  • 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.

Application Performance Metrics

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.
