Setting up Icinga 2 User Interfaces

Icinga 2 is compatible to Icinga 1.x user interfaces by providing additional features required as backends.

Furthermore these interfaces (and somewhere in the future an Icinga 2 exclusive interface) can be used for the newly created Icinga Web 2 user interface.

Some interface features will only work in a limited manner due to compatibility reasons, other features like the statusmap parents are available through intelligent compatibility layers for dumping the host dependencies as parents. Special restrictions are noted specifically in the sections below.

Tip

Choose your preferred interface. There's no need to install Classic UI if you prefer Icinga Web or Icinga Web 2 for example.

Setting up Icinga Classic UI

Icinga 2 can write status.dat and objects.cache files in the format that is supported by the Icinga 1.x Classic UI. External commands (a.k.a. the "command pipe") are also supported. It also supports writing Icinga 1.x log files which are required for the reporting functionality in the Classic UI.

Installing Icinga Classic UI

The Icinga package repository has both Debian and RPM packages. You can install the Classic UI using the following packages:

Distribution	Packages
Debian	icinga2-classicui
all others	icinga2-classicui-config icinga-gui

The Debian packages require additional packages which are provided by the Debian Monitoring Project repository.

On all distributions other than Debian you may have to restart both your web server as well as Icinga 2 after installing the Classic UI package.

Verify that your Icinga 1.x Classic UI works by browsing to your Classic UI installation URL:

Distribution	URL	Default Login
Debian	http://localhost/icinga2-classicui	asked during installation
all others	http://localhost/icinga	icingaadmin/icingaadmin

Setting up Icinga Web

Icinga 2 can write to the same schema supplied by Icinga IDOUtils 1.x which is an explicit requirement to run Icinga Web next to the external command pipe. Therefore you need to setup the DB IDO feature remarked in the previous sections.

Installing Icinga Web

The Icinga package repository has both Debian and RPM packages. You can install the Classic UI using the following packages:

Distribution	Packages
RHEL/SUSE	icinga-web icinga-web-{mysql,pgsql}
Debian	icinga-web

Additionally you need to setup the icinga_web database.

The Icinga Web RPM packages install the schema files into /usr/share/doc/icinga-web-*/schema (* means package version). The Icinga Web dist tarball ships the schema files in etc/schema.

On SuSE-based distributions the schema files are installed in /usr/share/doc/packages/icinga-web/schema.

Additionally you need to enable the command feature:

# icinga2-enable-feature command

Then edit the Icinga Web configuration for sending commands in /etc/icinga-web/conf.d/access.xml (RHEL) or /etc/icinga-web/access.xml (SUSE) setting the command pipe path to the default used in Icinga 2. Make sure to clear the cache afterwards.

# vim /etc/icinga-web/conf.d/access.xml

            <write>
                <files>
                    <resource name="icinga_pipe">/var/run/icinga2/cmd/icinga.cmd</resource>
                </files>
            </write>

# icinga-web-clearcache

Verify that your Icinga 1.x Web works by browsing to your Web installation URL:

Distribution	URL	Default Login
Debian	http://localhost/icinga-web	asked during installation
all others	http://localhost/icinga-web	root/password

Setting up Icinga Web 2

Icinga Web 2 currently supports status.dat, DB IDO, or Livestatus as backends. Please consult the INSTALL documentation shipped with Icinga Web 2 for further instructions.

Icinga Web 2 is still under development. Rather than installing it yourself you should consider testing it using the available Vagrant demo VM.

Additional visualization

There are many visualization addons which can be used with Icinga 2.

Some of the more popular ones are PNP, inGraph (graphing performance data), Graphite, and NagVis (network maps).
