Assessing Risk and Efficiency in
vCenter Operations Manager 5
vCenter Operations Manager provides workflows for assessing efficient use of the infrastructure as well as
risks to future capacity.
Planning for capacity risk involves analyzing, optimizing, and forecasting data to determine how much
capacity is available and whether you make efficient use of the infrastructure.
This chapter includes the following topics:

Analyzing Data for Capacity Risk
vCenter Operations Manager provides using more than 20 predefined heat maps on the Analysis tab that you
can use to compare commonly used metrics. You can use this data to plan to reduce waste and increase capacity
in the virtual infrastructure.
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.
