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.
