Icinga 2 Configuration Types
============================

:keywords:	Icinga, documentation, configuration
:description:	Description of the Icinga 2 config

Configuration Format
--------------------

Object Definition
~~~~~~~~~~~~~~~~~

Icinga 2 features an object-based configuration format. In order to define
objects the "object" keyword is used:

-------------------------------------------------------------------------------
object Host "host1.example.org" {
  alias = "host1",

  check_interval = 30,
  retry_interval = 15,

  macros = {
    address = "192.168.0.1"
  }
}
-------------------------------------------------------------------------------

NOTE: The Icinga 2 configuration format is agnostic to whitespaces and
new-lines.

Each object is uniquely identified by its type ("Host") and name
("host1.example.org"). Objects can contain a comma-separated list of property
declarations. The following data types are available for property values:

Numeric Literals
^^^^^^^^^^^^^^^^

A floating-point number.

Example:

-------------------------------------------------------------------------------
-27.3
-------------------------------------------------------------------------------

Duration Literal
^^^^^^^^^^^^^^^^

Similar to floating-point numbers except for that fact that they support
suffixes to help with specifying time durations.

Example:

-------------------------------------------------------------------------------
2.5m
-------------------------------------------------------------------------------

Supported suffixes include ms (milliseconds), s (seconds), m (minutes) and h (hours).

String Literals
^^^^^^^^^^^^^^^

A string. No escape characters are supported at present though this will likely
change.

Example:

-------------------------------------------------------------------------------
"Hello World!"
-------------------------------------------------------------------------------

Expression List
^^^^^^^^^^^^^^^

A list of expressions that when executed has a dictionary as a result.

Example:

-------------------------------------------------------------------------------
{
  address = "192.168.0.1",
  port = 443
}
-------------------------------------------------------------------------------

NOTE: Identifiers may not contain certain characters (e.g. space) or start with
certain characters (e.g. digits). If you want to use a dictionary key that is
not a valid identifier you can put the key in double quotes.

Operators
~~~~~~~~~

In addition to the "=" operator shown above a number of other operators to
manipulate configuration objects are supported. Here's a list of all available
operators:

Operator "="
^^^^^^^^^^^^

Sets a dictionary element to the specified value.

Example:

-------------------------------------------------------------------------------
{
  a = 5,
  a = 7
}
-------------------------------------------------------------------------------

In this example a has the value 7 after both instructions are executed.

Operator "+="
^^^^^^^^^^^^^

Modifies a dictionary by adding new elements to it.

Example:

-------------------------------------------------------------------------------
{
  a = { "hello" },
  a += { "world" }
}
-------------------------------------------------------------------------------

In this example a contains both "hello" and "world". This currently only works
for expression lists. Support for numbers might be added later on.

Operator "-="
^^^^^^^^^^^^^

Removes elements from a dictionary.

Example:

-------------------------------------------------------------------------------
{
  a = { "hello", "world" },
  a -= { "world" }
}
-------------------------------------------------------------------------------

In this example a contains "hello". Trying to remove an item that does not
exist is not an error. Not implemented yet.

Operator "*="
^^^^^^^^^^^^^

Multiplies an existing dictionary element with the specified number. If the
dictionary element does not already exist 0 is used as its value.

Example:

-------------------------------------------------------------------------------
{
  a = 60,
  a *= 5
}
-------------------------------------------------------------------------------

In this example a is 300. This only works for numbers. Not implemented yet.

Operator "/="
^^^^^^^^^^^^^

Divides an existing dictionary element by the specified number. If the
dictionary element does not already exist 0 is used as its value.

Example:

-------------------------------------------------------------------------------
{
  a = 300,
  a /= 5
}
-------------------------------------------------------------------------------

In this example a is 60. This only works for numbers. Not implemented yet.

Attribute Shortcuts
~~~~~~~~~~~~~~~~~~~

Value Shortcut
^^^^^^^^^^^^^^

Example:

-------------------------------------------------------------------------------
{
  "hello", "world"
}
-------------------------------------------------------------------------------

This is equivalent to writing:

-------------------------------------------------------------------------------
{
  _00000001 = "hello", _00000002 = "world"
}
-------------------------------------------------------------------------------

The item's keys are monotonically increasing and the config compiler takes
care of ensuring that all keys are unique (even when adding items to an
existing attribute using +=).

Indexer Shortcut
^^^^^^^^^^^^^^^^

Example:

-------------------------------------------------------------------------------
{
  hello["key"] = "world"
}
-------------------------------------------------------------------------------

This is equivalent to writing:

-------------------------------------------------------------------------------
{
  hello += {
    key = "world"
  }
}
-------------------------------------------------------------------------------

Specifiers
~~~~~~~~~~

Objects can have specifiers that have special meaning. The following specifiers
can be used (before the "object" keyword):

Specifier "abstract"
^^^^^^^^^^^^^^^^^^^^

This specifier identifies the object as a template which can be used by other
object definitions. The object will not be instantiated on its own.

Instead of using the "abstract" specifier you can use the "template" keyword
which is a shorthand for writing "abstract object":

-------------------------------------------------------------------------------
template Service "http" {
  ...
}
-------------------------------------------------------------------------------

Specifier "local"
^^^^^^^^^^^^^^^^^

This specifier disables replication for this object. The object will not be
sent to remote Icinga instances.

Inheritance
~~~~~~~~~~~

Objects can inherit attributes from one or more other objects.

Example:

-------------------------------------------------------------------------------
abstract object Host "default-host" {
  check_interval = 30,

  macros = {
    color = "red"
  }
}

abstract object Host "test-host" inherits "default-host" {
  macros += {
    color = "blue"
  }
}

object Host "localhost" inherits "test-host" {
  macros += {
    address = "127.0.0.1",
    address6 = "::1"
  }
}
-------------------------------------------------------------------------------

NOTE: The "default-host" and "test-host" objects are marked as templates using
the "abstract" keyword. Parent objects do not necessarily have to be "abstract"
though in general they are.

NOTE: The += operator is used to insert additional properties into the macros
dictionary. The final dictionary contains all 3 macros and the property "color"
has the value "blue".

Parent objects are resolved in the order they're specified using the "inherits"
keyword. Parent objects must already be defined by the time they're used in an
object definition.

Comments
~~~~~~~~

The Icinga 2 configuration format supports C/C++-style comments.

Example:

-------------------------------------------------------------------------------
/*
 This is a comment.
 */
object Host "localhost" {
  check_interval = 30, // this is also a comment.
  retry_interval = 15
}
-------------------------------------------------------------------------------

Includes
~~~~~~~~

Other configuration files can be included using the "#include" directive. Paths
must be relative to the configuration file that contains the "#include"
keyword:

Example:

-------------------------------------------------------------------------------
#include "some/other/file.conf"
#include "conf.d/*.conf"
-------------------------------------------------------------------------------

Icinga also supports include search paths similar to how they work in a
C/C++ compiler:

-------------------------------------------------------------------------------
#include <itl/itl.conf>
-------------------------------------------------------------------------------

Note the use of angle brackets instead of double quotes. This causes the
config compiler to search the include search paths for the specified file.
By default $PREFIX/icinga2 is included in the list of search paths.

Wildcards are not permitted when using angle brackets.

Library directive
~~~~~~~~~~~~~~~~~

The "#library" directive can be used to manually load additional libraries.
Upon loading these libraries may provide additional classes or methods.

Example:

-------------------------------------------------------------------------------
#library "snmphelper"
-------------------------------------------------------------------------------

NOTE: The "icinga" library is automatically loaded by Icinga.

Type Definition
~~~~~~~~~~~~~~~

By default Icinga has no way of semantically verifying its configuration
objects. This is where type definitions come in. Using type definitions you
can specify which attributes are allowed in an object definition.

Example:

-------------------------------------------------------------------------------
type Pizza {
	%require "radius",
	%attribute number "radius",

	%attribute dictionary "ingredients" {
		%validator "ValidateIngredients",

		%attribute string "*",

		%attribute dictionary "*" {
			%attribute number "quantity",
			%attribute string "name"
		}
	},

	%attribute any "custom::*"
}
-------------------------------------------------------------------------------

The Pizza definition provides the following validation rules:

* Pizza objects must contain an attribute "radius" which has to be a number.
* Pizza objects may contain an attribute "ingredients" which has to be a
dictionary.
* Elements in the ingredients dictionary can be either a string or a dictionary.
* If they're a dictionary they may contain attributes "quantity" (of type
number) and "name" (of type string).
* The script function "ValidateIngredients" is run to perform further
validation of the ingredients dictionary.
* Pizza objects may contain attribute matching the pattern "custom::*" of any
type.

Valid types for type rules include:
* any
* number
* string
* scalar (an alias for string)
* dictionary

Configuration Objects
---------------------

Type: IcingaApplication
~~~~~~~~~~~~~~~~~~~~~~~

The "IcingaApplication" type is used to specify global configuration parameters
for Icinga. There must be exactly one application object in each Icinga 2
configuration. The object must have the "local" specifier.

Example:

-------------------------------------------------------------------------------
local object IcingaApplication "icinga" {
  cert_path = "my-cert.pem",
  ca_path = "ca.crt",

  node = "192.168.0.1",
  service = 7777,

  pid_path = "/var/run/icinga2.pid",
  state_path = "/var/lib/icinga2/icinga2.state",

  macros = {
    plugindir = "/usr/local/icinga/libexec"
  }
}
-------------------------------------------------------------------------------

Attribute: cert_path
^^^^^^^^^^^^^^^^^^^^

This is used to specify the SSL client certificate Icinga 2 will use when
connecting to other Icinga 2 instances. This property is optional when you're
setting up a non-networked Icinga 2 instance.

Attribute: ca_path
^^^^^^^^^^^^^^^^^^

This is the public CA certificate that is used to verify connections from other
Icinga 2 instances. This property is optional when you're setting up a
non-networked Icinga 2 instance.

Attribute: node
^^^^^^^^^^^^^^^

The externally visible IP address that is used by other Icinga 2 instances to
connect to this instance. This property is optional when you're setting up a
non-networked Icinga 2 instance.

NOTE: Icinga does not bind to this IP address.

Attribute: service
^^^^^^^^^^^^^^^^^^

The port this Icinga 2 instance should listen on. This property is optional
when you're setting up a non-networked Icinga 2 instance.

Attribute: pid_path
^^^^^^^^^^^^^^^^^^^

Optional. The path to the PID file. Defaults to "icinga.pid" in the current
working directory.

Attribute: state_path
^^^^^^^^^^^^^^^^^^^^^

Optional. The path of the state file. This is the file Icinga 2 uses to persist
objects between program runs. Defaults to "icinga2.state" in the current working
directory.

Attribute: macros
^^^^^^^^^^^^^^^^^

Optional. Global macros that are used for service checks and notifications.


Type: Component
~~~~~~~~~~~~~~~

Icinga 2 uses a number of components to implement its feature-set. The
"Component" configuration object is used to load these components and specify
additional parameters for them. "Component" objects must have the "local"
specifier. The typical components to be loaded in the default configuration
would be "checker", "delegation" and more.

Example "compat":

-------------------------------------------------------------------------------
local object Component "compat" {
  status_path = "/var/cache/icinga2/status.dat",
  objects_path = "/var/cache/icinga2/objects.cache",
}
-------------------------------------------------------------------------------

Attribute: status_path
^^^^^^^^^^^^^^^^^^^^^^

Specifies where Icinga 2 Compat component will put the status.dat file, which can
be read by Icinga 1.x Classic UI and other addons. If not set, it defaults to the
localstatedir location.

Attribute: objects_path
^^^^^^^^^^^^^^^^^^^^^^^

Specifies where Icinga 2 Compat component will put the objects.cache file, which can
be read by Icinga 1.x Classic UI and other addons. If not set, it defaults to the
localstatedir location.

Type: ConsoleLogger
~~~~~~~~~~~~~~~~~~~

Specifies Icinga 2 logging to the console. Objects of this type must have the
"local" specifier.

Example:

-------------------------------------------------------------------------------
local object ConsoleLogger "my-debug-console" {
  severity = "debug"
}
-------------------------------------------------------------------------------

Attribute: severity
^^^^^^^^^^^^^^^^^^^

The minimum severity for this log. Can be "debug", "information", "warning" or
"critical". Defaults to "information".

Type: FileLogger
~~~~~~~~~~~~~~~~

Specifies Icinga 2 logging to a file. Objects of this type must have the "local"
specifier.

Example:

-------------------------------------------------------------------------------
local object FileLogger "my-debug-file" {
  severity = "debug",
  path = "/var/log/icinga2/icinga2-debug.log"
}
-------------------------------------------------------------------------------


Attribute: path
^^^^^^^^^^^^^^^

The log path.

Attribute: severity
^^^^^^^^^^^^^^^^^^^

The minimum severity for this log. Can be "debug", "information", "warning" or

Type: Endpoint
~~~~~~~~~~~~~~

Endpoint objects are used to specify connection information for remote Icinga 2
instances. Objects of this type should not be local:

  command = "$plugindir$/check_snmp -H $address$ -C $community$ -o $oid$",

  macros = {2yy
    plugindir = "/usr/lib/nagios/plugins",
    address = "127.0.0.1",
    community = "public",
  }
}
-------------------------------------------------------------------------------

object Service "localhost-uptime" {
  host_name = "localhost",

  alias = "localhost Uptime",

  methods = {
    check = "PluginCheck"
  },

  hostgroups = [ "all-hosts" ],

  hostcheck = "ping",
  dependencies = [ "router-ping" ]

  services["ping"] = { templates = "ping" }
  services["http"] = {
    templates = "my-http",
    macros = {
      vhost = "test1.example.org",
      port = 81
    }

object.

The new service's name is "hostname-service" - where "service" is the
array key in the services array.

The priority for service properties is (from highest to lowest):

1. Properties specified in the dictionary of the inline service definition
2. Host properties
3. Properties inherited from the new service's parent object

Configuration Examples
----------------------

Non-networked minimal example
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

NOTE: Icinga 2 ITL provides itl/standalone.conf which loads all required components, as well
as itl/itl.conf includes many object templates already for an easy start with Icinga 2.

-------------------------------------------------------------------------------
local object IcingaApplication "icinga" {

}

local object Component "checker" {

}

local object Component "delegation" {

}

object CheckCommand "ping" {
  command = "$plugindir$/check_ping -H $address$ -w $wrta$,$wpl$% -c $crta$,$cpl$%",
}

template Service "icinga-service" {
  methods = {
    check = "PluginCheck"
  },

  macros = {
    plugindir = "/usr/lib/nagios/plugins"
  }
}

template Service "ping-tmpl" inherits "icinga-service" {
  check_command = "ping",
  macros += {
    wrta = 50,
    wpl = 5,
    crta = 100,
    cpl = 10
  }

  },

  check_interval = 10m
}
-------------------------------------------------------------------------------

NOTE: You may also want to load the "compat" component if you want Icinga 2 to
write status.dat and objects.cache files.
