Determine When an Object Might Run Out of Resources
The Time Remaining pane under the Risks badge provides a summary of when an object in the virtual
environment might run out of resources such as disk space, memory, CPU, or network.
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 Risk tab under the Dashboard tab, and click the arrow under the badge to expand the detailed
view.
3 In the Time Remaining pane, identify the resource that is approaching capacity.
4 Click the Summary tab under the Planning tab.
5 In the Objects and Resources pane, view a breakdown of the remaining capacity and trend information
for each resource.
The Time Remaining value represents an aggregated forecast based on the number of virtual machines
and indicates when capacity might equal resource use.
What to do next
To further investigate which resources constrain the virtual machine count, click the Views tab and select the
Virtual Machine Capacity - Summary view.
Determine the Cause of a Problem with a Specific Object
Determining a cause of a problem with a specific object involves identifying whether the problem is transient
or chronic 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 Check the Health, Risk and Efficiency scores for the object.
n
If any of the scores are in the yellow, orange or red state, click the badge and investigate the sub-
badges.
n
If the problem is because of Health, click the Anomalies badge to check for changes in expected
behavior and the Workload badge to assess whether heavy resource demand exists.
3 Determine whether the demand experienced is for a specific time or whether it indicates a longer trend.
n
If the demand is transient, in the Health pane check the Workload badge.
n
If the problem results from chronic stress, in the Risk pane, check the Stress badge and click the object
in the yellow, orange, or red state.
4 Click the Summary tab under the Planning tab to check the trend and forecast of CPU and memory
demand for that object.
If the object is approaching capacity, consider moving some virtual machines to a less resource-constrained
object.
