Determine the Timeframe and Nature of a Health Issue on page 43
The Dashboard provides information to help you determine the nature and timeframe of a health issue,
including whether it is a transient or chronic problem.

Determine the Cause of a Problem with a Specific Object on page 44
Determining a cause of a problem with a specific object involves identifying whether the problem is
transient or chronic in the virtual environment.
Determine Whether the Environment Operates as Expected
Anomalies in vCenter Operations Manager provide insight into the behavior of your environment and help
you to determine whether a high workload might still reflect a normal or expected load.
By default, the Dashboard tab displays information about the World object. You can select another object in
the inventory pane to check for immediate health problems on the object. (You can also use the Search text box
at the upper right, entering part or all of the object's name, to locate an object.)
In the Anomalies pane, the blue line represents the actual level of anomalies for the selected object. The gray
line represents the noise threshold line that shows the normal level of anomalies for the selected object.
Prerequisites
In the vCenter Operations Manager interface, verify that the Dashboard tab is open.
Procedure
1 In the inventory pane, select the object that you want to inspect.
2 Click the arrow under the Health badge to expand the detailed view.
3 In the Anomalies pane, check the badge score and the noise threshold line.
If the blue line of the abnormal metric count is far below the noise line, the level of anomalies is normal.
If the blue line of abnormal metric count approaches or surpasses the noise line, the object might be
experiencing health degradation.
4 If you see an abnormal level of anomalies, click the Anomalies badge.
The Details tab opens and you can continue investigating the problem.
What to do next
On the Details tab under the Operations tab, you can check metric values to identify the resource that might
be causing the high Anomalies score. Depending on which resource indicates abnormal operation, check the
Key Metrics pane for further information.
Identify the Source of Performance Degradation
Identifying the probable source of performance degradation in vCenter Operations Manager involves
investigating the percentage of CPU, memory, disks, and network resources usage in the virtual environment.
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.
2 Click the Environment tab under the Operations tab, and select the Workload badge.
3 To filter the objects and related objects by state, click the Status Filter buttons to view only the red, orange,
and yellow states.
