Today's focus:
Apdex interprets app measurements
By Peter Sevcik
Current application performance-measurement tools have several
limitations. Each has its own definition of performance,
produces too many confusing or conflicting numbers, and lacks a
simple summary result. IT managers have no insight into the
performance that matters - users' experience with
mission-critical applications.
A consortium of companies called the Apdex Alliance is
developing the Application Performance Index (Apdex) to specify
a uniform way to measure and report on the user experience.
Apdex is a numerical measure of user satisfaction with the
performance of enterprise applications. The metric gauges the
effectiveness of IT investments, and helps CIOs and other
executives understand whether their applications are delivering
on promises or just operating.
Implemented as a reporting window for current products, Apdex
converts application response time measurements from many tools
and services into a single number using a scale of 0-to-1 (0
equals no users satisfied, 1 equals all users satisfied).
Task response time is defined as the elapsed time between when a
user does something (mouse click, enter, return) and when the
system (client, network, servers) responds so that a user can
proceed with the process. These waiting periods define the
"responsiveness" of the application. The index is based on three
zones of application responsiveness.
To find out what the three zones of application responsiveness
are, please go to:
