vSphere Client Performance Tab To view performance data on a specific inventory object, select the object and select the Monitor tab. The Performance tab has two tabs in which you can view charts. Overview tab Displays charts containing basic CPU, disk, memory, network, and storage metrics for the selected object and its child objects. The overview performance charts appear by default when you click the Performance tab. Advanced tab Displays a single chart containing CPU, disk, memory, network, or system metrics, depending on the settings that you configure and the metric group that you choose. Advanced charts display statistics that are not supported in the overview performance charts. They also have a mouse-over feature that provides data-point information for a plotted metric. You must manually configure the advanced charts. For information about working with the advanced performance charts, see the vSphere Client Help. Note Storage metrics are not displayed in the advanced charts. You must use the overview charts for datastore information.
