Apdex is a performance-measurement standard that strives to show the relationship between recorded performance measurements and real-user satisfaction. It offers a uniform means of measuring how well performance meets user expectations. Apdex is used to give you a quick and easy rating that you can use to evaluate the satisfaction of your application’s end users. Apdex ratings in Dynatrace are based on the application-specific thresholds. An apdex measurement rating of 1 equates to perfect performance. An Apdex rating below 0.5 equates to poor performance.

Benefits of Apdex ratings

  • Apdex ratings give you a quick and easy way of evaluating the performance of all user actions that you are monitoring: a value of 1 is perfect; values below 0.5 are poor.
  • You can use Adpex ratings as benchmarks and compare two applications over time, even though the timing thresholds set up for the two applications may be different.
  • Applications are typically comprised of many different user action types. For example, it might be acceptable to have a complex search in an application take up to 6 seconds to complete while the loading of the homepage in the same application might need to take less than 2 seconds to ensure user satisfaction. Such differences can be addressed by configuring different Apdex thresholds for these two different user action types.
