repmgr cluster show Displays information about each active node in the replication cluster. This command polls each registered server and shows its role (primary / standby / bdr) and status. It polls each server directly and can be run on any node in the cluster; this is also useful when analyzing connectivity from a particular node. This command requires either a valid repmgr.conf file or a database connection string to one of the registered nodes; no additional arguments are needed. Example: $ repmgr -f /etc/repmgr.conf cluster show ID | Name | Role | Status | Upstream | Location | Connection string ----+-------+---------+-----------+----------+----------+----------------------------------------- 1 | node1 | primary | * running | | default | host=db_node1 dbname=repmgr user=repmgr 2 | node2 | standby | running | node1 | default | host=db_node2 dbname=repmgr user=repmgr 3 | node3 | standby | running | node1 | default | host=db_node3 dbname=repmgr user=repmgr To show database connection errors when polling nodes, run the command in --verbose mode. cluster show accepts an optional parameter --csv, which outputs the replication cluster's status in a simple CSV format, suitable for parsing by scripts: $ repmgr -f /etc/repmgr.conf cluster show --csv 1,-1,-1 2,0,0 3,0,1 The columns have following meanings: node ID availability (0 = available, -1 = unavailable) recovery state (0 = not in recovery, 1 = in recovery, -1 = unknown) Note that the availability is tested by connecting from the node where repmgr cluster show is executed, and does not necessarily imply the node is down.
