Procedure
1 In the inventory pane, select the object that you want to inspect.
2 If the color of the Health badge is other than green, click the Events tab under the Operations tab to see
events that occurred as far back as a month.
Use the buttons above the badge score graph to control what you see on the Events tab.
3 Point to the abnormal event in the Events graph to view the time range when the problem started to
decrease the possible causes that contributed to the poor badge score.
What to do next
Depending on the details of the event, investigate the problem in vCenter Server.
Identify the Top Resource Consumers
To address high use levels in your virtual environment, identify the top resource consumers.
Prerequisites
Verify that you are logged in to a vSphere Client and that vCenter Operations Manager is open.
Procedure
1 Click the Analysis tab to view the heat map gallery.
2 Depending on the resource, select a CPU, memory, network, or storage focus area.
3 To view a heat map that shows contention by use, select the host, virtual machine, or cluster object.
The larger the size of the heat map tile, the higher the use.
Click the Analysis tab to view the heat map gallery.
4 If a color other than green indicates a potential problem, click Details for the object in the pop-up window
to investigate the resources for that object.
What to do next
Identify the top consumers of resources such as CPU or memory.
Determine the Extent of a Performance Degradation
After you identify the performance problem, determine the effect on the rest of the object population and the
consistency of the issue.
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 Health badge if it is other than green.
3 In the Related Objects pane of the Details tab, verify the color of the Parent Objects and Peer Objects
icons.
n
If the selected object is the only object with a high score, no effect exists on the Peer Objects or Child
Objects.
n
If the Parent Object is in a red, yellow, or orange state, click the Parent Object to investigate the details.
