Performance and conflict statistics are maintained for each node by BDR in the bdr.pg_stat_bdr table. This table is not replicated between nodes, so each node has separate stats. Each row represents the BDR apply statistics for a different peer node.
An example listing from this table might look like:
SELECT * FROM bdr.pg_stat_bdr; rep_node_id | rilocalid | riremoteid | nr_commit | nr_rollback | nr_insert | nr_insert_conflict | nr_update | nr_update_conflict | nr_delete | nr_delete_conflict | nr_disconnect -------------+-----------+----------------------------------------+-----------+-------------+-----------+--------------------+-----------+--------------------+-----------+--------------------+--------------- 1 | 1 | bdr_6127682459268878512_1_16386_16386_ | 4 | 0 | 6 | 0 | 1 | 0 | 0 | 3 | 0 2 | 2 | bdr_6127682494973391064_1_16386_16386_ | 1 | 0 | 0 | 0 | 1 | 0 | 0 | 0 | 0 (2 rows)
