Before you begin
Create or display a view in the Monitoring Dashboard containing charts with metrics data. For information, see Display or create views, charts, and metrics: main steps.
You can display summary notes about several types of objects in the Monitoring Dashboard by positioning the mouse pointer over those objects. To display summary notes about an item, move the mouse pointer to point to the object, and pause. Do not click the mouse. After a momentary delay, a short message about the item is displayed in a note window.
Summary notes are most useful for displaying details about metrics, the MBean instances in which they are defined, and their values as they are plotted in charts. You can also obtain summary notes about items in charts, such as buttons, legends, menus, and so forth, which describe what each item does. For more information, see the following topics:
