The Cluster Utilization dashboard helps you identify vSphere clusters that are extensively consumed from a CPU, memory, disk, and network perspective.
You can use this dashboard to identify the clusters that cannot serve the virtual machine demand.
You can select a cluster with high CPU, memory, disk, or network demand. The dashboard lists the ESXi hosts that are a part of the given cluster. If there is an imbalance in the use of hosts within the selected clusters, you can balance the hosts by moving the VMs within the cluster.
You can use this dashboard to view the historical cluster demand. If the situation is critical, use Workload Balance and move the VMs out of the clusters to avoid potential performance issues. For more information, see Configuring and Using Workload Balance. If all the clusters in a given environment display the same pattern, you might have to add new capacity to cater to the increase in demand.
