repmgr cluster cleanup Purges monitoring history from the repmgr.monitoring_history table to prevent excessive table growth. Use the -k/--keep-history to specify the number of days of monitoring history to retain. This command can be used manually or as a cronjob. This command requires a valid repmgr.conf file for the node on which it is executed; no additional arguments are required. Monitoring history will only be written if repmgrd is active, and monitoring_history is set to true in repmgr.conf.
