Statistics
Statistics give you an overview of the performance of your system. You can use the statistics to display the workload. There are the following important statistics displays:
-
The workload monitor displays statistical data from the local ABAP system. The workload overview enables you to analyze the performance of a system. 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.
-
The global workload monitor displays statistics for entire landscapes, including statistics for the non-ABAP components J2EE Engine, BC, and ITS. For example, in this monitor you can display the load data created when external components are started.
-
Analyzing Individual ABAP Statistics Records
Use ABAP statistics records to find out which activities are running in your system. This is a log of system activities that is implemented in the ABAP kernel. Every dialog step is logged and recorded with technical information, such as response time, transaction code, or CPU time. Unlike the workload monitor, the individual records, not the aggregates, are displayed.
-
Whereas the global workload monitor shows only aggregated data, you can use the functional trace to display raw statistical data (single records) from both ABAP systems and the non-ABAP systems J2EE Engine, BC, and ITS in complex system landscapes. The functional trace uses RFC (or agents in non-ABAP systems) to get the raw data, which means that the information has a higher level of detail. For example, you can use the functional trace to trace actions that belong to a business process across system boundaries. You can also display traces such as the SQL trace or DSR trace from the functional trace.
