-percentage = Downtime-in-seconds / Total-seconds
Dataplane states are based on the following:- Down—Downtime percentage is greater than 98%
- Degraded—Downtime percentage is greater than 2% and less than or equal to 98%
- Up—Downtime percentage is less than 2%
- Indeterminable—Applicable for any 5-minute time block with no data.
Note: Overall availability calculations use only the available data. Time blocks with no data due to control plane reachability issues are excluded from the computation.
- Connectivity Statistics of device
- Link Availability of device—Health of the VOS device WAN link's reachability to remote sites. Link availability states are based on the following:
- Down—If link availability is less than 10% due to no SLA activity or if SLA loss is less than 98%, the link is marked as down. For the most recent time displayed on the chart, the VOS device waits for at least 10 minutes of inactivity before marking the link as down.
- Degraded—If link availability is greater than or equal to 10% but less than 95%, the links is marked as degraded. This state signifies brownout conditions detected by SLA loss values of greater than or equal to 50%.
- Up—When link availability is greater than or equal to 95%, the link is marked as up.
- Indeterminable—Applicable for most recent time when there is no SLA activity for the link for a minimum of 5 minutes.
Note: Overall link availability percentage is impacted only when the link is in a down state during any 5-minute period.
