What is the default APDEX calculation value?

The default APDEX (Application Performance Index) calculation value is 3. This value is significant because it defines the threshold for user satisfaction in performance monitoring. APDEX is used to quantify the experience of users based on response times. The value is split into three categories: satisfied, tolerating, and frustrated.

In this framework, a response time that is at or below the predefined acceptable threshold is considered "satisfied" and is assigned a score of 1. Response times that fall between the acceptable threshold and a specified tolerance level are considered "tolerating" and get a score of 0.5, while response times above the tolerance limit are deemed "frustrated" and score 0. The high score of 3 indicates a favorable threshold that points toward optimal application performance, encouraging teams to focus on improving user experiences in critical thresholds defined by the APDEX score.

Understanding the correct default value is essential for effectively using Dynatrace to monitor application performance and improve user satisfaction.
