Reserved Keywords

These keywords are reserved by the configuration parser and must not be used as constants or custom attributes.

object
template
include
include_recursive
library
null
partial
true
false
const
apply
to
where
import
assign
ignore
zone
in

You can escape reserved keywords using the @ character. The following example will try to set vars.include which references a reserved keyword and generates the following error:

[2014-09-15 17:24:00 +0200] critical/config: Location:
/etc/icinga2/conf.d/hosts/localhost.conf(13):   vars.sla = "24x7"
/etc/icinga2/conf.d/hosts/localhost.conf(14):
/etc/icinga2/conf.d/hosts/localhost.conf(15):   vars.include = "some cmdb export field"
                                                     ^^^^^^^
/etc/icinga2/conf.d/hosts/localhost.conf(16): }
/etc/icinga2/conf.d/hosts/localhost.conf(17):

Config error: in /etc/icinga2/conf.d/hosts/localhost.conf: 15:8-15:14: syntax error, unexpected include (T_INCLUDE), expecting T_IDENTIFIER
[2014-09-15 17:24:00 +0200] critical/config: 1 errors, 0 warnings.

You can escape the include key with an additional @ character becoming vars.@include:

object Host "localhost" {
  import "generic-host"

  address = "127.0.0.1"
  address6 = "::1"

  vars.os = "Linux"
  vars.sla = "24x7"

  vars.@include = "some cmdb export field"
}

Configuration Syntax

Object Definition

Icinga 2 features an object-based configuration format. You can define new objects using the object keyword:

object Host "host1.example.org" {
  display_name = "host1"

  address = "192.168.0.1"
  address6 = "::1"
}

In general you need to write each statement on a new line. Expressions started with {, ( and [ extend until the matching closing character and can be broken up into multiple lines.

Alternatively you can write multiple statements on a single line by separating them with a semicolon:

object Host "host1.example.org" {
  display_name = "host1"

  address = "192.168.0.1"; address6 = "::1"
}

Each object is uniquely identified by its type (Host) and name (host1.example.org). Some types have composite names, e.g. the Service type which uses the host_name attribute and the name you specified to generate its object name.

Exclamation marks (!) are not permitted in object names.

Objects can contain a comma-separated list of property declarations. Instead of commas semicolons may also be used. The following data types are available for property values:

Expressions

The following expressions can be used on the right-hand side of dictionary values.

Numeric Literals

A floating-point number.

Example:

-27.3

Duration Literals

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

Example:

2.5m

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

Duration literals are converted to seconds by the config parser and are treated like numeric literals.

String Literals

A string.

Example:

"Hello World!"

Certain characters need to be escaped. The following escape sequences are supported:

Character	Escape sequence
"	\"
\	\\
<TAB>	\t
<CARRIAGE-RETURN>	\r
<LINE-FEED>	\n
<BEL>	\b
<FORM-FEED>	\f

In addition to these pre-defined escape sequences you can specify arbitrary ASCII characters using the backslash character (\) followed by an ASCII character in octal encoding.

Multi-line String Literals

Strings spanning multiple lines can be specified by enclosing them in {{{ and }}}.

Example:

{{{This
is
a multi-line
string.}}}

Unlike in ordinary strings special characters do not have to be escaped in multi-line string literals.

Boolean Literals

The keywords true and false are equivalent to 1 and 0 respectively.

Null Value

The null keyword can be used to specify an empty value.

Dictionary

An unordered list of key-value pairs. Keys must be unique and are compared in a case-insensitive manner.

Individual key-value pairs must either be comma-separated or on separate lines. The comma after the last key-value pair is optional.

Example:

{
  address = "192.168.0.1"
  port = 443
}

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 enclose the key in double quotes.

Array

An ordered list of values.

Individual array elements must be comma-separated. The comma after the last element is optional.

Example:

[ "hello", 42 ]

An array may simultaneously contain values of different types, such as strings and numbers.

Operators

The following operators are supported in expressions:

Operator	Examples (Result)	Description
!	!"Hello" (false), !false (true)	Logical negation of the operand
~	~true (false)	Bitwise negation of the operand

   | 1 + 3 (4), "hello " + "world" ("hello world") | Adds two numbers; concatenates strings

   | 3 - 1 (2)                                     | Subtracts two numbers

   | 5m * 10 (3000)                                | Multiplies two numbers

/ | 5m / 5 (60) | Divides two numbers & | 7 & 3 (3) | Binary AND | | 2 | 3 (3) | Binary OR && | true && false (false) | Logical AND || | true || false (true) | Logical OR < | 3 < 5 (true) | Less than

   | 3 > 5 (false)                                 | Greater than

<= | 3 <= 3 (true) | Less than or equal

= | 3 >= 3 (true) | Greater than or equal << | 4 << 8 (1024) | Left shift
  | 1024 >> 4 (64)                                | Right shift

Constants may be used in expressions:

const MyCheckInterval = 10m

...

{
  check_interval = MyCheckInterval / 2.5
}

Function Calls

Functions can be called using the () operator:

const MyGroups = [ "test1", "test" ]

{
  check_interval = len(MyGroups) * 1m
}

Tip

Use these functions in apply rule expressions.

assign where match("192.168.*", host.address)

Function	Description
regex(pattern, text)	Returns true if the regex pattern matches the text, false otherwise.
match(pattern, text)	Returns true if the wildcard pattern matches the text, false otherwise.
len(value)	Returns the length of the value, i.e. the number of elements for an array or dictionary, or the length of the string in bytes.
union(array, array, ...)	Returns an array containing all unique elements from the specified arrays.
intersection(array, array, ...)	Returns an array containing all unique elements which are common to all specified arrays.
keys(dict)	Returns an array containing the dictionary's keys.
string(value)	Converts the value to a string.
number(value)	Converts the value to a number.
bool(value)	Converts the value to a bool.
random()	Returns a random value between 0 and RAND_MAX (as defined in stdlib.h).
log(value)	Writes a message to the log. Non-string values are converted to a JSON string.
log(severity, facility, value)	Writes a message to the log. `severity` can be one of `LogDebug`, `LogNotice`, `LogInformation`, `LogWarning`, and `LogCritical`. Non-string values are converted to a JSON string.
exit(integer)	Terminates the application.

Dictionary Operators

In addition to the = operator shown above a number of other operators to manipulate dictionary elements 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 +=

The += operator is a shortcut. The following expression:

{
  a = [ "hello" ]
  a += [ "world" ]
}

is equivalent to:

{
  a = [ "hello" ]
  a = a + [ "world" ]
}

Operator -=

The -= operator is a shortcut. The following expression:

{
  a = 10
  a -= 5
}

is equivalent to:

{
  a = 10
  a = a - 5
}

Operator *=

The *= operator is a shortcut. The following expression:

{
  a = 60
  a *= 5
}

is equivalent to:

{
  a = 60
  a = a * 5
}

Operator /=

The /= operator is a shortcut. The following expression:

{
  a = 300
  a /= 5
}

is equivalent to:

{
  a = 300
  a = a / 5
}

Indexer

The indexer syntax provides a convenient way to set dictionary elements.

Example:

{
  hello.key = "world"
}

Example (alternative syntax):

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

This is equivalent to writing:

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

Template Imports

Objects can import attributes from other objects.

Example:

template Host "default-host" {
  vars.colour = "red"
}

template Host "test-host" {
  import "default-host"

  vars.colour = "blue"
}

object Host "localhost" {
  import "test-host"

  address = "127.0.0.1"
  address6 = "::1"
}

The default-host and test-host objects are marked as templates using the template keyword. Unlike ordinary objects templates are not instantiated at run-time. Parent objects do not necessarily have to be templates, however in general they are.

The vars dictionary for the localhost object contains all three custom attributes and the custom attribute colour has the value "blue".

Parent objects are resolved in the order they're specified using the import keyword.

Constants

Global constants can be set using the const keyword:

const VarName = "some value"

Once defined a constant can be accessed from any file. Constants cannot be changed once they are set.

There is a defined set of global constants which allow you to specify application settings.

Apply

The apply keyword can be used to create new objects which are associated with another group of objects.

apply Service "ping" to Host {
  import "generic-service"

  check_command = "ping4"

  assign where host.name == "localhost"
}

In this example the assign where condition is a boolean expression which is evaluated for all objects of type Host and a new service with name "ping" is created for each matching host. Expression operators may be used in assign where conditions.

The to keyword and the target type may be omitted if there is only one target type, e.g. for the Service type.

Depending on the object type used in the apply expression additional local variables may be available for use in the where condition:

Source Type	Target Type	Variables
Service	Host	host
Dependency	Host	host
Dependency	Service	host, service
Notification	Host	host
Notification	Service	host, service
ScheduledDowntime	Host	host
ScheduledDowntime	Service	host, service

Any valid config attribute can be accessed using the host and service variables. For example, host.address would return the value of the host's "address" attribute - or null if that attribute isn't set.

Group Assign

Group objects can be assigned to specific member objects using the assign where and ignore where conditions.

object HostGroup "linux-servers" {
  display_name = "Linux Servers"

  assign where host.vars.os == "Linux"
}

In this example the assign where condition is a boolean expression which is evaluated for all objects of the type Host. Each matching host is added as member to the host group with the name "linux-servers". Membership exclusion can be controlled using the ignore where condition. Expression operators may be used in assign where and ignore where conditions.

Source Type	Variables
HostGroup	host
ServiceGroup	host, service
UserGroup	user

Boolean Values

The assign where and ignore where statements, the !, && and || operators as well as the bool() function convert their arguments to a boolean value based on the following rules:

Description	Example Value	Boolean Value
Empty value	null	false
Zero	0	false
Non-zero integer	-23945	true
Empty string	""	false
Non-empty string	"Hello"	true
Empty array	[]	false
Non-empty array	[ "Hello" ]	true
Empty dictionary	{}	false
Non-empty dictionary	{ key = "value" }	true

For a list of supported expression operators for assign where and ignore where statements, see expression operators.

Comments

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

Example:

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

Includes

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

Example:

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

Wildcard includes are not recursive.

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

include <itl>

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/share/icinga2 is included in the list of search paths. Additional include search paths can be added using command-line options.

Wildcards are not permitted when using angle brackets.

Recursive Includes

The include_recursive directive can be used to recursively include all files in a directory which match a certain pattern.

Example:

include_recursive "conf.d", "*.conf"
include_recursive "templates"

The first parameter specifies the directory from which files should be recursively included.

The file names need to match the pattern given in the second parameter. When no pattern is specified the default pattern "*.conf" is used.

Library directive

The library directive can be used to manually load additional libraries. Libraries can be used to provide additional object types and functions.

Example:

library "snmphelper"

Object Types

Host

Example:

object Host "localhost" {
  display_name = "The best host there is"

groups	Optional. An array of nested group names.

Service

Service objects describe network services and how they should be checked by Icinga 2.

Best Practice

Rather than creating a Service object for a specific host it is usually easier to just create a Service template and use the apply keyword to assign the service to a number of hosts. Check the apply chapter for details.

Example:

object Service "uptime" {
  host_name = "localhost"

  display_name = "localhost Uptime"

  check_command = "check_snmp"

  vars.community = "public"
  vars.oid = "DISMAN-EVENT-MIB::sysUpTimeInstance"

ServiceGroup

A group of services.

Best Practice

Assign service group members using the group assign rules.

Example:

object ServiceGroup "snmp" {
  display_name = "SNMP services"
}

  groups = [ "icingaadmins" ]
  email = "icinga@localhost"
  pager = "icingaadmin@localhost.localdomain"

  period = "24x7"

  states = [ OK, Warning, Critical, Unknown ]
  types = [ Problem, Recovery ]

  vars.additional_notes = "This is the Icinga 2 Admin account."
}

Available notification state filters:

OK

}

Attributes:

Name	Description
display_name	Optional. A short description of the user group.
groups	Optional. An array of nested group names.
zone	Optional. The zone this object is a member of.

CheckCommand

A check command definition. Additional default command custom attributes can be defined here.

Example:

object CheckCommand "check_http" {
  import "plugin-check-command"

  command = [ PluginDir + "/check_http" ]

  arguments = {
    "-H" = "$http_vhost$"
    "-I" = "$http_address$"
    "-u" = "$http_uri$"
    "-p" = "$http_port$"
    "-S" = {
      set_if = "$http_ssl$"

    "-e" = "$http_expect$"
  }

  vars.http_address = "$address$"
  vars.http_ssl = false
  vars.http_sni = false
}

Attributes:

Name	Description
execute	Required. The "execute" script method takes care of executing the check. In virtually all cases you should import the "plugin-check-command" template to take care of this setting.
command	Required. The command. This can either be an array of individual command arguments. Alternatively a string can be specified in which case the shell interpreter (usually /bin/sh) takes care of parsing the command. When using the "arguments" attribute this must be an array.
env	Optional. A dictionary of macros which should be exported as environment variables prior to executing the command.
vars	Optional. A dictionary containing custom attributes that are specific to this command.
timeout	Optional. The command timeout in seconds. Defaults to 60 seconds.
zone	Optional. The zone this object is a member of.
arguments	Optional. A dictionary of command arguments.

CheckCommand Arguments

Command arguments can be defined as key-value-pairs in the arguments dictionary. If the argument requires additional configuration for example a description attribute or an optional condition, the value can be defined as dictionary specifying additional options.

Service:

vars.x_val = "My command argument value."
vars.have_x = "true"

CheckCommand:

arguments = {
  "-X" = {
    value = "$x_val$"
key = "-Xnew"	    /* optional, set a new key identifier */
    description = "My plugin requires this argument for doing X."
    required = false    /* optional, no error if not set */
    skip_key = false    /* always use "-X <value>" */
    set_if = "$have_x$" /* only set if variable defined and resolves to a numeric value. String values are not supported */
    order = -1          /* first position */
repeat_key = true   /* if `value` is an array, repeat the key as parameter: ... 'key' 'value[0]' 'key' 'value[1]' 'key' 'value[2]' ... */
  }
  "-Y" = {
    value = "$y_val$"
    description = "My plugin requires this argument for doing Y."
    required = false    /* optional, no error if not set */
    skip_key = true     /* don't prefix "-Y" only use "<value>" */
    set_if = "$have_y$" /* only set if variable defined and resolves to a numeric value. String values are not supported */
    order = 0           /* second position */
repeat_key = false  /* if `value` is an array, do not repeat the key as parameter: ... 'key' 'value[0]' 'value[1]' 'value[2]' ... */
  }
}

Option	Description
value	Optional argument value.
key	Optional argument key overriding the key identifier.
description	Optional argument description.
required	Required argument. Execution error if not set. Defaults to false (optional).
skip_key	Use the value as argument and skip the key.
set_if	Argument is added if the macro resolves to a defined numeric value. String values are not supported.
order	Set if multiple arguments require a defined argument order.
repeat_key	If the argument value is an array, repeat the argument key, or not. Defaults to true (repeat).

Argument order:

  ]

  env = {
    NOTIFICATIONTYPE = "$notification.type$"
    SERVICEDESC = "$service.name$"
    HOSTALIAS = "$host.display_name$"
    HOSTADDRESS = "$address$"
    SERVICESTATE = "$service.state$"

    USEREMAIL = "$user.email$"
  }
}

Attributes:

Command arguments can be used the same way as for CheckCommand objects.

Notification

Notification objects are used to specify how users should be notified in case of host and service state changes and other events.

Best Practice

Rather than creating a Notification object for a specific host or service it is usually easier to just create a Notification template and use the apply keyword to assign the notification to a number of hosts or services. Use the to keyword to set the specific target type for Host or Service. Check the notifications chapter for detailed examples.

Example:

object Notification "localhost-ping-notification" {
  host_name = "localhost"
  service_name = "ping4"

  command = "mail-notification"

  users = [ "user1", "user2" ]

  types = [ Problem, Recovery ]
}

Attributes:

Name	Description
host_name	Required. The name of the host this notification belongs to.
service_name	Optional. The short name of the service this notification belongs to. If omitted this notification object is treated as host notification.
vars	Optional. A dictionary containing custom attributes that are specific to this notification object.
users	Optional. A list of user names who should be notified.
user_groups	Optional. A list of user group names who should be notified.
times	Optional. A dictionary containing `begin` and `end` attributes for the notification.
command	Required. The name of the notification command which should be executed when the notification is triggered.
interval	Optional. The notification interval (in seconds). This interval is used for active notifications. Defaults to 30 minutes. If set to 0, re-notifications are disabled.
period	Optional. The name of a time period which determines when this notification should be triggered. Not set by default.
zone	Optional. The zone this object is a member of.
types	Optional. A list of type filters when this notification should be triggered. By default everything is matched.
states	Optional. A list of state filters when this notification should be triggered. By default everything is matched.

Available notification state filters:

OK
Warning
Critical
Unknown
Up
Down

Available notification type filters:

DowntimeStart
DowntimeEnd
DowntimeRemoved
Custom
Acknowledgement
Problem
Recovery
FlappingStart
FlappingEnd

TimePeriod

Time periods can be used to specify when hosts/services should be checked or to limit when notifications should be sent out.

Example:

object TimePeriod "24x7" {
  import "legacy-timeperiod"

  display_name = "Icinga 2 24x7 TimePeriod"

  ranges = {
    monday = "00:00-24:00"
    tuesday = "00:00-24:00"
    wednesday = "00:00-24:00"
    thursday = "00:00-24:00"
    friday = "00:00-24:00"
    saturday = "00:00-24:00"
    sunday = "00:00-24:00"
  }
}

Attributes:

Name	Description
display_name	Optional. A short description of the time period.
update	Required. The "update" script method takes care of updating the internal representation of the time period. In virtually all cases you should import the "legacy-timeperiod" template to take care of this setting.
zone	Optional. The zone this object is a member of.
ranges	Required. A dictionary containing information which days and durations apply to this timeperiod.

The /etc/icinga2/conf.d/timeperiods.conf file is usually used to define timeperiods including this one.

ScheduledDowntime

ScheduledDowntime objects can be used to set up recurring downtimes for hosts/services.

Best Practice

Rather than creating a ScheduledDowntime object for a specific host or service it is usually easier to just create a ScheduledDowntime template and use the apply keyword to assign the scheduled downtime to a number of hosts or services. Use the to keyword to set the specific target type for Host or Service. Check the recurring downtimes example for details.

Example:

object ScheduledDowntime "some-downtime" {
  host_name = "localhost"
  service_name = "ping4"

  author = "icingaadmin"
  comment = "Some comment"

  fixed = false
  duration = 30m

  ranges = {
    "sunday" = "02:00-03:00"
  }
}

Attributes:

Name	Description
host_name	Required. The name of the host this scheduled downtime belongs to.
service_name	Optional. The short name of the service this scheduled downtime belongs to. If omitted this downtime object is treated as host downtime.
author	Required. The author of the downtime.
comment	Required. A comment for the downtime.
fixed	Optional. Whether this is a fixed downtime. Defaults to true.
duration	Optional. How long the downtime lasts. Only has an effect for flexible (non-fixed) downtimes.
zone	Optional. The zone this object is a member of.
ranges	Required. A dictionary containing information which days and durations apply to this timeperiod.

ScheduledDowntime objects have composite names, i.e. their names are based on the host_name and service_name attributes and the name you specified. This means you can define more than one object with the same (short) name as long as one of the host_name and service_name attributes has a different value.

Dependency

Dependency objects are used to specify dependencies between hosts and services. Dependencies can be defined as Host-to-Host, Service-to-Service, Service-to-Host, or Host-to-Service relations.

Best Practice

Rather than creating a Dependency object for a specific host or service it is usually easier to just create a Dependency template and use the apply keyword to assign the dependency to a number of hosts or services. Use the to keyword to set the specific target type for Host or Service. Check the dependencies chapter for detailed examples.

Service-to-Service Example:

object Dependency "webserver-internet" {
  parent_host_name = "internet"
  parent_service_name = "ping4"

  child_host_name = "webserver"
  child_service_name = "ping4"

  states = [ OK, Warning ]

  disable_checks = true
}

Host-to-Host Example:

object Dependency "webserver-internet" {
  parent_host_name = "internet"

  child_host_name = "webserver"

  states = [ Up ]

  disable_checks = true
}

Attributes:

Name	Description
parent_host_name	Required. The parent host.
parent_service_name	Optional. The parent service. If omitted this dependency object is treated as host dependency.
child_host_name	Required. The child host.
child_service_name	Optional. The child service. If omitted this dependency object is treated as host dependency.
disable_checks	Optional. Whether to disable checks when this dependency fails. Defaults to false.
disable_notifications	Optional. Whether to disable notifications when this dependency fails. Defaults to true.
period	Optional. Time period during which this dependency is enabled.
zone	Optional. The zone this object is a member of.
states	Optional. A list of state filters when this dependency should be OK. Defaults to [ OK, Warning ] for services and [ Up ] for hosts.

Available state filters:

OK
Warning
Critical
Unknown
Up
Down

When using apply rules for dependencies, you can leave out certain attributes which will be automatically determined by Icinga 2.

Service-to-Host Dependency Example:

apply Dependency "internet" to Service {
  parent_host_name = "dsl-router"
  disable_checks = true

  assign where host.name != "dsl-router"
}

This example sets all service objects matching the assign condition into a dependency relation to the parent host object dsl-router as implicit child services.

Service-to-Service-on-the-same-Host Dependency Example:

apply Dependency "disable-nrpe-checks" to Service {
  parent_service_name = "nrpe-health"

  assign where service.check_command == "nrpe"
  ignore where service.name == "nrpe-health"
}

This example omits the parent_host_name attribute and Icinga 2 automatically sets its value to the name of the host object matched by the apply rule condition. All services where apply matches are made implicit child services in this dependency relation.

Dependency objects have composite names, i.e. their names are based on the child_host_name and child_service_name attributes and the name you specified. This means you can define more than one object with the same (short) name as long as one of the child_host_name and child_service_name attributes has a different value.

PerfdataWriter
