復制的監控依舊可以通過SHOW SLAVE STATUS\G，但是MySQL 5.7在performance_schema架構下多了以下這些元數據表，用戶可以更細力度的進行監控：
~~~
mysql> show tables like 'replication%';
+---------------------------------------------+
| Tables_in_performance_schema (replication%) |
+---------------------------------------------+
| replication_applier_configuration |
| replication_applier_status |
| replication_applier_status_by_coordinator |
| replication_applier_status_by_worker |
| replication_connection_configuration |
| replication_connection_status |
| replication_group_member_stats |
| replication_group_members |
+---------------------------------------------+
8 rows in set (0.00 sec)
