Monitor App and Link Performance

View a detailed, aggregated summary of all the application and link health data for a specific SD-WAN site. This allows you view which applications paths are experiencing degraded health. For your applications, you can view app health for each application, whether error correction was applied for impacted applications, and the number of error corrected sessions and impacted sessions out of the total number of sessions within the specified timeframe. Click on an
App
to monitor traffic characteristics for the selected application.
For your configured links, you can view whether error correction was applied for an impacted link, the number of notifications that were generated due to link health degradation, as well as the health status for latency, jitter, and packet loss for each link configured for the site.
Field
Description
App Performance
App
Name of the application specified by an SD-WAN policy rule.
SD-WAN Policies
Name of the SD-WAN policy rule(s) that matched the app traffic matched. Multiple SD-WAN policy rules may be listed if the app traffic matched multiple SD-WAN policies.
SaaS Monitoring
Displays whether the app is a SaaS application configured in a SaaS Quality profile that is associated with one or more SD-WAN policy rules.
  • Disabled
    —The app is not a SaaS application configured in a SaaS Quality profile.
  • Enabled
    —The app is a SaaS application configured in a SaaS Quality profile and is associated with a single SD-WAN policy.
  • Multiple
    —The app is a SaaS application configured in a SaaS Quality profile and is associated with a multiple SaaS Quality profiles.
App Health
Indicates the app health based on available links to swap to. Can be
Impacted

Warning
, or
OK
.
Error Correction Applied
Specifies the type of forward error correction applied. If empty (blank), then no error correction was applied.
  • FEC
    —Forward Error Correction
  • PD

Bytes
Total byte count of transfered data for the application within the specified time frame.
Error Correction Sessions/Impacted Sessions/Total Sessions
Number of error corrected sessions and impacted sessions out of the total number of sessions within the specified time frame. If the application is impacted, this helps indicate how extensive the issue is.
