## Object Types
### Host
A host.
Example:
object Host "localhost" {
display_name = "The best host there is"
groups = [ "all-hosts" ]

}
Attributes:
Name |Description
----------------|----------------

check\_period |**Optional.** The name of a time period which determines when this host should be checked. Not set by default.
check\_interval |**Optional.** The check interval (in seconds). This interval is used for checks when the host 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 host is in a `SOFT` state. Defaults to 1 minute.
enable\_notifications|**Optional.** Whether notifications are enabled. Defaults to true.

display_name = "My hosts"
}
Attributes:
Name |Description
----------------|----------------
display_name |**Optional.** A short description of the host group.
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.
Example:
object Service "uptime" {
host_name = "localhost"
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:
Name |Description
----------------|----------------
host_name |**Required.** The host this service belongs to. There must be a `Host` object with that name.
name |**Required.** The service name. Must be unique on a per-host basis (Similar to the service_description attribute in Icinga 1.x).
groups |**Optional.** The service groups this service belongs to.
In addition to these attributes you can also use any of the attributes which are also valid for `Host` objects.
Service objects have composite names, i.e. their names are based on the host_name attribute and the name you specified. This means
you can define more than one object with the same (short) name as long as the `host_name` attribute has a different value.
### 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.
groups |**Optional.** An array of nested group names.
### 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 use the `apply` keyword to assign the
> notification to a number of services.
Example:
object Notification "localhost-ping-notification" {
host_name = "localhost"
service_name = "ping4"
command = "mail-notification"

### Dependency
Dependency objects are used to specify dependencies between hosts and services.
> **Best Practice**
>
> Rather than creating a `Dependency` object for a specific service it is usually easier
> to just create a `Dependency` template and use the `apply` keyword to assign the
> dependency to a number of services.
Example:
object Dependency "webserver-internet" {
child_host_name = "webserver"
child_service_name = "ping4"

`child_service_name` attributes has a different value.

> **Best Practice**
>
> Rather than creating a `ScheduledDowntime` object for a specific 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 services.
Example:

library "compat"
object CheckResultReader "reader" {
spool_dir = "/data/check-results"
}
Attributes:
Name |Description
----------------|----------------
spool\_dir |**Optional.** The directory which contains the check result files. Defaults to LocalStateDir + "/lib/icinga2/spool/checkresults/".
### CheckerComponent
The checker component is responsible for scheduling active checks. There are no configurable options.
Example:
library "checker"
object CheckerComponent "checker" { }
### NotificationComponent
The notification component is responsible for sending notifications. There are no configurable options.
Example:
library "notification"
object NotificationComponent "notification" { }
### 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 = LocalStateDir + "/cache/icinga2/status.json"
update_interval = 15s
}
Attributes:
Name |Description
--------------------------|--------------------------
status\_path |**Optional.** Path to cluster status file. Defaults to LocalStateDir + "/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](#objecttype-service) object can be restricted using the `domains` attribute
array specifying endpoint privileges.
A Domain object specifices the ACLs applied for each [Endpoint](#objecttype-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.
