ADEM calculates the experience score for each active as well as backup path as well as
for each application

ADEM discovers the various paths to be monitored based on the application forwarding
policies configured on Prisma SD-WAN devices. ADEM runs synthetics test
on all active and backup paths per application and calculates the experience score per
path, per application, and per site which rolls up from all remote site as organization
experience score.
Remote Site Experience Score
The remote site experience score is an average of all test sample
results that are collected from individual applications monitored
for that remote site.
Organization Experience Score
The organization experience score for remote sites is an average
of all test sample results that are collected from individual applications
monitored on all remote sites.
Experience Score for Each Path
For each path (active and backup path) that is discovered by ADEM based on the application
forwarding policy configured on Prisma SD-WAN devices, ADEM collects the
following metrics:
Application reachability
DNS resolution time
TCP connect time
SSL connect time
HTTP latency
Each of the above metrics (other than application reachability) have a different scores and
baselined lower and upper thresholds, and their combined score equals 100. The sum of
these individual metric scores determines the experience score for each path. If the
application reachability is zero, then the experience score for that path will also be
zero. If the application is reachable, only then the remaining four metrics will be
calculated.
Application Experience Score
The application experience score per remote site is an average of test samples collected from all
active paths. For example, if an application for a remote site is monitored on two
active and two backup paths, the average of test sample results from all active paths
will be considered as an experience score for that application monitored on that remote
site.
