AlarmEvent

A lifecycle event for a cloud metric alarm attached to an instance.

Emitted when an alarm is registered, reconfigured, removed, or when its firing state changes (e.g., OK → ALARM). State transitions surface as UPDATED — read the latest status from alarm.currentState. Subscribe via environmentEvents or instanceEvents.

type AlarmEvent implements Event {
  action: EventAction!
  timestamp: DateTime!
  alarm: Alarm!
}

Fields

AlarmEvent.action ● EventAction! non-null enum {#action}

AlarmEvent.timestamp ● DateTime! non-null scalar {#timestamp}

AlarmEvent.alarm ● Alarm! non-null object {#alarm}

The alarm that was created, updated, or deleted.

Interfaces

Event interface

Base interface implemented by all lifecycle events.

Every event carries an action describing what happened and a timestamp recording when it occurred. Concrete event types add a field for the affected resource.

Because each subscription returns a union, use an ... on Event fragment to access the shared fields and concrete fragments for the resource payload:

subscription {
  projectEvents(organizationId: "my-org", projectId: "my-project") {
    ... on Event { action timestamp }
    ... on ComponentEvent {
      component { id name }
    }
    ... on LinkEvent {
      link { id fromField toField }
    }
  }
}
