Object Types

Host

A host.

Note

Unlike in Icinga 1.x hosts are not checkable objects in Icinga 2.

Example:

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

  groups = [ "all-hosts" ],

  host_dependencies = [ "router" ],

  service_dependencies = [
    { host = "db-server", service = "mysql" }
  ],

  services["ping"] = {
    templates = [ "ping" ]
  },

  services["http"] = {
    templates = [ "my-http" ],

    macros = {
      vhost = "test1.example.org",
      port = 81
    }
  },

  check = "ping"
}

Attributes:

Name	Description
display_name	Optional. A short description of the host.
check	Optional. A service that is used to determine whether the host is up or down. This must be a service short name of a service that belongs to the host.
groups	Optional. A list of host groups this host belongs to.
host_dependencies	Optional. A list of host names which this host depends on. These dependencies are used to determine whether the host is unreachable.
service_dependencies	Optional. A list of services which this host depends on. Each array element must be a dictionary containing the keys "host" and "service". These dependencies are used to determine whether the host is unreachable.
services	Optional. Inline definition of services. Each dictionary item specifies a service. The templates attribute can be used to specify an array of templates that should be inherited by the service. The new service's name is "hostname:service" - where "service" is the dictionary key in the services dictionary. The dictionary key is used as the service's short name.
macros	Optional. A dictionary containing macros that are specific to this host.

HostGroup

A group of hosts.

Example:

object HostGroup "my-hosts" {
  display_name = "My hosts",
}

Attributes:

Name	Description
display_name	Optional. A short description of the host group.

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 using the services attribute in the Host object to associate these templates with a host.

Example:

object Service "localhost-uptime" {
  host = "localhost",
  short_name = "uptime",

  display_name = "localhost Uptime",

  check_command = "check_snmp",

  macros = {
    community = "public",
    oid = "DISMAN-EVENT-MIB::sysUpTimeInstance"
  }

  check_interval = 60s,
  retry_interval = 15s,

  servicegroups = [ "all-services", "snmp" ],
}

Attributes:

Name	Description
host	Required. The host this service belongs to. There must be a Host object with that name.
short_name	Required. The service name. Must be unique on a per-host basis (Similar to the service_description attribute in Icinga 1.x).
display_name	Optional. A short description of the service.
macros	Optional. A dictionary containing macros that are specific to this host.
check_command	Required. The name of the check command.
max_check_attempts	Optional. The number of times a service is re-checked before changing into a hard state. Defaults to 3.
check_period	Optional. The name of a time period which determines when this service should be checked. Not set by default.
check_interval	Optional. The check interval (in seconds). This interval is used for checks when the service is in a HARD state. Defaults to 5 minutes.
retry_interval	Optional. The retry interval (in seconds). This interval is used for checks when the service is in a SOFT state. Defaults to 1/5th of the check interval if not specified.
event_command	Optional. The name of an event command that should be executed every time the service's state changes.
flapping_threshold	TODO
volatile	TODO
host_dependencies	Optional. A list of host names which this host depends on. These dependencies are used to determine whether the host is unreachable.
service_dependencies	Optional. A list of services which this host depends on. Each array element must be a dictionary containing the keys "host" and "service". These dependencies are used to determine whether the host is unreachable.
groups	Optional. The service groups this service belongs to.
notifications	Optional. Inline definition of notifications. Each dictionary item specifies a notification. The templates attribute can be used to specify an array of templates that should be inherited by the notification object. The new notification object's name is "hostname:service:notification" - where "notification" is the dictionary key in the notifications dictionary.

ServiceGroup

A group of services.

Example:

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

Attributes:

Name	Description
display_name	Optional. A short description of the service group.

Notification

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

Best Practice

Rather than creating a Notification object for a specific service it is usually easier to just create a Notification template and using the notifications attribute in the Service object to associate these templates with a service.

Example:

object Notification "localhost-ping-notification" {
  host = "localhost",
  service = "ping4",

  notification_command = "mail-notification",

  users = [ "user1", "user2" ]
