Experience Score Cards
Select the Mobile User Experience card to see only the Mobile
User related data displayed in the widgets underneath. Likewise, clicking the
Remote Site Experience card displays data specific to
Remote Sites only in the widgets that follow.
The number enclosed in the rectangle is the
Experience Score, which is a
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.
The Monitored Applications graph is color coded to show you
the number of applications that have Good (green), Fair (yellow), and Poor (red)
experience scores. An application experience score >= 70 is Good, 69-30 is Fair, and
below 30 is Poor.
