Display of Performance Data for Requests 

Use

With the Web Dynpro Console administration tool, you can display the performance data for the times of a request to the J2EE Engine. In contrast to tree items Web Dynpro Framework, Client and Applications, the data gives information about the response times of the individual steps of a request (starting within the J2EE Engine).

Prerequisites

You have administrator rights for the J2EE Engine or for SAP Enterprise Portal. If you do not have administrator rights, you can only access a small part of the monitoring information.

Features

Under the tree node Requests you get detailed information about the times needed to process a request within a request response cycle.

The table lists the requests sorted by the length of time. The required response time, the number of methods involved, the method taking the longest time, and the user are listed for each request.

When you select a line, you get detailed information for the particular request. The performance data for a request includes the framework, application, and backend times. The detailed information also includes the level of the methods, giving you information about the call depth of the methods called. You can thus find out which query took the longest and which methods within a query consumed time.

The detailed information includes the gross and net times for the individual methods. In order to interpret the performance data correctly, you should understand the difference between gross and net times of a method. The gross times are accumulated times including the times for the framework, application and backend. The net times are gross times minus the times for the framework, application and backend. It is thus possible to determine whether the method itself or the included parts are responsible for the performance problem.
