Displaying a Business Transaction Analysis

Use

You can use the workload monitor to display the business transaction analysis. The analysis calculates the system resource usage of individual transactions and returns the most detailed analysis of a transaction and the dialog steps. The selection criteria include user, transaction, program, task type, start date, and start time.

The business transaction analysis uses the statistics files STAT and ASTAT (dialog step statistics and application statistics) in the file system of the relevant instances as its data sources. This data basis allows more detailed analysis than the other analysis views of the workload monitors, which use the aggregated data from the workload collector database as their data source. Note that you can only execute the business transaction analysis for the period for which the statistics files are retained (by default, 48 hours).

Procedure

Call transaction ST03 to start the Workload Monitor.
Choose Detailed Analysis → Business Transaction Analysis.
The Select Statistical Records dialog screen appears. You can make the following settings here:
Choose one of the following display modes in the Display Mode group box:
- Show all statistics records, sorted by start time
  The system displays a chronological list of dialog steps with their resource usage (this corresponds to the individual statistics records and the transaction statistics).
- Show all records, grouped by business transaction
  The system displays a list of dialog steps with their resource usage, grouped by transactions. The list contains the individual dialog steps of a transaction.
- Show business transaction sums
  The system displays a list with totals of workload data for every transaction. This variant is used most frequently.
  
  Note
  
  In the first two cases - if you have restricted the data to certain users or transactions, and so on - the system reads only the corresponding records. In the third case, the system reads all records, but displays only the records that match the selection criteria. You should consider this if you switch to a different display mode by choosing Disp. Mode.
Use filters in the Filter Parameter group box to define which statistics data you want to display.

In the Tools group box, choose one of the following commands:
- Include statistics from memory
  The statistics data is buffered first, before it is read into the STAD file. 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.
- Include application statistics
  Choose this check box to display application statistics too.
- Server selection
  This pushbutton restricts the analysis to certain instances in the system. Select the desired instances.
- Additional options
  You can set the wait time for the Remote Function Call (RFC), maximum runtime of the analysis, and the time period to be used for the analysis.
