The Alarm list widget lists the current state of a Thing's alarms. The dashboard containing the Alarm list widget is usually linked from another widget on a parent dashboard.
For example: The Things listwidget on a parent dashboard can be configured to link to a child dashboard which will pass the Thing key. The passed Thing key will then be used by the Alarm list widget of the child dashboard.
| Field | Description |
|---|---|
| Name | The name of the widget, shown at the top of the widget. |
| Thing definition | The Thing definition which is associated to the alarms. |
| Alarm list heading | The alarm list table headers. You can change the order by clicking the arrows. It is possible to show/hide them by checking/unchecking the Include check box. |
| Alarm list configurations | The list corresponds to the Thing definition you selected. You can change the order by clicking the arrows. Click on the States to Exclude them from showing. |
Interacting with the widget
The widget lists the alarms of a Thing it is linked to, the link is created from a parent widget.
thingKey inheritance
Some widgets may be assigned a thingKey, if they do not have a thingKey defined, they will inherit it from the Dashboard they are on. If the Dashboard doesn't have a thingKey assigned to it directly, it will then inherit from the URL and pass it down to the widget.
thingKey is used for inheriting data. The process of inheritance of thingKey would then be:
-
Widget (optionally defined fixed thingKey on some widgets)
-
Dashboard (defined backup provided to Widget)
-
Url (Optionally provided thingKey overrides dashboard default)
About inheritance, it is important to highlight that the association between parent and child dashboards is purely navigational.
