Alert object

An Alert object represents the current state of an alert at a given moment. It is returned by the alert listing and single-alert endpoints.

Notes

• id remains stable across the full lifetime of an alert
• metrics is included when the endpoint returns expanded metric data or always includes it by design
• learningStatus is the aggregate learning state for the alert view

Attributes

Field	Type	Description
id	string	Unique alert identifier
lastSeenAt	datetime	Latest event timestamp for this alert state
firstSeenAt	datetime	Timestamp when the alert first appeared
active	boolean	Whether the alert is active at the selected moment

activeNodes	integer	Number of nodes currently participating in the alert
activeMetrics	integer	Number of metrics currently participating in the alert
score	number	Aggregate alert score
learningStatus	number	Aggregate learning-status value for the alert
metrics	array	List of alert metric entries
