Collecting data from a development or test environment

Collecting realtime performance data
You can profile (collect performance data from) a running distributed J2EE application in a development environment.
Collecting data from an application in an automated test environment
You can also profile applications as the are exercised by automated testing tools which free you from having to repeatedly run the problem scenario, and which can simulate load on the application.
Collecting data from a Web service using Maelstrom
You can profile a Web service component of an application using the Maelstrom engine in WebSphere® Application Server.
Collecting data from non-J2EE applications
You can profile non-J2EE Java™ applications, or applications in any other language supported by the ARM standard.

Once you have collected the performance data, you can begin analyzing it and diagnosing the problem. You can view the data using several views including statistics views and sequence diagrams of class and object interactions.
