The workload monitor (Transaction ST03N) is an expert tool that is intended for use by EarlyWatch and GoingLive teams. Release 4.6C of the workload monitor has been reworked as part of the EnjoySAP initiative, enabling you to monitor and evaluate workload statistics more easily and intuitively than before.

You use the workload monitor to analyze statistical data from the R/3 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 compare the performance of individual instances over specific periods of time.

You can use the workload monitor to display the:

• Number of configured instances for each SAP System
• Data for all application instances, not just the one you have logged on to
• Transactions used and the users that call them
• Number of users working on the different instances
• Performance history for recent periods for all instances
• Response time distribution and resource consumption for any application server
• Application server workload for today or for a recent period.

Until all of the functions have been replaced, you will still need to use Transaction ST03 to display hitlists, aggregation in transactions and to access detailed information on a transaction by double-clicking on an individual profile (and other profiles such as memory, RFC, user, table and client).

The workload monitor has a new interface that is divided into two parts. Use the tree structures on the left of the screen to choose the user mode and profiles that you require. The system then displays the results on the right.

The new workload monitor has the following features:

• Standardized ABAP ALV grid controls, enabling you to search for and filter the information you require
• User modes
• Cross-client information (information on application servers other than the one you have logged on to)
• Save user-specific views
• Graphics of the statistics for each task type
