You can use the Capacity Reclaimable dashboard to improve the efficiency of your environment by reducing the wastage of resources.
This dashboard allows you to select an environment and quickly view the amount of capacity which can be reclaimed from the environment in form of reclaimable CPU, Memory and Disk Space.
For more information, see Capacity Reclaimable section in the below vmware blog page.
