 Displaying the Workload History and Workload Distribution in the Workload MonitorLocate this document in the navigation structure

Purpose

The workload monitor is conceived in such a way that the workload for a particular instance that you can display the workload for a specific instance and a particular period of time, and compare the load for these circumstances caused by various transactions, users, RFC destinations, external systems, and so on.

Some questions cannot, however, be answered with these display conditions, such as the development of the workload over time (Load History) or the distribution of the workload for different instances (Instance Comparison).

Process Flow

Workload History

Use the Load History to check how the workload develops for a selected task type and a selected instance.

  1. Start the Workload Monitor by calling transaction ST03.
  2. Expand  Load History and Distribution →  Load History.
  3. The system displays a list of the available instances and optionally the TOTAL entry for all instances. Choose the desired instance by double-clicking it.
  4. The Workload: Compare all The Workload: Compare all periods for one instance screen appears. The system displays a list of workloads for the selected instance at different times. You have the following options on this screen:
    • Changing the Aggregates

      You can display the workload for different Days, Weeks, or Months for the selected instance. Choose the corresponding button to do this.

    • Changing the Output View

      You can use the output view to select which workload data is displayed on the screen. You have the following options:

      Output View

      Meaning

      Mean Values

      Selected workload values from the Workload Overview analysis view, for the selected task type in each case

      Total Values

      DB Access

      Response Time Distribution

      See Displaying the Response Time Distribution

      Measurement Interval

      Time stamp of the first and last statistics records during the selected period
    • Sorting the Output

      You can sort the output by any column. To do this, select the desired column and choose the Sort button.

    • Changing the Task Type

      You can specify the task type for which workload is to be displayed. To do this, choose Other Task Type, and select the desired type.

Instance Comparison

In the Load History, you displayed the workload data for an instance for different times; in the Instance Comparison, you display the workload data for different instances for one period.

  1. Start the Workload Monitor by calling transaction ST03.
  2. Expand  Load History and Distribution and then double-click  Instance Comparison.
  3. The screen Workload:  Compare all instances for one period appears.The system displays a list of all instances and their workloads during a particular period. You can use the following commands:
    • Changing the Output View

      You can use the output view to select which workload data is displayed on the screen. The same output views are available as in the Load History.

    • Sorting the Output

      You can sort the output by any column. To do this, select the desired column and choose the Sort button.

    • Changing the Task Type

      You can specify the task type for which workload is to be displayed. To do this, choose Other Task Type, and select the desired type.

    • Changing the Period

      You can determine the time period for which workload data is to be displayed. To do this, choose the Previous Period and Next Period buttons (you can select a period of Days, Weeks, and Months by choosing Edit → Choose Period Type).

The Load History and Instance Comparison display only data that you can select using the Analysis Views. The difference is that in the Load History, you can compare workloads directly in one list, which would otherwise always be in different output tables due to the structure of the workload monitor.

It is therefore a summary - the system displays the same data in a different format.

Users per Instance

Another comparison that you can display for workload distribution is the number of users per instance.
