Resource Pools Relationship Tree view

Purpose

The Resource Pools Relationship Tree view is provided in the VMware Explorer dashboard. If you select a Resource Pool container from the Topology view on the Virtual Infrastructure view and click the Summary navigation tab within the VMware Explorer Primary view, a Resource Pools Relationship Tree view is displayed in the Primary view. A Resource Pools Relationship Tree contains every resource pool that belongs to the clusters within the associated VirtualCenter.

For more information about the VMware Explorer dashboard, see Investigating performance metrics .

The Resource Pools Relationship Tree view is useful if you want to see how the resource pools within the clusters are laid out or if you want to take a look at the utilization statistics for each configured resource pool on the VirtualCenter.

Figure 72. Resource Pools Relationship Tree view

The default Resource Pools Relationship Tree simply displays the names of the various resource pools and their parent/child relationships.

You can use the Normal Zoom Level button on the mini map at the top right of the Relationship Tree to zoom into a more detailed version of the Tree. You can use the Minimized Zoom Level button on the mini map to zoom back out again.

You can browse through a Relationship Tree by clicking and dragging the rectangular shadow provided on the mini map.
