Object Types

Host

A host.

Example:

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

  groups = [ "all-hosts" ]

  check_command = "hostalive"
}

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.
vars	Optional. A dictionary containing custom attributes that are specific to this host.

HostGroup

A group of hosts.

Example:

}

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 use the apply keyword to assign the service to a number of hosts.

Example:

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

  display_name = "localhost Uptime"

  check_command = "check_snmp"

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

  check_interval = 60s
  retry_interval = 15s

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

Attributes:

IcingaStatusWriter

The IcingaStatusWriter feature periodically dumps the current status and performance data from Icinga 2 and all registered features into a defined JSON file.

Example:

object IcingaStatusWriter "status" {
  status_path = IcingaLocalStateDir + "/cache/icinga2/status.json"
  update_interval = 15s
}

Attributes:

Name	Description
status_path	Optional. Path to cluster status file. Defaults to IcingaLocalStateDir + "/cache/icinga2/status.json"
update_interval	Optional. The interval in which the status files are updated. Defaults to 15 seconds.

ClusterListener

ClusterListener objects are used to specify remote cluster node peers and the certificate files used for ssl authorization.

Example:

library "cluster"

object ClusterListener "cluster" {
  ca_path = "/etc/icinga2/ca/ca.crt"
  cert_path = "/etc/icinga2/ca/icinga-node-1.crt"
  key_path = "/etc/icinga2/ca/icinga-node-1.key"

  bind_port = 8888

  peers = [ "icinga-node-2" ]
}

Attributes:

Name	Description
cert_path	Required. Path to the public key.
key_path	Required. Path to the private key.
ca_path	Required. Path to the CA certificate file.
crl_path	Optional. Path to the CRL file.
bind_host	Optional. The IP address the cluster listener should be bound to.
bind_port	Optional. The port the cluster listener should be bound to.
peers	Optional. A list of

Endpoint

Endpoint objects are used to specify connection information for remote Icinga 2 instances.

Example:

library "cluster"

object Endpoint "icinga-c2" {
  host = "192.168.5.46"
  port = 7777

  config_files = [ "/etc/icinga2/cluster.d/*" ]

  config_files_recursive = [
    "/etc/icinga2/cluster2",
    { path = "/etc/icinga2/cluster3"; pattern = "*.myconf" }
  ]
}

Attributes:

Name	Description
host	Required. The hostname/IP address of the remote Icinga 2 instance.
port	Required. The service name/port of the remote Icinga 2 instance.
config_files	Optional. A list of configuration files sent to remote peers (wildcards possible).
config_files_recursive	Optional. A list of configuration files sent to remote peers. Array elements can either be a string (in which case all files in that directory matching the pattern *.conf are included) or a dictionary with elements "path" and "pattern".
accept_config	Optional. A list of endpoint names from which this endpoint accepts configuration files.

Domain

A Service object can be restricted using the domains attribute array specifying endpoint privileges.

A Domain object specifices the ACLs applied for each Endpoint.

Example:

object Domain "dmz-1" {
  acl = {
    node1 = DomainPrivCheckResult
    node2 = DomainPrivReadWrite
  }
}

Attributes:

Name	Description
acl	Required. Dictionary with items for Domain ACLs.

Domain ACLs:

Name	Description
DomainPrivRead	Endpoint reads local messages and relays them to remote nodes.
DomainPrivCheckResult	Endpoint accepts check result messages from remote nodes.
DomainPrivCommand	Endpoint accepts command messages from remote nodes.
DomainPrevReadOnly	Equivalent to DomainPrivRead.
DomainPrivReadWrite	Equivalent to DomainPrivRead | DomainPrivCheckResult | DomainPrivCommand.
