Statistics 

Statistics give you an overview of the performance of your system. You can display statistics about the system load in the following ways:

·        Workload Monitor

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.

·        Global Workload Monitor

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.

·        Functional Trace

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, the functional trace enables you to monitor actions for a particular business process across multiple systems. You can also display traces such as the SQL trace or DSR trace from the functional trace.
