Use the Details window to view the current values for specific data properties, such as the amount of memory being used on a given host. You can navigate through the hierarchy (tree) view to find the appropriate managed object. The lowest-level object in the host hierarchy is the monitored property.
By default, information about a monitored data property is displayed in table form. In some instances, viewing that information in a graph can be useful. For example, to see when memory usage is highest, you might create a graph of the memory usage as a function of time.
