The performance charts graphically display CPU, memory, disk, network, and storage metrics for devices and entities managed by vCenter Server. Chart types include line charts, pie charts, bar charts, and stacked charts.

You view the performance charts for an object that is selected in the inventory on the vSphere Client Performance tab. You can view overview charts and advanced charts for an object. Both the overview charts and the advanced charts use the following chart types to display statistics.

Line charts

Display metrics for a single inventory object. The data for each performance counter is plotted on a separate line in the chart. For example, a network chart for a host can contain two lines: one showing the number of packets received, and one showing the number of packets transmitted.

Bar charts

Display storage metrics for datastores in a selected datacenter. Each datastore is represented as a bar in the chart, and each bar displays metrics based on file type (virtual disks, snapshots, swap files, and other files).

Pie charts

Display storage metrics for a single datastore or virtual machine. Storage information is based on file type or virtual machine. For example, a pie chart for a datastore displays the amount of storage space occupied by the five-largest virtual machines on that datastore. A pie chart for a virtual machine displays the amount of storage space occupied by virtual machine files.

Stacked charts

Display metrics for children of the selected parent object. For example, a host's stacked CPU usage chart displays CPU usage metrics for each virtual machine on the host. The metrics for the host itself are displayed in separate line charts. Stacked charts are useful in comparing resource allocation and usage across multiple hosts or virtual machines. Each metric group appears on a separate chart for a managed entity. For example, hosts have one chart that displays CPU metrics and one that displays memory metrics.
