The tasks that you can perform are:

See Also Performing Tasks from the Menu Bar Performing Tasks in the Configuration Panel

20.4.1 Defining Data

Defining data is the first step in workload characterization. You can specify parameters that will be used to group processes with similar characteristics into classes and subclasses.

To define data, click on the Define Data push button.

The Define Classification dialog box is displayed. You must define your workload classes and subclasses before reading in merged data.

See Also Reading Data

20.4.2 Reading Data

To read data, click on the Read Data push button.

The Workload Data Import dialog box is displayed.

Follow the steps for selecting domains and reading in different types of data. After reading in data, you can optionally modify the workload before you model.

20.4.3 Modifying Data

To modify the workload before you model, click on the Modify push button. The Workload What-If Editing dialog box is displayed. You can:

20.4.4 Building and Validating a Model

To build a baseline model and compare the modeled performance statistics with the measured performance statistics, click on the Build Model push button in the Workload Analysis window.

A message is displayed in the Session Messages window indicating model completion and the time it took to build the model.

20.4.5 Generating Reports

To generate reports:

  1. Click on one of the Report push buttons, Table or Graph.

    The Table or Graph Report Writer window is displayed.

  2. Follow the steps for using the Table or Graph Report Writer window.

20.5 Main Push Button

Use the Main push button to display the Main window. The Main window displays push buttons that shows a flow diagram of the steps in the capacity planning methodology.
