Introduction
This extension allows the wiki server to pull the status page, the host summary or the service summary from your Nagios server. This extension was designed so that the Nagios server could be located on a remote server.
Stay tuned as I may add additional views from Nagios to MediaWiki.
Note: Most up to date version of this extension can be found at: http://www.chekmate.org/wiki/index.php/Projects

[edit]
Define NagiosStatus variables
Modify the following two variables:
// ###### DEFINE VARIABLES TO Nagios Server ###### # Root URL $Nagios_Web_Server = "http://YourNagiosServerHostName/"; # Nagios CGI-BIN Directory $Nagios_CGI_URL = "http://YourNagiosServerHostName/nagios/cgi-bin/";
[edit]
Add to LocalSettings.php
Add the following to the end of LocalSettings.php: include("extensions/NagiosStatus.php");
[edit]
Configure Nagios's Web Server
The Wiki server must be able to pull the status page without any user authentication. This can be accomplished with apache by using "Allow from" and the "Satisfy Any" commands.
In my configuration, it is: (Note: Your configuration will likely be different)
ScriptAlias /nagios/cgi-bin "/usr/local/groundwork/apache2/cgi-bin/nagios"
<Directory "/usr/local/groundwork/apache2/cgi-bin/nagios">
Allow from (IP Address of Wiki Server)
Satisfy Any
AuthType Basic
require valid-user
TKTAuthLoginURL http://NagiosServerIPAddress/monitor/login.php
TKTAuthCookieName nagios_auth_tkt
PassEnv LD_LIBRARY_PATH
</Directory>
[edit]
Modify /skins/monobook/main.css
Comment out backgound in the table style:
table {
/* background: white; */
font-size: 100%;
color: black;
}
[edit]
Usage
Add one of the three following to your wiki pages:
<NagiosStatus>status</NagiosStatus>
<NagiosStatus>hosts</NagiosStatus>
<NagiosStatus>services</NagiosStatus>
