Experience Score
The
Experience Score is the weighted average
of end-to-end application performance metrics for all monitored
applications across all users or remote sites. A fair or poor experience
score lets you know right away that there are performance issues
impacting a large number of your users or remote sites. However,
because the experience score is weighted, it may not uncover performance
issues in monitored apps or locations that have a smaller number
of users.
The experience score will also give you an indication of the
overall digital experience for the user. For each application that
is monitored per mobile user, ADEM calculates a score based on the
5 critical metrics - application availability, DNS resolution time,
TCP connect time, SSL connect time, and the HTTP latency. If the
application fails the availability test (application is unavailable),
then the experience score is 0. If the application is reachable,
only then the remaining four metrics will be calculated. Each of
the above metrics (other than application reachability) have a different
weightage and baselined lower and upper thresholds, and their combined weightage
equals 100. The sum of these individual metric scores determines
the application experience score for a user. An average of all the
test sample results for each application determines the experience
score of a user.
Experience scores are color coded in widgets as follows:
Good (green) - experience score >=70
Fair (orange) - experience score is 69-30
Poor (red) - experience score is <30
