Selecting the Statistics Records

Use

If you want to display ABAP Statistics Records for performance analysis, you can use transaction STADWD for this purpose. First, define conditions and grouping rules for the main statistics records that you want to display. This section describes these settings.

Selection Criterion	Description
Display Mode	You can define here the criteria by which the main statistics records to be displayed are to be formatted and sorted. More information: Selecting the Display Mode for the Display of Statistics Records.
Read Interval	You can define a time frame here for which you want to display statistics records. Note The analyzed time period can be larger than the defined interval defined, since the system analyzes complete transactions as far as possible. However, it is not always possible to perform a complete analysis for long-running transactions. Since the analysis is time-consuming, you should use as short an interval as possible (around 10 minutes).
Set Filter	You can define conditions here that the statistics records to be displayed must fulfill. Note that the following filters are intended as a lower limit, that is, that all statistics records are displayed for which the collected values are above the defined filter settings: Response Time (ms) DB Query Time (ms) CPU Time (ms) Data Received (Bytes) Number of DB Changes
EPP Filter Options	This area is only displayed if you have selected the display mode EPP Filters (more information: Selecting the Display Mode for Displaying Statistics).
Server Selection	You can define the instances for which you want to display statistics records here. By default, statistics records are displayed for all instances of the system.
Further Options	Take Statistics from Memory into Account The statistics data is buffered first, before it is saved in the file system. This option forces the buffer to write the data to a file before the analysis is performed. This ensures that you can analyze the most recent transactions. Load Application Statistics Records Choose this check box to display application statistics too. The application statistics are activated using special calls within the ABAP coding, which allows the system to collect statistics for individual parts of an application. While statistics records always contain a complete dialog step by default, you can use the application statistics to analyze the resources used by an individual function within a dialog step (such as price determination). In some cases, the application statistics can therefore replace an SQL trace.
