|
||||
# 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.
