The Entity Datasource can be used to retrieve various entity model objects from OpenNMS. It currently supports alarms and nodes.

Datasource Queries

The behavior of this datasource changes depending on which entity is chosen. Attributes and values will change depending on the entity type.

Currently the entity datasource only allows a single target. Subsequent targets in the query editor will be ignored.

Template Queries

To change the behavior of a template query (like a datasource variable), you can pass a function to the query field, with an optional attribute argument.

If no attribute argument is given, the query will return the id attribute of th entity.

The default if the query field is empty is alarms() (return a list of alarm IDs).


The alarms() function will query the OpenNMS alarms ReST API.


The nodes() function will query the OpenNMS node ReST API.
