The Host Usage Overview dashboard provides a view of all the ESXi hosts in your environment in a heat map. The dashboard is suitable for an NOC environment.

Using this dashboard an NOC administrator can easily find resource bottlenecks created due to excessive Memory Demand, Memory Consumption or CPU Demand.

The heat map displays hosts grouped by clusters to help you locate clusters that are using excessive CPU or memory. You can also identify if you have ESXi hosts within the clusters that are not evenly utilized. An administrator can then trigger activities such as workload balance or set DRS to ensure that hot spots are eliminated.
