Procedure documentation Displaying the Response Time Distribution  Locate the document in its SAP Library structure

Use

In the workload monitor, you can display the workload in different analysis views which highlight the workload from a particular perspective. One of these aspects is the question of how response times are distributed with respect to the different task types.

The response time for the transaction steps is split into 10 categories: t < 0.1 s; 0.1 s < t < 0.2 s, and so on You can choose between two different types of display:

·        Number of transaction steps (absolute or percentage) that are in a particular response time category (such as a response time between 0.4 s and 0.5 s).

·        Percentage of transaction steps whose response time is not longer than the upper limit of a particular response time category (such as a response time between 0 s and 0.5 s).

This analysis view therefore allows you to check quickly what percentage of all transaction steps have a response time below a certain threshold value.

For more information about what response time you can expect, see: Response Times: Rough Guide.

Note

Since the response time has included the communication between the SAP system and the presentation server since SAP R/3 4.6 (see also SAP Note 203924), you can display the response time for the Dialog task type either including or excluding the GUI time in this analysis view.

In this way, you can remove the influence of the performance of the front end systems and the network from the calculation of the response time distribution.

Procedure

...

       1.      Start the Workload Monitor by calling transaction ST03.

       2.      In the Workload tree, choose the instance and period to be analyzed.

       3.      Choose This graphic is explained in the accompanying text Analysis Views → This graphic is explained in the accompanying text Response Time Distribution.

       4.      The system displays the usual output area, in which the requested distribution of the workload is displayed.

Result

The output area contains three tab pages with the following characteristics:

Tab Page

Description

Steps

The system displays the absolute number of transaction steps in the individual response time categories, broken down by task type.

Percentage

The system displays the proportion of transaction steps (as a percentage) in the individual response time categories, broken down by task type.

Percentage (Cumulated)

The system displays the proportion of transaction steps (as a percentage) with a response time between 0s and the upper limit of the individual response time categories, broken down by task type.
