2.
Choose a time frame to use in tiling the data into the future (default: fixed interval).
The time interval (date range) field adjusts according to your time frame selection.
3.
Select the date range for defining the period of data collection to use as the basis for the
forecast.
a.
For a fixed interval: select the calendar interval, Beginning or Ending, and the date
(MM-DD-YYYY)
b.
For a ranged interval: select the beginning and ending dates and times.
c.
For a float interval: select the calendar interval, Beginning or Ending, and general
date indicator (default: Last Full Day)
4.
Provide Annual Projected Growth Rates for each resource: CPU, Memory, Network I/O, and
Disk I/O. Use positive values for increasing utilization, negative values for decreasing
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”

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
.)(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
