utilization, and zero for no change). The default is 1% projected annual growth for every
resource.
TIP: You can estimate projected annual growth by including trend calculations in utilization
reports derived by analyzing historical data. (See “Determining trends in Capacity Advisor”
(page 31) and “The report wizard” (page 69) .)
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 65) for information on how to access
the viewer from the HP SIM 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 Insight Dynamics. (See “Accessing Capacity Advisor” (page 53) .)
• 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 65) .)
1. If you are not on the Virtualization Manager screen, from the top menu, select
Tools
→Virtualization Manager....
The Virtualization Manager 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.
