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.
2 Create a new policy or open an existing policy for editing.
Option Description
To create a new policy
In the Manage Policies pane, click the Create Policy icon .
To modify an existing policy
In the Manage Policies pane, select the policy that you want to associate to
groups and click the Edit Policy icon .
3 Click 3c Usage calculation to change the settings for work week calculation and allocation overcommit
ratios.
4 Set the Usage Work Week to a continual array of sampling or specific times to sample.
Option Description
All hours on all days
Average capacity use is calculated based on inventory and performance
data collected during all 24 hours of each day throughout the business
week.
Specific hours and days
Average capacity use is calculated based on inventory and performance
data collected during business hours that you define for each day
throughout the business week.
5 Enter Allocation Overcommit Ratios
An allocation model considers allocated resources as used in resource calculations. Allocation or
demand models for compute resources are configured in section 3a Capacity and Time Remaining.
Option Description
CPU
Sets a numeric ratio for virtual-to-physical overcommitment.
Memory
Sets a percentage ratio for virtual-to-physical overcommitment.
Disk Space
Sets a percentage ratio for virtual-to-physical overcommitment.
6 Click OK or Finish to save your settings, or select another option to configure.
7 Click Done to close the Configuration dialog box.
The Usage Calculation settings are reconfigured.
Modify the Criteria for Powered-Off and Idle Virtual Machine State
You can specify the amount of time after which the virtual machine is classified as powered-off or idle, and
select the threshold used to detect idle status for 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.
vCenter Operations Manager uses performance counters to measure the activity for a host or virtual
machine. The following counters detect activity thresholds:
n
CPU use in MHz
