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.
Overview Performance Charts
The overview performance charts enable you to view CPU, memory, network, disk, and storage metrics for
an object at the same time.
All overview charts for an object appear in the same panel in the Performance tab. This allows you to do side-
by-side comparisions of resource usage for clusters, datacenters, datastores, hosts, resource pools, and virtual
machines. You can perform the following tasks with the overview performance charts.
n
View all charts for an object in one panel. The single-panel view enables you to make side-by-side
comparisons of different resource statistics, for example, CPU usage and memory usage.
n
View real-time and historic data.
n
View thumbnail charts for child objects. Thumbnail charts provide a quick summary of resource usage
for each child object of a datacenter, datastore, cluster, or host.
n
Open the overview charts for a child object by clicking the object name in the thumbnail section.
View the Overview Performance Charts
You can view CPU, memory, disk, network, and storage statistics for an object in the overview performance
charts. These charts support a subset of data counters supported by vCenter Server.
Prerequisites
The vSphere Client must be connected to a vCenter Server system.
Procedure
1 Display the object in the inventory.
2 Select the object and click the Performance tab.
3 Click Overview.
The overview charts for the object appear.
View the Overview Performance Charts Help
The Performance Chart Help contains information on how to work with overview charts, including how to
analyze chart data and how to set the time range for the chart data. It also describes the metric counters
displayed in each overview chart.
Procedure
1 Display the object in the inventory panel.
2 Select the object and click the Performance tab.
