Check the Performance of Your Virtual Environment
On the Overview tab under the Environment tab, you can check the performance of your virtual
infrastructure to identify objects with potential performance problems.
You can check the performance of all objects on the vCenter Server that you added for monitoring in
vCenter Operations Manager.
Prerequisites
Verify that you are logged in to a vSphere Client, and that vCenter Operations Manager is open.
Procedure
1 On the Environment tab, click Overview, and click the badge that you want to inspect.
Option Description
Health (default)
Click to check the Health scores of all monitored objects.
Workload
Click to check the Workload scores of all monitored objects.
Anomalies
Click to check the Anomalies scores for all monitored objects.
Faults
Click to check the Faults scores for all monitored objects.
The states of all objects for the metric you selected appear in the Environment tab as colored badges.
2 (Optional) To filter objects by state, use the Status Filter buttons in the upper right of the Overview tab.
What to do next
How you proceed depends on your findings of the performance in your virtual environment.
Balancing the Resources in Your Virtual Environment
You can get an overview of where and why problems exist in your virtual environment, and how the
resources are distributed among objects.
On the Scoreboard tab under the Environment tab, you can compare the performance and available
resources of all child objects of the currently selected object, and look for answers to the following questions.
n
What is the current distribution and availability of resources in my virtual environment?
n
Which hosts have the resources to accommodate new virtual machines?
n
Which hosts require load balancing? Can I move virtual machines from an overloaded host to a less
loaded host?
n
Which child objects have the highest and the lowest scores for health, workload, anomalies, and faults?
