The Top-N widget displays the top n results from analysis of an object or objects that you select.
How the Top-N Widget and Configuration Options Work
You can select an object when you configure the Top-N widget or you can select an object on another widget. The widget shows an analysis of the applications, alerts, and metrics of an object and its child objects depending on how you configure the widget. The widget can show an analysis of the current values or values over a period of time. You can receive detailed information about each object on the widget. When you double-click an object, the Object Detail page appears.
You can configure a widget to receive data from another widget by selecting Off for Self Provider. You can configure a widget to display results from analysis of an object that you select on the source widget.
For example, you can select a host on a Topology widget and observe the metric analysis of the virtual machines on the host. To set a receiver widget that is on the same dashboard, use the Widget Interactions menu when you edit a dashboard. To set a receiver widget that is on another dashboard, use the Dashboard Navigation menu when you edit a source dashboard.
