The thresholds are evaluated for the period specified for views. You set this period in the Number of
intervals to use text box of the Manage Display Settings section in the Configuration dialog box. For
example, if the default setting for Number of intervals to use is four, and the Interval to use is weekly,
vCenter Operations Manager examines the performance activity for the past month.
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 4a Powered off and idle VMs and change the settings for powered-off and idle virtual machines.
Option Description
% Time Powered-off threshold
Percentage of time during which the virtual machine is powered off.
A virtual machine is considered as powered off by using the following
calculation.
The number of hours that vm is powered off in non-trend
view interval
/ number of hours set in non-trend view >= %time powered
off threshold
Idle VM Detection Rules
% Time Idle threshold
Percentage of time during which the virtual machine is powered on but
inactive, so that you identify the virtual machine as idle.
For a given hour, a virtual machine passes the idle detection criteria for
that hour if it satisfies the resource threshold for all/any specified enabled
resource.
A virtual machine is considered idle by using the followinf calculation.
Number of hours that virtual machine passes the idle
detection criteria in non-trend view interval
/ number of hours in non-trend view >= %time idle threshold
Detection based on any of the
thresholds
If any of the selected counters falls below the minimum threshold, the
virtual machine is considered to be idle.
Detection based on all of the
thresholds
All selected counters must fall below the minimum threshold for the
virtual machine to be considered idle.
Average Resource Usage Criteria
You can select the minimum usage of CPU, Disk I/O, and network
resources to determine the idle detection criteria.
vCenter Operations Manager uses these criteria to determine if the virtual
machine is idle, based on the % Time Idle threshold that you set.
4 Click OK or Finish to save your settings, or select another option to configure.
5 Click Done to close the Configuration dialog box.
