MySQL 8.0 Reference Manual  /  Group Replication  /  Monitoring Group Replication

18.3 Monitoring Group Replication

Use the Perfomance Schema tables to monitor Group Replication, assuming that the Performance Schema is enabled. Group Replication adds the following tables:

  • performance_schema.replication_group_member_stats

  • performance_schema.replication_group_members

These Perfomance Schema replication tables also show information about 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.
