Option Description
Amount of CPU demand peaks
above
Considers the virtual machine undersized when the following conditions
are met:
n
CPU demand is more than the percentage of its allocated capacity as
indicated in this field.
n
Duration of CPU activity under this threshold compared to total time
evaluated meets the % undersized threshold.
Amount of memory demand peaks
above
Considers the virtual machine undersized when the following conditions
are met:
n
Memory use is more than the percentage of its allocated capacity as
indicated in this field.
n
Duration of memory activity under this threshold compared to total
time evaluated meets the % undersized threshold.
is more than number% for
Sets the amount of use in the entire environment defined by the %
undersized threshold and the time range to analyze.
Any number hour period
Sets the time range to analyze as a period of hours.
Entire range
Sets the time range to analyze as the range defined in the Manage Display
Settings section of the Configuration dialog box.
5 Click OK or Finish to save your settings, or select another option to configure.
6 Click Done to close the Configuration dialog box.
The criteria for oversized and undersized virtual machines are reconfigured.
Example: Oversized and Undersized Virtual Machine Settings
The following examples show how some of the settings are used.
% oversized threshold
If the threshold is 70 percent, a virtual machine that has an average capacity
use of 60 percent is considered oversized. A virtual machine with an average
capacity use of 75 percent is not oversized.
% undersized threshold
If the threshold is 10 percent, a virtual machine that has an average capacity
use of 8 percent is considered undersized. A virtual machine with an average
capacity use of 45 percent is not undersized.
Modify the Criteria for Underused and Stressed Capacity
Underused and stressed capacity settings help you identify the load on clusters and hosts before you deploy
virtual machines.
An administrator can modify any policy in vCenter Operations Manager at any time. The changes that the
administrator applies affect all users. Therefore, the administrator must notify the users who are working
with vCenter Operations Manager about any new settings that are applied to the policies.
Prerequisites
Verify that you are logged in to a vSphere Client as an administrator, and vCenter Operations Manager is
open.
Procedure
1 Click the Configuration link on the main vCenter Operations Manager page.
