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

4.4.1 Collecting Data

You can collect Event Monitor data (OpenVMS) or system accounting plus snapshot data (UNIX). Event Monitor data includes interactive think and response times per process and disk use per process. The Event Monitor data collector records process creation and deletion and image activation and deactivation.

To collect Event Monitor data (OpenVMS) or system accounting data (UNIX)

  1. Click on the Collect Data push button in the Main window.

    or

  2. Choose Data Collector from the Control menu.

    The Data Collector window is displayed.

  3. Follow the steps for using the Data Collector window.

4.4.2 Integrating Data

The Data Integrator processes measured, sampled, and event data collected by the data collectors. It produces a system resource use file and merged data file (.MERG or .merg) that can be used during workload characterization.

To integrate the collected data:

  1. Click on the Integrate Data push button in the Main window.

    or

  2. Choose Data Integrator from the Control menu.

    The Data Integrator window is displayed.

  3. Follow the steps for using the Data Integrator window.

4.4.3 Drawing a Configuration

To draw a configuration:

  1. Click on the Draw Configuration push button in the Main window.

    or

  2. Choose Draw from the Configuration menu.

    The View Library window is displayed.

  3. Follow the steps for using the View Library window.

4.4.4 Characterizing the Workload

Characterizing a workload reduces the number of process profiles making up the workload into classes. It also builds and validates a base model.

To classify and model data:

  1. Click on the Workload Analysis push button in the Main window.

    or

  2. Choose Workload Analysis from the Control menu.

    The Workload Analysis window is displayed.

  3. Follow the steps for using the Workload Analysis window.

4.4.5 Performing What-If Analyses

You can perform what-if analyses to predict performance and create a saturation analysis.

To perform a what-if analysis:

  1. Click on the What-Ifs push button in the Main window.

    or

  2. Choose Performance Model from the Control menu.

    The Model window is displayed.

  3. Follow the steps for using the Model window.

4.4.6 Reporting

To obtain the various types of reports available:

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

    or

  2. Choose Report Writer from the Control menu, and select Table or Graph.

    The Table Report Writer window or Graph Report Writer window is displayed.

  3. Follow the steps for using the Table or Graph Report window.

4.5 Collect Data Push Button

Use the Collect Data push button to display the Data Collector window. You can specify the types of data to collect and the time period of collection. You can also start the data collector.

See Also Collecting Data

4.6 Integrate Data Push Button

Use the Integrate Data push button to display the Data Integration window. You can specify the data files for integration and the time period for integration. You can also start the Data Integrator.

See Also Integrating Data

4.7 Draw Configuration Push Button

Use the Draw Configuration push button to display the View Library window. Using the icons in this window, you can graphically configure a new system or add to or remove components from a displayed configuration in the Network/System Configuration panel.

See Also Drawing a Configuration

4.8 Workload Analysis Push Button

Use the Workload Analysis push button to display the Workload Analysis window. You can characterize a workload and produce and validate a baseline model.

See Also Characterizing the Workload

4.9 What-Ifs Push Button

Use the What-Ifs push button to display the Model window. You can modify system configurations and edit workload parameters to perform what-if analyses. You can predict performance and perform a saturation analysis.
