Where to Find Stress-Free Demand and Stress-Free Value
In some areas of the user interface, vRealize Operations Manager identies capacity as Stress Free Demand,
and in other areas it is identied as Stress Free Value. Both terms mean that the calculated capacity for an
object is free from unacceptable levels of contention and stress, as dened in the policy for the Stress score.
Stress Free Demand appears in Troubleshooting > All Metrics, Views, and Reports.
n
In Troubleshooting > All Metrics, you can use the metric named Stress Free Demand to examine the
CPU demand, disk space allocation and demand, memory consumed, and the vSphere conguration
limit on an object. When you apply this metric to these resources, you can build a metric graph to
display the stress-free demand for an object. The graph displays the high and low stress-free capacity
values over time.
n
In Content > Views, when you add or edit a view, in the Data and Conguration areas of the
workspace, you can use the metric named Stress Free Demand. Use this metric to build views for CPU
demand, disk space allocation and demand, memory consumed, and the vSphere conguration limit.
n
In Content > Reports, you can use a view that includes the metric named Stress Free Demand to
generate a report. The table in the report displays Stress Free Demand as the label. For example, this
metric appears in the report named Cluster CPU Demand (%) Trend View.
Stress Free Value appears on the Object > Analysis > Time Remaining tab, and on the Object > Analysis >
Stress tab.
n
On the Object > Analysis > Time Remaining tab, you can view the time remaining for CPU demand,
memory consumed, disk space demand and allocation, and the vSphere conguration limit. In this
view, the table column name is Stress Free Value.
n
On the Object > Analysis > Stress tab, the table column name is Stress Free Value. The tables display
Stress Free Value as the calculated values for CPU demand, memory consumed, and the vSphere
conguration limit.
Setting the Thresholds for the Stress Score
The analysis seings in the policy that you apply to your objects denes the thresholds for the stress score.
The policy includes default seings for the stress score to be green, yellow, orange, or red. If the seings are
too strict or loose for your environment, you can modify them.
To modify the stress score thresholds, edit the policy that applies to your objects, and click Analysis
. Select an object type and click the lter icon to display the policy analysis seings. In the Stress
area, click the lock icon, expand Stress, and modify the stress thresholds.
In the analysis stress seings, vRealize Operations Manager uses the selected resources, such as Memory
Demand, CPU Demand, and vSphere Conguration Limit to calculate the stress score.
You can set the stress thresholds to your own values, or turn them o. To change a stress score threshold,
click and drag an icon along the slider. To remove a scoring range, such as the default range of 35–49
identied by orange, double-click an icon to disable the range.
