// This operation is used with the Amazon GameLift FleetIQ solution and game
// server groups. Retrieves status information about the Amazon EC2 instances
// associated with a Amazon GameLift FleetIQ game server group. Use this operation
// to detect when instances are active or not available to host new game servers.
// To request status for all instances in the game server group, provide a game
// server group ID only. To request status for specific instances, provide the game
// server group ID and one or more instance IDs. Use the pagination parameters to
// retrieve results in sequential segments. If successful, a collection of
// GameServerInstance objects is returned. This operation is not designed to be
// called with every game server claim request; this practice can cause you to
// exceed your API limit, which results in errors. Instead, as a best practice,
// cache the results and refresh your cache no more than once every 10 seconds.
