When you drill down, the experience score for a remote site gives
you an indication if the site is performing good, fair, or poor.
The site experience score is an average score of all monitored applications
on all active WAN paths. It is an average of all test sample results
that are collected from individual applications monitored for that
remote site.
Application Experience Details
View the detailed metrics for each application running
on your remote site.
Application Cards - Each application card shows you the
experience score for the particular application on the remote site.
The number enclosed in the square shows the end-to-end experience
for the active paths of the application. It is the average of all
test samples collected on the active paths for that specific application
only. See Calculating Experience Score for Remote Sites for details
on how the experience scores are calculated for remote sites.
You
can see how many applications you are monitoring and also how many active
and backup paths are monitored. Each application card shows the number
of paths that are impacted. The red or yellow dots in the legend
indicate that the path is impacted. Green stands for good.
Click
an application card to see the metrics for that specific app.
Total Paths - See the number of active and backup paths that
are being monitored for the selected application, the type of paths
used. The number enclosed in the square is the experience score
for its active path as well as its backup path. See Calculating Experience Score for Remote Sites for details
on how the experience scores are calculated for remote sites.
For
both active and backup paths of an application, ADEM collects the following
information, which is different for each type of path:

The types of paths (Prisma
Access path (standard VPN), Secure Fabric path, or Direct Access
path).
Its source circuit and destination termination points. Click
on a type of path (active or backup) to see the filtered data for
that path type only in the widgets that follow.
Application Experience Trend
- Hover
your mouse cursor on an application trend line in the application
card to see the experience scores at any point in time during the
given interval.

- This
chart allows you to quickly pinpoint which segment of the end-to-end
experience is likely causing the issue— segments starting from the
remote site, ISP or WAN, or the application itself—might be the
cause of the issue. For each segment, you can get the trends by
clicking on the node. For example, if you click on the Prisma SD_WAN
Branch node you get the CPU and memory trend, clicking on Internet
will display latency, jitter, and packet loss trend. Click on a segment,
such as Device, Prisma SD-WAN Branch, Internet, Prisma Access, or the
app name to view the associated data for that segment in the
