Below these controls are the actual performance charts. The layout and the charts that are
included vary based on the object selected and the option chosen in the View drop-down list.

Overview layout. There is only a single chart within this view, but don't let this fool you because
there are a signii cant number of coni guration options for this lone performance chart.
Figure 13.11 shows the Advanced layout of the Performance tab for a cluster of ESXi hosts.
Here, in the Advanced layout, is where the real power of vCenter Server's performance charts is
made available to you.
