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 Environment > Object Browser >All Objects > vCenter Adapter > Cluster Compute Resource > Cost.
You can also view the total host reclaimable cost using
Environment >
Object Browser >
All Objects >
vCenter Adapter >
vSphere World >
Metrics >
Cost.
Note: If the cluster does not have reclaimable hosts, then the cost metric associated with the reclaimable host is not displayed.
