# Munin plugin to monitor oracle connections w/o DBD::Oracle, or perl for that
|
|
# matter ;-)
|
|
#
|
|
# Author: Kevin Kunkel (kunkel.kevin@gmail.com) on December 11, 2007
|
|
# (Based off the perl munin plugin by Joan Carles Soler)
|
|
#
|
|
# Licenced under GPL v2.
|
|
#
|
|
# Usage:
|
|
#
|
|
# If required, give username, password and/or oracle server
|
|
# host through environment variables.
|
|
#
|
|
# Parameters:
|
|
# autoconf
|
|
# config (required)
|
|
#
|
|
# Config variables:
|
|
#
|
|
# ORACLE_SID - Which database to use. Defaults to orcl
|
|
# oracle_user - A oracle user account with read permission to
|
|
# the v$session view. Defaults to
|
|
# 'oracle'. Anyway, Munin must be told which user
|
|
# this plugin should be run as.
|
|
# oracle_pass - The corresponding password, if
|
|
# applicable. Default to undef.
|
|
#
|
|
# SHOW_ORACLE_USERS - If set to 1 show usernames and num. of connections.
|
|
# Default is not show users (0).
|
|
# Magic markers
