6 Examine the Events graph to see if the guest operating system change events or vSphere events caused
the problem.
The guest change events will have a different icon shape.
Address a Problem with a Specific Datastore
Identifying the cause of a problem with a specific datastore involves investigating the I/O intensive virtual
machines that adversely affect the disk space.
Prerequisites
Verify that you are logged in to a vSphere Client and that vCenter Operations Manager is open.
Procedure
1 Search for the problematic datastore name in the vCenter Operations Manager search box.
2 Check the Health, Risk and Efficiency scores for the datastore.
3 If the Risk badge shows that disk I/O is approaching capacity, click the Summary tab under the
Planning tab to view the forecast of resources and constrained resources.
a On the Analysis tab, select the Storage focus area and the Datastore object to view Datastore I/O
Contention Sized by I/O Usage Grouped by Datastore candidates that can accommodate the large
disk I/O virtual machines.
b Move the disk I/O intensive virtual machines to another datastore.
4 If the datastore shows that disk space is approaching capacity, click the Summary tab under the
Planning tab to view the breakdown of the resource capacity usage.
If snapshots occupy a significant amount of disk space, remove snapshots from some of the virtual
machines on the datastore.
5 On the Analysis tab, select the Storage focus area and click Datastore Space Waste Sized by Space Usage
Grouped By Datacenter to list the virtual machines in the datastore.
What to do next
Filter the virtual machines in the red, orange, and yellow states to identify the virtual machines that waste the
most disk space.
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.
