 Workload MonitorLocate this document in the navigation structure


You can use the workload monitor (transaction ST03) to analyze statistical data for the ABAP kernel. If you are analyzing the performance of a system, you should normally start with the workload overview. You can also display the total values for all instances, and compare the performance of particular instances over a period of time. A wide range of analysis views and data helps you to find the source of performance problems quickly and easily.

You can use the workload monitor to display the following, among other things:

  • Number of instances configured for your system
  • Number of users working on the different instances
  • Response time distribution
  • Distribution of workload by transaction steps, transactions, packages, subapplications, and applications
  • Transactions with the largest response times and database time
  • Memory usage for each transaction or each user per dialog step
  • Workload caused by RFC, broken down by transactions, function modules, and destinations
  • Number and volume of spool requests
  • Statistics about response time distribution, with or without the GUI time
  • Optional: Table accesses
  • Workload and transactions used by users, broken down by users, accounting numbers, and clients
  • Workload generated by requests from external systems

The following applies to all of this data:

  • You can display data for any instance (not only the instance that you are logged onto), or optionally summarized for all instances.
  • Depending on the user mode, you can choose the period for which you want to display data between day, week, and month, or specify the Last Minutes' Load as you require.
  • For most analysis views, you can display all or only certain task types.

The workload monitor has an interface that is divided into two parts. Use the tree structures on the left to make the following settings:

  • Select the user mode
  • Select the period for which you want to display the workload
  • Select different functions and analysis views (which data do you want to display?)

The system then displays the result on the right in a standardized ALV Grid Control. You can use this to:

  • Adjust the layout of the data output
  • Find any information using sort and filter functions
  • Save user-specific views
  • Display statistics graphically
