#1 Analyze and evaluate your End-user satisfaction with Apdex

Apdex score refers to the Application Performance Index. Atatus has been the best APM solution provider for a long time and uses the Apdex score to measure the user experience and satisfaction.

Generally, the definition of Apdex score conveys how well the application is performed as well as the end-user satisfaction via the graphs.

Suppose you already define a response time threshhold T, all your users expect the web application to respond in T or less than T.

For instance, assume T=1.4 sec, and all the responses are completed in 0.5 sec, then your users are satisfied. If the responses are completed more than 1.4 sec, then your users are dissatisfied. Frustrated users are the ones whose response time is greater than 4T (i.e., 5.6 sec)
