To enable the forecast model, follow the procedure Enabling a forecast model .
Defining a forecast model
Once you have accessed a forecast model, use the following procedure to define it.
For descriptions of each of the fields noted in this procedure, see the screen description for the
model with which you are working in the Capacity Advisor online help. See
“The forecast model
hierarchy” (page 34) for a list of the model screen descriptions.
1. Provide a brief description of the forecast model in the Description field
2. Specify an appropriate range of data to base the forecast on in the Forecast Data Range
Selection fields.
3. Provide Annual Projected Growth Rates for each of the utilization resources (CPU, memory,
network I/O, disk I/O). You may want to use trend data derived from analyzing historical
data to help you estimate future growth (see
“Forecasting growth” (page 34) ).

Generating forecasts
Once you have defined one or more forecast models, you can view the results of the forecast
models two ways:
•
For a quick view, “Viewing forecast data in a profile viewer”
•
For a more thorough report, “Viewing forecast data in a utilization report” (page 65)
Viewing forecast data in a profile viewer
A profile viewer provides a quick view of resource utilization for a system, complex, or workload.
Once the profile viewer is posted, you can view the forecast by extending the date range into the
future.
