activityStatus

The progress of the EC2 Fleet.

For fleets of type instant, the status is fulfilled after all requests are placed, regardless of whether target capacity is met (this is the only possible status for instant fleets).

For fleets of type request or maintain, the status is pending_fulfillment after all requests are placed, fulfilled when the fleet size meets or exceeds target capacity, pending_termination while instances are terminating when fleet size is decreased, and error if there's an error.
