Displaying Application Statistics 

Use

Application statistics enable you to analyze resource consumption in more detail than using the workload statistics.

Using special calls within the ABAP code, the system collects statistics for individual parts of an application. Whereas the workload statistics analyze a complete dialog step, application statistics analyze the resources that an individual function consumes within a dialog step (such as price determination). In some cases, the application statistics can replace an SQL trace.

The statistics collected by the application statistics are generally the same as the standard workload statistics (response time and so on).

Prerequisites

To use the application statistics, special function calls must be implemented in the application programs. Application statistics cannot be collected without these calls. In addition, the following profile parameters must be set as indicated: stat/as_level=1 and stat/as_collect=2. The application statistics collector ( RSSTAT87 ) must be scheduled using table TCOLL . You must also activate the individual components of the application statistics by calling Transaction ST03N and choosing Collector & Perf. Database ® Parameter & Reorg. ® Statistics records ® Application statistics.

Procedure

  1. Call the workload monitor (Transaction ST03N).
  2. Specify the application servers and the time period that you want to analyze.
  3. From the Analysis views, choose Application statistics.

If no application statistics are available for the given instance / time period, the system does not display the icon for the application statistics.
