Workload Monitor


The workload monitor (transaction ST03N) is intended for use by EarlyWatch and GoingLive teams. The workload monitor was reworked as part of the EnjoySAP initiative, so that the Workload Overview is now simpler and more intuitive.

You use the workload monitor to analyze statistical data from the SAP kernel. When analyzing the performance of a system, you should normally start by analyzing the workload statistics. For example, you can display the totals for all instances and the compare the performances of individual instances over specific periods of time. You can quickly determine the source of possible performance problems using the large number of analysis views and the determined data.

You can use the workload monitor to display the:

  • Number of configured instances for each SAP system
  • Number of users working on the different instances
  • Distribution of response times
  • Distribution of workload by transaction steps, transactions, packages, subapplications, and applications
  • Transactions with the highest response time and database time
  • Memory usage for each transaction or each user per dialog step
  • Workload through RFC, listed by transactions, function modules and destinations
  • Number and volume of spool requests
  • Statistics about response time distributeion, with or without the GUI time
  • Optional: Table accesses
  • Workload and transactions used listed by users, payroll number, and client
  • Workload generated by requests from external systems

For all of this data:

  • You can display the data for a particular instance (not only the one to which your logged on) or optionally totalled for all instances.
  • Depending on your user mode, you can choose the time period for which you want to display the data between day, week and month (or determine the length of time yourself using the Last Minutes’ Load function).
  • For most analysis views, you can display all or only certain task types.


The workload monitor completely replaces the old ST03 transaction.


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

  • Select the user mode
  • Select the time period for which you want to display the workload
  • Select various functions and analysis views (which data you want to display).

The system then displays the result on the right of the screen in a standardized ALV Grid Control. With it, you can :
