Icinga Web 2 Nagvis Module

Requirements

This module glues NagVis and Icinga Web 2 together. Both of them are required to be installed and configured:

• Icinga Web 2 (>= 2.0.0)
• NagVis (>= 1.8)

NagVis Configuration

This module provides everything for a complete Icinga Web 2 NagVis integration, including authentication and authorisation. To get everything working as expected, your NagVis configuration should contain the following settings:

[global]
authmodule="CoreAuthModIcingaweb2"
authorisationmodule="CoreAuthorisationModIcingaweb2"
logonmodule="LogonIcingaweb2"

[paths]
htmlcgi = "/icingaweb2"

[defaults]
backend = "ndomy_1"
urltarget = "_top"
hosturl="[htmlcgi]/monitoring/host/show?host=[host_name]"
hostgroupurl="[htmlcgi]/monitoring/list/hostgroups?hostgroup_name=[hostgroup_name]"
serviceurl="[htmlcgi]/monitoring/service/show?host=[host_name]&service=[service_description]"
servicegroupurl="[htmlcgi]/monitoring/list/servicegroups?servicegroup=[servicegroup_name]"
mapurl="[htmlcgi]/nagvis/show/map?map=[map_name]"
headermenu="0"
stylesheet="icingaweb-nagvis-integration.css"

The CSS file public/css/icingaweb-nagvis-integration.css must be copied to <nagvisdir>/share/userfiles/styles.

Module Configuration

For many environments the module needs no special configuration. Usually you might want to add a bunch of main maps directly to your menu - this can be done in <ICINGAWEB_CONFIGDIR>/modules/nagvis/config.ini like in the following example:

[global]
default-map = demo-overview

[menu]
demo-germany = Germany
demo-ham-racks = Hamburg

Icinga Web 2 Configuration

Since Icinga Web 2.2.0 session cookies are restricted to /icingaweb2 or your Icinga Web 2 base path. This means that your browser would not send your session cookie to /nagvis and you would not be granted access to NagVis. To solve this please add a section as follows to your Icinga Web 2 configuration in /etc/icingaweb2/config.ini:

[cookie]
path = /

Before doing so please log out from Icinga Web 2 and close your browser, just to be on the safe side. You could otherwise lock your browser in a redirection loop.

PHP code integration

To get the integration running and to allow NagVis to find the configured handlers you need to add a short piece of code to <nagvisdir>/share/server/core/functions/index.php:

/**
 * Icinga Web 2 integration
 */
use Icinga\Application\EmbeddedWeb;

require_once 'Icinga/Application/EmbeddedWeb.php';
require_once EmbeddedWeb::start('/usr/share/icingaweb2', '/etc/icingaweb2')
    ->getModuleManager()
    ->getModule('nagvis')
    ->getLibDir() . '/nagvis-includes/init.inc.php';

This has to sit on top of the page, but after the <?php line.
