Option Description
is more than number% for the entire
range
Sets the amount of nonusage in the entire environment defined by the %
underuse thresholds, calculated for the time interval over which the
nonusage is analyzed.
You define the time range in the Manage Display Settings section of the
Configuration dialog box.
Datastores:
Snapshots and templates are
considered waste after numberdays
Determines the number of days since creation when a snapshot or a template
becomes a waste resource. For example, if the waste bin is set to 90 days and
a snapshot is 88 days old, the snapshot is not considered as waste. Only
snapshots or templates that are older than 90 days are considered as waste.
Containers have stress when:
Amount of CPU demand above
Considers the host or cluster stressed when either of the following conditions
are met:
n
CPU use is more than the percentage of its allocated capacity as indicated
in this field.
n
Duration of CPU activity under the threshold compared to total time
evaluated meets the % stressed threshold.
Amount of memory demand above
Considers the host or cluster stressed when either of 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 the threshold compared to total time
evaluated meets the % stressed threshold.
is more than number% for
Sets the amount of use in the entire environment defined by the % stressed
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.
Consider allocation in stress
calculation
Enables an allocation model in calculating stress. Allocation considers
allocated resources as used, and unallocated resources as capacity
remaining.
4 Click OK or Finish to save your settings, or select another option to configure.
5 Click Done to close the Configuration dialog box.
The criteria for underused and stressed capacity are reconfigured.
Determining the Underused and Stressed Capacity Thresholds
You determine the thresholds for underused and stressed capacity on ESX hosts and clusters to define what
is acceptable in your virtual environment.
You can set the underused and stressed capacity thresholds in the 4 Configure state-related thresholds section
of the Edit Policy dialog box.
You determine the time period for which values are computed by using the Usage Work Week setting in the
3c Usage calculation section. By default, vCenter Operations Manager uses a 24-hour period, 7 days a week,
but you can modify this setting. The following examples use the default usage calculation setting.
Underused and stressed capacity thresholds represent the degree to which you allow the resources to be
underused or stressed. Underused and stressed capacity thresholds are computed as an area ratio between the
demand area in the stressed zone and the area of the stressed zone.
Example: Calculating the Thresholds for a Stressed or Underused Resources
To set the thresholds for a one-week interval, open the Configuration dialog box and click Manage Display
Settings. Set the Non-Trend Views Interval to Weekly and select 1 as the number of intervals to use.
