Setting relations

Use set relations to view and compare data between various data sources and resource types based on common metrics. You can set relations between two widgets, between a widget and a dashboard, or between a widget and an external web page or web application. When a widget is broadcasting information, it is the source widget, and is also known as a master widget. When a widget is listening to another widget, it is the target widget, and is also known as listener widget or drill-down widget.

About this task

You can set the following types of communications:
Master-Listener
Sets a widget to widget communication. From a master widget, you can go to a listener widget that displays related details of the master widget object. A synchronization occurs between the master and listener widgets based on common metrics. You can add multiple listener widgets in a master-listener relation. After you set a master-listener relation, you must map the common metric values, else the relation is not established.
Consider the following points when you set master-listener relation between widgets:
  • If you embedded a website or web application within a widget of a dashboard, then you can add such a widget as a listener widget only. Also, you can add only one such widget as a listener widget.
  • If a dashboard contains a widget that lists all instances, then you can set such a widget as a master widget only.
  • If a dashboard contains a multi-chart widget, then all the widgets in that multi-chart widget function as any other dashboard widgets. You can set a master-listener relation between any of the dashboard widgets, irrespective of whether they belong to a multi-chart widget or not.
Drill-down Dashboard
Sets a widget to dashboard communication. A drill-down relation is set between two widgets that belong to two separate dashboards. From a source widget that belongs to one dashboard, you can go to a target widget that belongs to another dashboard. A synchronization occurs between the source widget and the target widget based on common metrics. The target dashboard is the dashboard that contains the target widget and is also known as a drill-down dashboard. If a target dashboard contains multiple widgets, then you need to select a single target widget when you map the common metrics.

You can add only one drill-down dashboard either to a source widget or to a listener widget. After you define a drill-down relation, you cannot set any other relation for that drill-down dashboard. Also, you must map the common metric values in the source widget and the target widget in the drill-down dashboard, else the relation is not established.

Consider the following points when you set drill-down relations:
  • If a drill-down dashboard contains a widget that lists all instances, then you must not select such a widget as a target widget. The all instances custom widget must always be selected as a master widget only.
  • If a drill-down dashboard contains a widget where you embedded a web application or website, then you can select such a widget as a target widget.
  • If a dashboard contains a multi-chart widget, then all the widgets in that multi-chart widget function as any other dashboard widgets. Hence, you can set drill-down relation to these widgets as well.
Drill-down URL
Sets a widget to web page communication. From a source widget, you can go to a target web page that is specified by a URL. If a dashboard contains a multi-chart widget, then all the widgets in that multi-chart widget function as any other dashboard widgets. Hence, you can set drill-down URL relation to these widgets as well. You can add only one drill-down URL either to a source widget or to a listener widget. You cannot add a drill-down URL to a drill-down dashboard in a master-drill-down dashboard relation.
