#!/usr/bin/perl -w
# Plugin for monitor oracle locks
#
# Licenced under GPL v2.
#
# Usage:
#
# Symlink into /etc/munin/plugins/ and add the monitored
# database to the filename. e.g.:
#
# ln -s /usr/share/munin/plugins/oracle__locks \
# /etc/munin/plugins/oracle_<databasename>_locks
# This should, however, be given through autoconf and suggest.
#
# If required, give username, password and/or oracle server
# host through environment variables.
#
#
# Parameters:
# autoconf
# config (required)
#
# Config variables:
#
# dbhost - Which database server to use. Defaults to
# 'localhost'.
# dbname - Which database to use. Defaults to template1
# dbuser - A Postgresql user account with read permission to
# the given database. Defaults to
# 'postgres'. Anyway, Munin must be told which user
# this plugin should be run as.
# dbpass - The corresponding password, if
# applicable. Default to undef. Remember that
# pg_hba.conf must be configured accordingly.
#
# Magic markers
#%# family=auto
#%# capabilities=autoconf
