This command provides an overview over all active nodes in the cluster and the state of each node's repmgrd instance. It can be used to check the result of repmgr daemon pause and repmgr daemon unpause operations.
repmgr daemon status can be executed on any active node in the replication cluster. A valid repmgr.conf file is required.
Note: After restarting PostgreSQL on any node, the repmgrd instance will take a second or two before it is able to update its status. Until then, repmgrd will be shown as not running.
repmgrd running normally on all nodes:
$ repmgr -f /etc/repmgr.conf daemon status ID | Name | Role | Status | repmgrd | PID | Paused? ----+-------+---------+---------+---------+------+--------- 1 | node1 | primary | running | running | 7851 | no 2 | node2 | standby | running | running | 7889 | no 3 | node3 | standby | running | running | 7918 | no
repmgrd paused on all nodes (using repmgr daemon pause):
$ repmgr -f /etc/repmgr.conf daemon status ID | Name | Role | Status | repmgrd | PID | Paused? ----+-------+---------+---------+---------+------+--------- 1 | node1 | primary | running | running | 7851 | yes 2 | node2 | standby | running | running | 7889 | yes 3 | node3 | standby | running | running | 7918 | yes
repmgrd not running on one node:
$ repmgr -f /etc/repmgr.conf daemon status ID | Name | Role | Status | repmgrd | PID | Paused? ----+-------+---------+---------+-------------+------+--------- 1 | node1 | primary | running | running | 7851 | yes 2 | node2 | standby | running | not running | n/a | n/a 3 | node3 | standby | running | running | 7918 | yes
repmgr daemon status accepts an optional parameter --csv, which outputs the replication cluster's status in a simple CSV format, suitable for parsing by scripts, e.g.:
$ repmgr -f /etc/repmgr.conf daemon status --csv
1,node1,primary,1,1,10204,1
2,node2,standby,1,0,-1,1
3,node3,standby,1,1,10225,1
