	//   more information, see the description of the event.
	//
	// fleetRequestChange events:
	//
	//   - active - The EC2 Fleet or Spot Fleet request has been validated and Amazon

	//
	//   - deleted (EC2 Fleet) / cancelled (Spot Fleet) - The EC2 Fleet is deleted or

	//   or Spot Fleet will be deleted two days after its instances are terminated.
	//
	//   - deleted_running (EC2 Fleet) / cancelled_running (Spot Fleet) - The EC2 Fleet
	//   is deleted or the Spot Fleet request is canceled and does not launch additional
	//   instances. Its existing instances continue to run until they are interrupted or
	//   terminated. The request remains in this state until all instances are

	//
	//   - deleted_terminating (EC2 Fleet) / cancelled_terminating (Spot Fleet) - The
	//   EC2 Fleet is deleted or the Spot Fleet request is canceled and its instances are
	//   terminating. The request remains in this state until all instances are
	//   terminated.
	//
	//   - expired - The EC2 Fleet or Spot Fleet request has expired. If the request

	//   event indicates that the instances are terminated.
	//
	//   - modify_in_progress - The EC2 Fleet or Spot Fleet request is being modified.

	//   fulfilled.

	//
	//   - launched - A new instance was launched.
	//
	//   - terminated - An instance was terminated by the user.

	//   - termination_notified - An instance termination notification was sent when a
	//   Spot Instance was terminated by Amazon EC2 during scale-down, when the target
	//   capacity of the fleet was modified down, for example, from a target capacity of
	//   4 to a target capacity of 3.

	// Information events:

	//   - fleetProgressHalted - The price in every launch specification is not valid
