a In the Health pane, identify the sub-badge that indicates poor score.
b Click the Environment tab under the Operations tab.
c Select the sub-badge that indicated poor score on the Dashboard page.
d Check the Environment tab for badges of related objects that are
indicating problems.
e Double-click an object that indicates poor score.
f On the Details tab under the Operations tab, navigate to the object that
the badge represents and review the resource data, key metrics, and
badge-specific information.

a In the Health pane, identify the sub-badge that indicates poor score and
click it.
b On the Details tab under the Operations tab, review the resource data,
key metrics, and badge-specific information.
What to do next
How you proceed depends on your findings on the Details page.
Identify Objects with Stressed Capacity
Identify the stressed virtual machines, hosts, and clusters that might require more capacity.
Prerequisites
In the vCenter Operations Manager interface, verify that the Dashboard tab is open.
Procedure
1 Click the Risk tab under the Dashboard tab, and click the arrow under the badge to expand the detailed
view.
2 To view the number of any stressed objects, select an object other than a datastore from the inventory
pane.
3 To investigate the details of stressed objects, click the Stress badge.
The Views tab opens.
4 Select the Stress badge and access the view that corresponds to the object.
What to do next
Assign less work to the virtual machines or reconfigure the capacity appropriate to the virtual machine load.
Identify Stressed Hosted or Clusters for Load Balancing
Identify the stressed or undersized hosts and clusters to assign more capacity to those objects and optimize
the load.
Prerequisites
Verify that you are logged in to a vSphere Client and that vCenter Operations Manager is open.
Procedure
1 In the inventory pane, select the object that you want to inspect.
