MySQL 5.7 Reference Manual  /  Group Replication  /  Monitoring Group Replication

17.3 Monitoring Group Replication

Use the Perfomance Schema tables to monitor Group Replication, assuming that MySQL has been compiled with the Performance Schema enabled. Group Replication adds the following two new P_S tables:

  • performance_schema.replication_group_member_stats

  • performance_schema.replication_group_members

These existing Perfomance Schema replication tables also show information regarding Group Replication.

  • performance_schema.replication_connection_status

  • performance_schema.replication_applier_status

The replication channels created by the Group Replication plugin are named:

  • group_replication_recovery - This channel is used for the replication changes that are related to the distributed recovery phase.

  • group_replication_applier - This channel is used for the incoming changes from the group. This is the channel used to apply transactions coming directly from the group.

The following sections describe the information available in each of these tables.
