Working with Overview Performance Charts The overview performance charts provide a single panel in which you view CPU, memory, disk, and network performance charts for the object selected in the inventory. You can view overview charts for clusters, datacenters, datastores, hosts, resource pools, and virtual machines. You can perform the following tasks with the overview performance charts: ■ View all available performance metrics for an object in one panel to easily compare different resource statistics, for example, CPU usage and memory usage. ■ View real-time and historic data. ■ View thumbnail charts for child objects. ■ View the charts for a child object and a parent object. The object names in the thumbnail section are linked to the main charts for that object.
