Overview

Icinga Web 2 is the associated web interface for the open source monitoring tool Icinga 2. This module helps with installing and managing configuration of Icinga Web 2 and its modules on multiple operating systems.

Description

This module installs and configures Icinga Web 2 on your Linux host by using the official packages from packages.icinga.com. Dependend packages are installed as they are defined in the Icinga Web 2 package.

This module can manage all configurations files of Icinga Web 2 and import an initial database schema. It can install and manage all official modules as well as modules developed by the community.

Setup

What the Icinga 2 Puppet module supports

  • Installation of Icinga Web 2 via packages
  • Configuration
  • MySQL / PostgreSQL database schema import
  • Install and manage official Icinga Web 2 modules
  • Install community modules

Dependencies

This module depends on

Depending on your setup the following modules may also be required:

Limitations

This module has been tested on:

Other operating systems or versions may work but have not been tested.

Usage

NOTE: If you plan to use additional modules from git, the CLI git command has to be installed. You can manage it yourself as package resource or declare the package name in extra_packages.

The usage of this module isn't simple. That depends on how Icinga Web 2 is implemented. Monitoring is here just a module in a framework. All basic stuff like authentication, logging or authorization is done by this framework. To store user and usergroups in a MySQL database, the database has to exist:

mysql::db { 'icingaweb2':
  user     => 'icingaweb2',
  password => 'supersecret',
  host     => 'localhost',
  grant    => [ 'ALL' ],
}

class {'icingaweb2':
  manage_repo    => true,
  import_schema  => true,
  db_type        => 'mysql',
  db_host        => 'localhost',
  db_port        => 3306,
  db_username    => 'icingaweb2',
  db_password    => 'supersecret',
  config_backend => 'db',
  extra_packages => [ 'git' ],
  require        => Mysql::Db['icingaweb2'],
}

If you set import_schema to true an default admin user icingaadmin with password icinga will be created automatically and you're allowed to login.

In case that import_schema is disabled or you'd like to use a different backend for authorization like LDAP, more work is required. At first we need a ressource with credentials to connect a LDAP server:

class {'icingaweb2':
  manage_repo    => true,
}

icingaweb2::config::resource{ 'my-ldap':
  type         => 'ldap',
  host         => 'localhost',
  port         => 389,
  ldap_root_dn => 'ou=users,dc=icinga,dc=com',
  ldap_bind_dn => 'cn=icingaweb2,ou=users,dc=icinga,dc=com',
  ldap_bind_pw => 'supersecret',
}

With the help of this resource, we are now creating user and group backends. Users are permitted to login and users and groups will later be used for authorization.

icingaweb2::config::authmethod { 'ldap-auth':
  backend                  => 'ldap',
  resource                 => 'my-ldap',
  ldap_user_class          => 'user',
  ldap_filter              => '(memberof:1.2.840.113556.1.4.1941:=CN=monitoring,OU=groups,DC=icinga,DC=com)',
  ldap_user_name_attribute => 'cn',
  order                    => '05',
}

icingaweb2::config::groupbackend { 'ldap-groups':
  backend                     => 'ldap',
  resource                    => 'my-ldap',
  ldap_group_class            => 'group',
  ldap_group_name_attribute   => 'cn',
  ldap_group_member_attribute => 'member',
  ldap_base_dn                => 'ou=groups,dc=icinga,dc=com',
  domain                      => 'icinga.com',
}

So that a group gets admin rights a role has to manage:

icingaweb2::config::role { 'default admin user':
  groups      => 'icingaadmins',
  permissions => '*',
}

All available permissions for module monitoring are listed below:

Description Value
Allow everything *
Allow to share navigation items application/share/navigation
Allow to adjust in the preferences whether to show stacktraces application/stacktraces
Allow to view the application log application/log
Grant admin permissions, e.g. manage announcements admin
Allow config access config/*
Allow access to module doc module/doc
Allow access to module monitoring module/monitoring
Allow all commands monitoring/command/*
Allow scheduling host and service checks monitoring/command/schedule-check
Allow acknowledging host and service problems monitoring/command/acknowledge-problem
Allow removing problem acknowledgements monitoring/command/remove-acknowledgement
Allow adding and deleting host and service comments monitoring/command/comment/*
Allow commenting on hosts and services monitoring/command/comment/add
Allow deleting host and service comments monitoring/command/comment/delete
Allow scheduling and deleting host and service downtimes monitoring/command/downtime/*
Allow scheduling host and service downtimes monitoring/command/downtime/schedule
Allow deleting host and service downtimes monitoring/command/downtime/delete
Allow processing host and service check results monitoring/command/process-check-result
Allow processing commands for toggling features on an instance-wide basis monitoring/command/feature/instance
Allow processing commands for toggling features on host and service objects monitoring/command/feature/object/*)

Allow sending custom notifications for hosts and services monitoring/command/send-custom-notification
Allow access to module setup module/setup
Allow access to module test module/test
Allow access to module translation module/translation

Finally we configure the monitoring with the needed connection to the IDO to get information and an API user to send commands to Icinga 2:

class {'icingaweb2::module::monitoring':
  ido_host        => 'localhost',
  ido_db_type     => 'mysql',
  ido_db_name     => 'icinga2',
  ido_db_username => 'icinga2',
  ido_db_password => 'supersecret',
  commandtransports => {
    icinga2 => {
      transport => 'api',
      username  => 'icingaweb2',
      password  => 'supersecret',
    }
  }
}
