repmgr node check

Description

Performs some health checks on a node from a replication perspective. This command must be run on the local node.

Example

       $ 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)

Individual checks

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• --archive-ready: checks for WAL files which have not yet been archived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

Output format

• --csv: generate output in CSV format (not available for individual checks)
• --nagios: generate output in a Nagios-compatible format
