 Selecting Data for the Functional TraceLocate this document in the navigation structure

Use

You can use data selection to select the data to be analyzed. With this function, you filter which statistics records (raw records) are to be displayed in the analysis view of the functional trace (transaction STATTRACE).

Prerequisites

You have defined the systems from which statistics records are to be analyzed in the system selection.

Procedure

Follow the procedure below to select data for the functional trace:

  1. Start the functional trace (transaction STATTRACE).
  2. Choose Data Selection in the left subwindow of the initial screen.

    You can show and hide the left subwindow by choosing Full Screen On/Off.

  3. To determine the analysis interval, specify start date, start time, and the read period(in minutes).
  4. You can optionally restrict the individual records to be displayed using the following specifications:
    • Initial system
    • Initial user
    • Initial action
    • Transaction ID

    With these input parameters, the system filters using the passport, which contains values for these parameters. If statistics records are written beyond component boundaries, the passport is sent together with the communication between the components. You can use the passport to determine which steps belong to an action, even if they were performed on different components.

    The initial system is the starting system of an action that runs over multiple components. The action that is started in this system is the initial action that is started by an initial user and for which the transaction ID is assigned. The transaction ID is the GUID from the passport that identifies all dialog steps.

  5. If desired, you can choose the options Read Additional Records and No ADM Records:
    • If you determine that the delivered data is not sufficient for your requirements and want to fill out a new time window, activate Read Additional Records, so that the newly collected statistics records are added to the statistics records that have already been collected. If you do not activate this option, the previously read statistics records are deleted, and the system displays only the statistics from the new query.
    • The No ADM records option is activated by default; that is, the ADM statistics records are hidden. This is useful, since there is a large number of ADM statistics records and this can therefore affect the performance. 
  6. Confirm your selection.
Result

The system displays the statistics records with their general information. You have the following options for a new data selection:

  • Fill out a new time window using New Selection
  • Choose 1 Time Unit Previously to display the statistics records that were written one time unit earlier, where the time unit corresponds to the read period that you used for the previous data selection
  • Choose 1/2 Time Unit Previously to display the statistics records that were written half a time unit earlier
  • Choose 1/2 Time Unit Later to display the statistics records that were written half a time unit later
  • Choose 1 Time Unit Later to display the statistics records that were written one time unit later

For more information about individual statistics records, choose the relevant record to display the corresponding statistics record in the Detail View.
