Although dashboards are a powerful concept, a dashboard on its own is just a blank canvas. It is the ability for a dashboard to host widgets and their associated configuration that makes the difference. Widgets display the information we want to show in a large variety of different methods.
Most widgets display metric information in the form of scores, graphs, or lists. Widgets can also be linked by interactions, which means, when an object like a virtual machine is selected in one widget, the linked widget(s) will change its data based on the selected object. Some widgets require the use of an additional metric configuration XML file to show specific information that may be required.
