Enter any of the following parameters:

History Descriptor

Enter the name of the history file descriptor. The descriptor name is limited to 20 characters.

Data Reduction Scheme

By default, the granularity value is monthly. Click and hold the pointer on monthly and the granularity pop-up menu displays a list of value options. Release the mouse button when the cursor is on your choice. The pop-up menu disappears and your selection is displayed.

By default, the periodicity value is None. Click and hold the pointer on the current value and the periodicity pop-up menu displays a list of value options. Release the mouse button when the cursor is on your choice. The pop-up menu disappears and your selection is displayed.

By default, the interval value, the time period over which the Performance Manager averages daily data records into a single history data record, is 60 minutes. To display valid entries, click the up or down arrow. When your selection is displayed, click the value. Your choice will be highlighted.

Archive Schedule

A 24-hour clock is displayed. A bar on the right side of the clock lets you scroll to each day of the week. By default, archiving is set on for 24 hours a day, seven days a week, including holidays.

To set the clock:

  1. Set or reset the square toggle button above the clock to turn archiving on or off for an entire day.
  2. To turn archiving off for a specific hour, point to the hour on the clock and click MB1. Holding down MB1 and dragging the pointer around the clock will turn off archiving for a series of contiguous hours.
  3. Drag the slider on the scroll bar to display the archiving schedule for each day of the week or click the up or down stepping arrows.

To duplicate a day's schedule

  1. Press and hold MB3 inside the clock. A pop-up menu is displayed. Release on the Cut menu item.
  2. Scroll to another day and press MB3 inside the clock. Release on the Paste menu item. The clock displays the copied schedule.
Workload Classification

By default, Performance Manager stores process data in the history file summarized by workload families. To save modeling data in the history file, click the model data (unlimited) button. When model data is enabled, no workload families can be selected and raw process data will be preserved. Specific classification can then be done when the archived data is processed.

If you choose Classify by Families without specifying the workload families, process data will be summarized into four records representing interactive, batch, network, and detached processing. All other process data will be lost such as process data based on image name, account name, and so on.

Workload Families Excluded

The Workload Families Excluded list box contains a list of workload families. To add a workload family to a history file definition, click a workload family name and click the transfer button.

To add multiple workload families, click all their names contained in the Excluded list box. Then click the transfer button.

Workload Families Included

The Workload Families Included list box contains a list of workload family names. These names specify the workload families that define the new history descriptor. To remove an entry from the Included list box, click the name and click the transfer button.
