You can identify the vSphere clusters that are being extensively consumed from a CPU, memory, disk, and network perspective.

You can view all the participating hosts to understand their usage and to determine whether they have any resource contention.

The high or unexpected resource usage on clusters results in performance bottlenecks. You can quickly identify the clusters that are trying to keep up with the virtual machine demand.

When you select a cluster with high CPU, memory, disk or network demand, the dashboard provides you with the list of ESXi hosts that are participating in the given cluster. When you notice an imbalance in how the hosts within the selected clusters are being used, then you can balance the hosts by moving virtual machines within the cluster.

When there is cluster demand with a low-performance history, then the virtual machines must be moved out of these clusters to avoid potential performance issues using Workload Balance. For more information, see Configuring and Using Workload Balance. If such patterns are observed on all the clusters in a given environment, it indicates that there is a requirement for new capacity.
