- Does anybody want to help me fix this? $output seems to be null.

- Added a new parameter so that it displays a specific host's service checks summary. I will update the new version to the main wiki page soon. -- (Smcnaught) 20:18, 4 August 2006 (UTC)

# NagiosStatus Mediawiki extension
#
# original by smcnaught 24.07.2005 - I am also available on irc.chekmate.org #MediaWiki
# Installation:
# * put this file (NagiosStatus.php) into the extension directory of your mediawiki installation
# * add the following to the end of LocalSettings.php: include("extensions/NagiosStatus.php");
# * configure Nagios's web server to allow wiki server to access without username/password
# * remove table's background parameter from skin/monobook/main.css style sheet.
#
# Usage:
# Use one section between <NagiosStatus>-tags for each feed.
#
# Example:
# <NagiosStatus>status</NagiosStatus>
# <NagiosStatus>hosts</NagiosStatus>
# <NagiosStatus>services</NagiosStatus>
# <NagiosStatus>host=10.0.0.1</NagiosStatus>

If you have Nagios configured with authentication
[edit]I was able to get partial success with following change in NagiosStatus.php:
# Nagios CGI-BIN Directory $Nagios_CGI_URL = "http://username:password@server/nagios/cgi-bin/";
Firefox asks for a user and a password, but page is displayed correctly. I get one error in the http log file for each page access. Maybe someone has an idea.
Here is the log error:
Dec 12 11:20:50 2006] [error] [client 171.30.9.14] PHP Notice: Undefined variable: output in /var/www/mwiki/extensions/NagiosStatus.php on line 89, referer: http://server/mwiki/index.php/Main_Page
My Nagios http config file just for referance:
