复制的监控依旧可以通过SHOW SLAVE STATUS\G，但是MySQL 5.7在performance_schema架构下多了以下这些元数据表，用户可以更细力度的进行监控： ~~~ 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) ~~~
