Calculating Experience Score for Remote Sites
If you are using the Strata Cloud Manager user interface, see
the AI-Powered ADEM Administrator's Guide.
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) which 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.
