repmgr node check repmgr node check repmgr node check performs some health checks on a node from a replication perspective Performs some health checks on a node from a replication perspective. This command must be run on the local node. $ 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 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: --role: checks if the node has the expected role --replication-lag: checks if the node is lagging by more than replication_lag_warning or replication_lag_critical --archive-ready: checks for WAL files which have not yet been archived --downstream: checks that the expected downstream nodes are attached --slots: checks there are no inactive replication slots Individual checks can also be output in a Nagios-compatible format by additionally providing the option --nagios.
