## 6.3.3.4.3.2  Defining a Capture Profile for Sizing
With the Capture Request Statistics app, you can capture request statistics to find out which activities are running in your ABAP system. For sizing, you can define a capture profile that records defined activities of a business user or business process.
## Prerequisites
You've defined one or multiple test cases to measure the workload of sizing-relevant business processes (see Defining Test Cases for Sizing [page 3108]).
## Context
With the definition and activation of a capture profile, you can capture system activities. Requests are recorded with technical information, such as response time, program name, or CPU time. The request statistics serve as input for ABAP system sizing using the Perform System Sizing app (see Performing System Sizing [page 3114]).

##  Note
In this documentation, the assumption is that workload for a particular business process is measured by capturing the request statistics generated by the activities of a business user who acts as a tester. With such a measurement approach, you define the profile that contains the technical user name of the tester and a time period reserved for testing.
## Procedure
1. In the SAP Fiori launchpad of the ABAP environment, under Technical Monitoring , choose the Capture Request Statistics tile.
2. Choose Create .
3. Enter the following data:
| Field          | What to enter                                                                                                                                                |
|----------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Profile ID     | Enter a short, meaningful name for your profile. Don't use the prefix SAP_ because this prefix is reserved for profiles predefined by SAP.                   |
| Description    | If needed, you can enter a longer description of your pro- file.                                                                                             |
| Start/End Time | The start and end time specify when request statistics were captured by the app. These fields are automatically filled after you have activated the profile. |
| Field             | What to enter                                                                                                                                                                                                                                                                 |
|-------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Retention Time    | Select how long you want to keep the captured request statistics stored in the system, for example, 14 days.                                                                                                                                                                  |
| Record Limit      | Enter the maximum number of records that you want the system to capture per minute, for example, 1,000 records. The record limit prevents that too much database mem- ory is consumed by captured request statistics. The maxi- mumpossible record limit per minute is 1,000. |
| Sampling Rate     | Enter a sampling rate, which is the probability of capturing one single ABAP statistics record in percent.                                                                                                                                                                    |
| Target User Group | Choose one of the target groups starting with Customer .                                                                                                                                                                                                                      |
| Profile Type      | This field is automatically populated by the system. Only static profile types (with fixed values) are possible.                                                                                                                                                              |
| Profile Owner     | The profile owner is automatically set to Customer when you create a new profile.                                                                                                                                                                                             |
4. Choose Create .
The profile has been created, but is still inactive and has no filter conditions yet.
5. To define the filter conditions under which request statistics are captured, choose Create .
6. With Field ID , Operator , High , and Low , you can select a filter condition that determines what kind of data is captured.
For example, if you want to capture all request statistics relating to your tester, select User ID as field ID, include equal to as operator and the technical user name of the tester.
7. Choose Create .
8. To enable capturing request statistics using the profile, choose Activate .
If you use the capturing of request statistics to measure sizing, enter the planned start and end time of your test case.
