Performs some health checks on a node from a replication perspective. This command must be run on the local node.
Note: Currently repmgr performs health checks on physical replication slots only, with the aim of warning about streaming replication standbys which have become detached and the associated risk of uncontrolled WAL file growth.
$ repmgr -f /etc/repmgr.conf node check Node "node1": Server role: OK (node is primary) Replication lag: OK (N/A - node is primary) WAL archiving: OK (0 pending files) Downstream servers: OK (2 of 2 downstream nodes attached) Replication slots: OK (node has no physical replication slots) Missing replication slots: OK (node has no missing physical replication slots)
Each check can be performed individually by supplying an additional command line parameter, e.g.:
$ repmgr node check --role OK (node is primary)
Parameters for individual checks are as follows:
When executing repmgr node check with one of the individual checks listed above, repmgr will emit one of the following Nagios-style exit codes (even if --nagios is not supplied):
One of the following exit codes will be emitted by repmgr status check if no individual check was specified.
