MySQL 5.7 Reference Manual Including MySQL NDB Cluster 7.5 and NDB Cluster 7.6
SHOW SLAVE HOSTS
Displays a list of replicas currently registered with the source.
SHOW SLAVE HOSTS should be executed on a
server that acts as a replication source. SHOW SLAVE
HOSTS requires the REPLICATION
SLAVE privilege. The statement displays information
about servers that are or have been connected as replicas, with
each row of the result corresponding to one replica server, as
shown here:

+------------+-----------+------+-----------+--------------------------------------+
| Server_id | Host | Port | Master_id | Slave_UUID |

Server_id: The unique server ID of the
replica server, as configured in the replica server's
option file, or on the command line with
--server-id=.
value
Host: The host name of the replica server
as specified on the replica with the
--report-host option. This
can differ from the machine name as configured in the
operating system.
User: The replica server user name as,
specified on the replica with the
--report-user option.
Statement output includes this column only if the source
server is started with the
--show-slave-auth-info
option.
Password: The replica server password as,
specified on the replica with the
--report-password option.
Statement output includes this column only if the source
server is started with the
--show-slave-auth-info
option.
Port: The port on the source to which the
replica server is listening, as specified on the replica
with the --report-port
option.
A zero in this column means that the replica port
(--report-port) was not set.
Master_id: The unique server ID of the
source server that the replica server is replicating from.
This is the server ID of the server on which SHOW
SLAVE HOSTS is executed, so this same value is
listed for each row in the result.
Slave_UUID: The globally unique ID of
this replica, as generated on the replica and found in the
replica's auto.cnf file.
