5. Click the OK button to save and apply a new definition for global forecasting.
TIP:
Undoing changes to the global forecast model
If you change your mind about values while editing this screen, use the Revert button to replace
newly set values with the values that were there when you started.
The Revert button does not return default values, so if you have edited the global forecast
values once before, and then decide that you prefer the default values, you will have to set
the values to “0” (zero) for each resource and click OK to have the original default values in
operation.
Accessing the forecast model for a workload or system
When the resource utilization of an individual workload or system is expected to differ from that
predicted by the global forecast model, a workload- or system-specific forecast model can be
created.
Forecasting for workloads or systems is done from within a profile viewer associated with the
workload or system. See “Using the Profile Viewer” (page 46) for information on how to access
the viewer from the Optimize menu or from a scenario.
IMPORTANT: The forecast model for a system is not inherited by any monitored workloads. If a
system with monitored workloads is included in a scenario, the forecast model will not be used
within the scenario.
Prerequisites
• You must be logged in to Matrix Operating Environment. (See “Accessing Capacity Advisor”
(page 37).)
• You must have sufficient authorization to define the forecast model for a workload or a system.
Defining the forecast model for a workload or system
The following procedure assumes that a profile viewer is open (see “Using the Profile Viewer”
(page 46).)
1. If you are not on the Visualization screen, from the top menu, select Tools→HP Matrix OE
visualization....
The Visualization tab screen is displayed.
2. To define the forecast model for a system, start on the Visualization tab.•
• To define the forecast model for a workload, click the Workload tab.
The Workload tab opens, displaying the licensed workloads.
3. Open a profile viewer by clicking a utilization meter for a particular system on the Visualization
tab or by clicking a utilization link for a particular workload on the Workload tab.
The Profile Viewer screen is displayed for the system or workload.
4. Click the Edit Forecast Model... link on the profile viewer.
The Forecast Editor: Workload Forecast Model screen displays.
5. • To define the forecast model, follow the procedure Defining a forecast model.
• To disable the forecast model, follow the procedure Disabling a forecast model
