Forecast Window Panes
Chapter 7 describes the basic layout of the Forecast program window panes:

Main Program Window Panes (Unvalidated)

The Main Program window enables you to review data on the host system for accuracy before the model is validated. Although the window structure is the same, some of the sub windows in the Main Program window function differently when viewing an unvalidated model.


Figure 7.1 Main Program window (unvalidated model)
The Main Program window is divided into three panes:
  • The file manager pane.
  • The global unvalidated centers pane.
  • The global unvalidated workloads pane.
  • File Manager Pane

    The file manager pane contains an outlined view of the model. It provides a quick and easy way to access and change information about the model.


    Figure 7.2 Main Program window: file manager
    From the file manager, you can:
  • Expand or collapse the outline by clicking the Plus (+) or Minus (-) icons.
  • Change the view in the right-hand side of the Main Program window by clicking the icons in the file manager pane:
  • Click the Centers icon to change the right part of the window to and expanded view of the global unvalidated centers pane.
  • Click the Workloads icon to change the right part of the window to and expanded view of the global unvalidated workloads pane.
  • Edit the model name by double-clicking the Model icon.
  • Edit the individual resources (CPU or disk drive) or workload groups by double-clicking the appropriate icon in the file manager pane.
  • Global Unvalidated Centers Pane

    The global unvalidated centers pane in the Main Program window displays the results for each CPU and disk drive in the model.


    Figure 7.3 Main Program window: global unvalidated centers pane
    Global results are listed by:
  • Resource Name
  • Resource Type
  • Access Time
  • IO/sec:
  • Actual
  • Model
  • Variation between the model and the actual data as a percentage
  • Average Queue Length:
  • Actual
  • Model
  • Variation between the model and the actual data as a percentage
  • Global Unvalidated Workload Pane

    The global unvalidated workloads pane displays the results for each CPU and disk drive in the model.
    Global results are listed by:
  • Number
  • The number of each workload group.
  • Priority
  • Which queue the workload group is in.
  • Type
  • Whether the workload group is a JOB or TRANSACTION.
  • Number of users
  • The number of users who were on the system during the sampling interval.
  • Workload
  • The name given to the workload groups.
  • Description
  • If the workload group was given a description beyond a name and definition.
  • Transactions/Hour:
  • Actual
  • Model
  • Variation between the model and the actual data as a percentage
  • Response Time:
  • Actual
  • Model
  • Variation between the model and the actual data as a percentage
  • CPU Utilization:
  • Actual
  • Model
  • To view detailed information on a single resource in the model, click the associated icon in the file manager pane.

    Main Program Window Panes (Validated)

    Once the model is validated, the data fields in the global validated centers pane and the global validated each workload group pane change to reflect the validated model as shown in Figure 7.4 and Figure 7.5, respectively.

    Global Validated Centers Pane

    The global validated centers pane displays the modeled data for each CPU and disk drive in the model.


    Figure 7.4 Main Program window (validated model): global centers pane
    To view detailed information on a single resource in the model, click on the associated icon in the file manager pane.
    Results are listed by:
  • Resource Name - name of the hardware device as seen by the operating system.
  • Resource Type - identification name of the hardware.
  • Access Time - average access time for all processes.
  • Utilization as a percent of total.
  • Average Queue Length for the validated model.
  • IO/sec for the validated model.
  • Global Validated Workload Pane

    The global validated workload pane in the Main Program window displays the modeled data for each workload group included in the model (see Figure 7.5).


    Figure 7.5 Main Program window (validated model): global workloads pane
    To view detailed information about a particular workload in the model, click the associated icon in the file manager pane.
    Results are listed by (see "Global Unvalidated Workload Pane" for descriptions):
  • Number
  • Priority
  • Type
  • Number of Users
  • Workload Name
  • Description
  • Transactions/Hour for the validated model.
  • Response Time for the validated model
  • CPU Utilization for the validated model
