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 reference. See
“The
forecast model hierarchy” (page 33) 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 33) ).
4. Click the OK button.
Disabling a forecast model
While it is not possible to delete a forecast model, forecast models at all levels below the global
forecast model can be disabled by accessing the appropriate forecast model and using the
following procedure.
1.
Click the Disable radio button.
2. Click the OK button.
Enabling a forecast model
If you have previously disabled a forecast model, you can re-enable it by accessing the appropriate
forecast model and using the following procedure.
1. Click the Enable radio button.
2. Click the OK button.
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 83)
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.
Prerequisites:
• You must be in a profile viewer. (See “Using the Profile Viewer” (page 65) .)
• Change the Time Frame and/or Interval and/or Beginning and/or Ending for the profile
to include future dates and/or times. If necessary, click the Refresh button.
The graph will be updated. Historical utilization data will be plotted on a white background
and forecast data will be plotted on a light blue background.
Viewing forecast data in a utilization report
Use the procedure specified in “Creating an historic utilization report” (page 70) and specify
Ending (and possibly Beginning) times under Date Selection to include future times.
Historical utilization data will be plotted on a white background and forecast data will be plotted
on a light blue background.
