Use the Entities Datasource to retrieve entity model objects from OpenNMS. It currently supports alarms and nodes.
(For an example of the entities datasource in action, see Creating a Filter Panel).
The behavior of this datasource changes depending on which entity is chosen. Attributes and values will change depending on the entity type.
|Currently the entities datasource only allows a single target. Subsequent targets in the query editor will be ignored.|
To change the behavior of a template query, you can pass a field name to the
attribute field to use as the display value of the variable.
If no attribute argument is given, the query will return the
id attribute of the entity.
The default if the
query field is empty is
alarms() (return a list of alarm IDs).
