Open the VMware Explorer.
2
On the Virtual Infrastructure view, that appears on the navigation panel, select a Virtual Center, ESX host, or virtual machine instance.
3
In the VMware Explorer, open the Processes tab.
Description of Embedded Views

This tab is made up of several embedded views. For complete information about these views, see the Investigating Guest Processes User and Reference Guide.

Related Objects views

At least one Related Objects view is provided in the VMware Explorer dashboard.

Related Objects views are part of the VMware Explorer Primary view and are typically located at the bottom of the Primary view. More than one Related Objects view may appear at a time.

Purpose

Related Objects views provide summary information on either the parent or child objects or both (whichever is applicable) of the object being viewed in the dashboard.

Figure 71. Related Objects views

Related Objects views differ from each other and may not appear at all depending on the object or collection of objects selected from the Virtual Infrastructure view and on the navigation tab selected from the VMware Explorer Primary view heading.

Related Objects views for an individual object display tables that list either the parents or children or both (whichever is applicable) of the selected object, and provide pertinent summary details about each one. The Related Objects view for a collection of objects displays a table that lists all of the objects in the selected collection and provides pertinent summary details about each one. You can sort Related Objects view tables by a particular column by clicking the corresponding column heading. If you select an object from the table by clicking on one of the table rows, all of the views in the VMware Explorer dashboard get updated with information about that object.
