You can use the cost metrics at cluster level to identify the clusters with reclaimable hosts and the potential cost savings from reclaiming these hosts. To know the cost associated with all the reclaimable hosts in a cluster, check the value of Total Host Reclaimable Host Cost metric.

How to View Reclaimable Host Cost

To view the reclaimable host cost, go to Inventory > vCenter Adapter, and then click Cluster Compute Resource > Cost.

You can also view the total host reclaimable cost using Inventory > vCenter Adapter, click vCenter Adapter > vSphere World, and then click Metrics > Cost.
Note: If the cluster does not have reclaimable hosts, then the cost metric associated with the reclaimable host is not displayed.
