3 Examine the Total Virtual Machines, Powered-Off Virtual Machines, Undersized Virtual Machines,
Oversized Virtual Machines, and Idle Virtual Machines values to determine how many machines assigned
to this object can be optimized.
Table 4-1. Example of Virtual Machine Optimization - Summary
Virtual Machine Type Number
Total Virtual Machines 12
Powered-Off Virtual Machines 0
Undersized Virtual Machines 6
Oversized Virtual Machines 6
Idle Virtual Machines 1
Identify Powered-Off Virtual Machines to Optimize Data
Powered-off virtual machines in your infrastructure are resources with capacity that you can reclaim.
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 arrow under the Efficiency badge to expand the detailed view.
3 In the Reclaimable Waste pane, identify the powered off virtual machines and delete the virtual click the
Reclaimable Waste badge.
4 In the Views tab, select the Powered-Off Virtual Machines view.
The virtual machines that appear in this view are powered off and you can restart the machines in the
vSphere Client.
What to do next
In the vSphere Client, determine why the virtual machine is powered off. If the virtual machine is obsolete,
you can remove it from the inventory.
Identify Idle Virtual Machines to Optimize Capacity
Optimizing the capacity in the virtual environment involves identifying idle virtual machines that are powered
on but not in use.
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 arrow under the Efficiency badge to expand the detailed view.
3 In the Reclaimable Waste pane, identify the powered off virtual machines and click the Reclaimable
Waste badge.
4 In the Views tab, select the Idle Virtual Machines - List view.
The idle virtual machines in this view either do not perform any work or perform below a specified
threshold.
