Simple Event Attributes Reference

Note: When using an event in a rule’s form editor, type eventname@ to see the list of its attributes.

You can use the following attributes in rules to return information about a simple event instance.

Attribute Type Returns
@id long The event’s unique internal ID.
@extId string The event’s unique external ID. Optional.

The value of the extId is set at creation time, for example, using the event’s ontology function, or the Event.creatEvent() function. The value cannot be changed after that.

Note:
The extId value (if set) must be unique across all objects in the cluster.
Tip:
You can use the property Agent.AgentClassName.checkDuplicates to check for duplicate extIds across the cluster.
@ttl long The event’s time to live, where the assertion of the event defines the start of the time to live period. You can specify the value in the SimpleEvent resource TTL field. See Simple Event Reference .
@payload string The payload as a string value. See Payload (Advanced Tab) for more on specifying the payload in a SimpleEvent resource.
