Retrieving Role Balancer Status Using the CLI

You can use the maprcli dump rolebalancerinfo command to see the number of active replication role switches. During a replication role switch, the replication role balancer selects a master or intermediate data container and switches its replication role to that of a tail data container.

# maprcli dump rolebalancerinfo -json
                "containerid": 36659,
                "Tail IP:Port":"",
