# Jean-Samuel Reynaud <js.reynaud@free.fr>
# Based on postgres_locks
#
# Wildcard-plugin to monitor slony latency. To monitor a
# slony cluster, link slony_<cluster_schema> to this file. E.g.
#
# ln -s /usr/share/munin/node/plugins-auto/slony_ /etc/munin/node.d/slony__my_cluster
#
# ...will monitor my_cluster's slony cluster
#
# Show slony latency
#
# Parameters:
#
# config
# autoconf
#
#
#
# Configuration variables:
#
# PGHOST - Database server to use. Defaults to using ident
# authentication with the local server.
# PGPORT - Port to connect to. Defaults to '5432'.
# PGDATABASE - Database to connect to. Defaults to 'template1'.
# PGUSER - User to connect as, if necessary.
# PGPASSWORD - Corresponding password to use, if necessary.
#
# (See libpq documentation for more.)
# Note that PGDATABASE will default to 'template1' in this plugin, and
# without PGHOST it will try ident authentication with the local server,
# as the user that the plugin is running as.
#
# Configuration example:
#
# # Use local server, ident authentication with the 'postgres' user.
# [slony_*]
# user postgres
#
# # Use local server, TCP authentication with a username and password.
# [slony_*]
# env.PGHOST localhost
# env.PGUSER someuser
# env.PGDATABASE somedb
# env.PGPASSWORD somepassword
#
