Table 6 Forecast model attributes
Description Field
Descriptive text of this model for your use. Description
Defines the set of historical data on which the forecast will be based. If the
selected set contains invalid data at the end of the period, the forecast will
consider the last valid data to be the end of the period. The forecast data
range can be specified as:
•
A fixed interval ending or beginning on a specific date
• A float interval ending after a specified time period
•
An absolute interval between two selected dates
Forecast Data Range Selection
When this feature is checked, automatic adjustment of the specified range
is enabled. If the box is checked, and the selected scenario does not have
existing data in the specified range, then the range is shifted to use the
existing data. If the existing data range is shorter than the specified forecast
range, then the forecast range is shortened to fit the available data. Default:
on (checked)
Removing the check mark from the box prevents a forecast from being
generated until a data range is specified that contains an interval of collected
data sufficient to fill the forecast period.
Example: Assume that you want to view activity one week (7 days) into the
future using the most recent week of data. However, in this particular week,
only four days of data were collected. With this featured turned on, the
future will be tiled with repetitions of the four days of data until the forecast
interval is filled.
Automatically adjust the specified range
to use existing data
Specified in percent for each utilization resource measured (CPU, memory,
network I/O, and disk I/O).
Use positive values for increasing utilization, negative values for decreasing
utilization, or zero to indicate no change. Default: zero (0)
Annual project growth rates in force for a workload within a scenario are
displayed in the Scenario Workloads Resource Utilization table on the Edit
Scenario Workload tab.
