Discover key points for building and monitoring a powerful cluster.sh.removeRangeFromZone () Removes an association between a range of shard keys and a zone. sh.removeTagRange () In MongoDB 3.4, this method aliases to sh.removeRangeFromZone (). (A shard is a master with one or more replicas.) Alternatively. Know your cluster better and protect it from unauthorized access and avoid downtimes sh.getBalancerState () Returns a boolean to report if the balancer is currently enabled.
