Exclude. After selecting an instances either in the VM resource, CPU, Memory or Potential Zombie VMs instance table, click Exclude to remove the selected instances from calculation.
Show Excluded Items. Click this button to show the instances that have been excluded from calculation.


Use the Settings menu to define the default optimization settings for your environment. The Settings Dialog box provides information about the following components:

Configuration tab

The Configuration tab provides the recommended settings for CPU, memory, and storage optimization.
