+
+# Replication settings
+# ---------------------
+
+# when using cascading replication and a standby is to be connected to an
+# upstream standby, specify that node's ID with 'upstream_node'. The node
+# must exist before the new standby can be registered. If a standby is
+# to connect directly to a master node, this parameter is not required.
+#
+# upstream_node=1
+
+# physical replication slots - PostgreSQL 9.4 and later only
+# (default: 0)
+#
+# use_replication_slots=0
+
+
+# Logging and monitoring settings
+# -------------------------------
+
+# Log level: possible values are DEBUG, INFO, NOTICE, WARNING, ERR, ALERT, CRIT or EMERG
+# (default: NOTICE)
+loglevel=NOTICE
+
+# Logging facility: possible values are STDERR or - for Syslog integration - one of LOCAL0, LOCAL1, ..., LOCAL7, USER
+# (default: STDERR)
+logfacility=STDERR
+
+# stderr can be redirected to an arbitrary file:
+#
+# logfile='/var/log/repmgr.log'
+
+# event notifications can be passed to an arbitrary external program
+# together with the following parameters:
+#
+#   %n - node ID
+#   %e - event type
+#   %s - success (1 or 0)
+#   %t - timestamp
+#   %d - details
+#
+# the values provided for "%t" and "%d" will probably contain spaces,
+# so should be quoted in the provided command configuration, e.g.:
+#
+# event_notification_command='/path/to/some/script %n %e %s "%t" "%d"'
+
+# By default, all notifications will be passed; the notification types
+# can be filtered to explicitly named ones:
+#
+# event_notifications=master_register,standby_register,witness_create
+
+
+# Environment/command settings
+# ----------------------------
+
+# path to PostgreSQL binary directory (location of pg_ctl, pg_basebackup etc.)
+# (if not provided, defaults to system $PATH)
+# pg_bindir=/usr/bin/

+# pg_ctl_options='-s'
+# pg_basebackup_options='--xlog-method=s'
+

+# Standby clone settings
+# ----------------------
+#
+# These settings apply when cloning a standby (`repmgr standby clone`).
+
+# Tablespaces can be remapped from one file system location to another:
+#
+# tablespace_mapping=/path/to/original/tablespace=/path/to/new/tablespace
+
+# Don't copy configuration files located outside the data directory.
+#
+# By default repmgr will attempt to copy postgresql.conf, pg_hba.conf and pg_ident.conf
+# from the master, however this may not be desirable if the files are e.g. maintained
+# by configuration management software.
