1 # Config Object Types <a id="object-types"></a>
3 This chapter provides an overview of all available config object types which can be
4 instantiated using the `object` keyword.
6 Additional details on configuration and runtime attributes and their
7 description are explained as well.
9 Config objects share these runtime attributes which cannot be
10 modified by the user. You can access these attributes using
11 the [Icinga 2 API](12-icinga2-api.md#icinga2-api-config-objects).
14 --------------------------|--------------------------
15 version | Timestamp when the object was created or modified. Synced throughout cluster nodes.
17 original_attributes | Original values of object attributes modified at runtime.
18 active | Object is active (e.g. a service being checked).
19 paused | Object has been paused at runtime (e.g. [IdoMysqlConnection](09-object-types.md#objecttype-idomysqlconnection). Defaults to `false`.
20 templates | Templates imported on object compilation.
21 package | [Configuration package name](12-icinga2-api.md#icinga2-api-config-management) this object belongs to. Local configuration is set to `_etc`, runtime created objects use `_api`.
24 ## ApiListener <a id="objecttype-apilistener"></a>
26 ApiListener objects are used for distributed monitoring setups
27 and API usage specifying the certificate files used for ssl
28 authorization and additional restrictions.
30 The `NodeName` constant must be defined in [constants.conf](04-configuring-icinga-2.md#constants-conf).

160 set_if = "$have_x$" /* only set if variable defined and resolves to a numeric value. String values are not supported */
161 order = -1 /* first position */
162 repeat_key = true /* if `value` is an array, repeat the key as parameter: ... 'key' 'value[0]' 'key' 'value[1]' 'key' 'value[2]' ... */
166 description = "My plugin requires this argument for doing Y."
167 required = false /* optional, no error if not set */
168 skip_key = true /* don't prefix "-Y" only use "<value>" */
169 set_if = "$have_y$" /* only set if variable defined and resolves to a numeric value. String values are not supported */
170 order = 0 /* second position */
171 repeat_key = false /* if `value` is an array, do not repeat the key as parameter: ... 'key' 'value[0]' 'value[1]' 'value[2]' ... */
176 ------------|--------------
177 value | Optional argument value set by a macro string or a function call.

194 Argument array `repeat_key = false`:
196 `'key' 'value[0]' 'value[1]' 'value[2]'`
198 ## CheckerComponent <a id="objecttype-checkcomponent"></a>

271 rotation_method = "HOURLY"
274 Configuration Attributes:
277 ----------------|----------------
278 log\_dir |**Optional.** Path to the compat log directory. Defaults to LocalStateDir + "/log/icinga2/compat".
279 rotation\_method|**Optional.** Specifies when to rotate log files. Can be one of "HOURLY", "DAILY", "WEEKLY" or "MONTHLY". Defaults to "HOURLY".
283 ## Dependency <a id="objecttype-dependency"></a>
285 Dependency objects are used to specify dependencies between hosts and services. Dependencies
286 can be defined as Host-to-Host, Service-to-Service, Service-to-Host, or Host-to-Service
291 > Rather than creating a `Dependency` object for a specific host or service it is usually easier
292 > to just create a `Dependency` template and use the `apply` keyword to assign the
293 > dependency to a number of hosts or services. Use the `to` keyword to set the specific target
294 > type for `Host` or `Service`.
295 > Check the [dependencies](03-monitoring-basics.md#dependencies) chapter for detailed examples.
297 Service-to-Service Example:
299 object Dependency "webserver-internet" {
300 parent_host_name = "internet"
301 parent_service_name = "ping4"
303 child_host_name = "webserver"
304 child_service_name = "ping4"
306 states = [ OK, Warning ]
308 disable_checks = true
311 Host-to-Host Example:
313 object Dependency "webserver-internet" {
314 parent_host_name = "internet"
316 child_host_name = "webserver"
320 disable_checks = true
323 Configuration Attributes:
326 ----------------------|----------------
327 parent_host_name |**Required.** The parent host.
328 parent_service_name |**Optional.** The parent service. If omitted, this dependency object is treated as host dependency.
329 child_host_name |**Required.** The child host.
330 child_service_name |**Optional.** The child service. If omitted, this dependency object is treated as host dependency.
331 disable_checks |**Optional.** Whether to disable checks when this dependency fails. Defaults to false.
332 disable_notifications |**Optional.** Whether to disable notifications when this dependency fails. Defaults to true.
333 ignore_soft_states |**Optional.** Whether to ignore soft states for the reachability calculation. Defaults to true.
334 period |**Optional.** Time period during which this dependency is enabled.
335 states |**Optional.** A list of state filters when this dependency should be OK. Defaults to [ OK, Warning ] for services and [ Up ] for hosts.
337 Available state filters:
346 When using [apply rules](03-monitoring-basics.md#using-apply) for dependencies, you can leave out certain attributes which will be
347 automatically determined by Icinga 2.
349 Service-to-Host Dependency Example:
351 apply Dependency "internet" to Service {
352 parent_host_name = "dsl-router"
353 disable_checks = true
355 assign where host.name != "dsl-router"
358 This example sets all service objects matching the assign condition into a dependency relation to
359 the parent host object `dsl-router` as implicit child services.
361 Service-to-Service-on-the-same-Host Dependency Example:
363 apply Dependency "disable-nrpe-checks" to Service {
364 parent_service_name = "nrpe-health"
366 assign where service.check_command == "nrpe"
367 ignore where service.name == "nrpe-health"
370 This example omits the `parent_host_name` attribute and Icinga 2 automatically sets its value to the name of the
371 host object matched by the apply rule condition. All services where apply matches are made implicit child services
372 in this dependency relation.
375 Dependency objects have composite names, i.e. their names are based on the `child_host_name` and `child_service_name` attributes and the
376 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
377 `child_service_name` attributes has a different value.
379 ## Downtime <a id="objecttype-downtime"></a>
381 Downtimes created at runtime are represented as objects.

391 Configuration Attributes:
394 ----------------|----------------
395 host_name | **Required.** The name of the host this comment belongs to.
396 service_name | **Optional.** The short name of the service this comment belongs to. If omitted, this comment object is treated as host comment.
397 author | **Required.** The author's name.
398 comment | **Required.** The comment text.
399 start_time | **Required.** The start time as unix timestamp.

423 host = "192.168.5.46"
428 Example (disable replay log):
430 object Endpoint "icinga2b" {
431 host = "192.168.5.46"
436 Configuration Attributes:
439 ----------------|----------------
440 host |**Optional.** The hostname/IP address of the remote Icinga 2 instance.
441 port |**Optional.** The service name/port of the remote Icinga 2 instance. Defaults to `5665`.

456 object EventCommand "restart-httpd-event" {
457 command = "/opt/bin/restart-httpd.sh"
461 Configuration Attributes:
464 ----------------|----------------
465 execute |**Required.** The "execute" script method takes care of executing the event handler. The default template "plugin-event-command" which is imported into all CheckCommand objects takes care of this setting.

869 ## InfluxdbWriter <a id="objecttype-influxdbwriter"></a>
871 Writes check result metrics and performance data to a defined InfluxDB host.
877 object InfluxdbWriter "influxdb" {
882 flush_threshold = 1024
886 measurement = "$host.check_command$"
888 hostname = "$host.name$"
892 measurement = "$service.check_command$"
894 hostname = "$host.name$"
895 service = "$service.name$"
900 Measurement names and tags are fully configurable by the end user. The InfluxdbWriter
901 object will automatically add a `metric` tag to each data point. This correlates to the
902 perfdata label. Fields (value, warn, crit, min, max) are created from data if available
903 and the configuration allows it. If a value associated with a tag is not able to be
904 resolved, it will be dropped and not sent to the target host.
906 Backslashes are allowed in tag keys, tag values and field keys, however they are also
907 escape characters when followed by a space or comma, but cannot be escaped themselves.
908 As a result all trailling slashes in these fields are replaced with an underscore. This
909 predominantly affects Windows paths e.g. `C:\` becomes `C:_`.
911 The database is assumed to exist so this object will make no attempt to create it currently.
913 Configuration Attributes:
916 -----------------------|---------------------------------------------------------------------------------------------------------
917 host | **Required.** InfluxDB host address. Defaults to `127.0.0.1`.
918 port | **Required.** InfluxDB HTTP port. Defaults to `8086`.
919 database | **Required.** InfluxDB database name. Defaults to `icinga2`.
920 username | **Optional.** InfluxDB user name. Defaults to `none`.
921 password | **Optional.** InfluxDB user password. Defaults to `none`.
922 ssl_enable | **Optional.** Whether to use a TLS stream. Defaults to `false`.
923 ssl_ca_cert | **Optional.** CA certificate to validate the remote host.
924 ssl_cert | **Optional.** Host certificate to present to the remote host for mutual verification.
925 ssl_key | **Optional.** Host key to accompany the ssl_cert
926 host_template | **Required.** Host template to define the InfluxDB line protocol.
927 service_template | **Required.** Service template to define the influxDB line protocol.
928 enable_send_thresholds | **Optional.** Whether to send warn, crit, min & max tagged data.
929 enable_send_metadata | **Optional.** Whether to send check metadata e.g. states, execution time, latency etc.
930 flush_interval | **Optional.** How long to buffer data points before transfering to InfluxDB. Defaults to `10s`.
931 flush_threshold | **Optional.** How many data points to buffer before forcing a transfer to InfluxDB. Defaults to `1024`.
933 Note: If `flush_threshold` is set too low, this will always force the feature to flush all data
934 to InfluxDB. Experiment with the setting, if you are processing more than 1024 metrics per second
937 ### Instance Tagging <a id="objecttype-influxdbwriter-instance-tags"></a>
939 Consider the following service check:
941 apply Service "disk" for (disk => attributes in host.vars.disks) {
942 import "generic-service"
943 check_command = "disk"
944 display_name = "Disk " + disk
945 vars.disk_partitions = disk
946 assign where host.vars.disks
949 This is a typical pattern for checking individual disks, NICs, SSL certificates etc associated
950 with a host. What would be useful is to have the data points tagged with the specific instance
951 for that check. This would allow you to query time series data for a check on a host and for a
952 specific instance e.g. /dev/sda. To do this quite simply add the instance to the service variables:
954 apply Service "disk" for (disk => attributes in host.vars.disks) {
960 Then modify your writer configuration to add this tag to your data points if the instance variable
961 is associated with the service:
963 object InfluxdbWriter "influxdb" {
966 measurement = "$service.check_command$"
968 hostname = "$host.name$"
969 service = "$service.name$"
970 instance = "$service.vars.instance$"
976 ## ElasticWriter <a id="objecttype-elasticwriter"></a>
978 Writes check result metrics and performance data to an Elasticsearch instance.
984 object ElasticWriter "elastic" {
989 enable_send_perfdata = true
991 flush_threshold = 1024
995 The index is rotated daily, as is recommended by Elastic, meaning the index will be renamed to `$index-$d.$M.$y`.
997 Configuration Attributes:
1000 -----------------------|---------------------------------------------------------------------------------------------------------
1001 host | **Required.** Elasticsearch host address. Defaults to `127.0.0.1`.
1002 port | **Required.** Elasticsearch port. Defaults to `9200`.
1003 index | **Required.** Elasticsearch index name. Defaults to `icinga2`.
1004 enable\_send\_perfdata | **Optional.** Send parsed performance data metrics for check results. Defaults to `false`.
1005 flush\_interval | **Optional.** How long to buffer data points before transfering to Elasticsearch. Defaults to `10`.
1006 flush\_threshold | **Optional.** How many data points to buffer before forcing a transfer to Elasticsearch. Defaults to `1024`.
1007 username | **Optional.** Basic auth username if Elasticsearch is hidden behind an HTTP proxy.
1008 password | **Optional.** Basic auth password if Elasticsearch is hidden behind an HTTP proxy.
1009 enable\_tls | **Optional.** Whether to use a TLS stream. Defaults to `false`. Requires an HTTP proxy.
1010 ca\_path | **Optional.** CA certificate to validate the remote host. Requires `enable_tls` set to `true`.
1011 cert\_path | **Optional.** Host certificate to present to the remote host for mutual verification. Requires `enable_tls` set to `true`.
1012 key\_path | **Optional.** Host key to accompany the cert\_path. Requires `enable_tls` set to `true`.
1014 Note: If `flush_threshold` is set too low, this will force the feature to flush all data to Elasticsearch too often.
1015 Experiment with the setting, if you are processing more than 1024 metrics per second or similar.
1017 Basic auth is supported with the `username` and `password` attributes. This requires an
1018 HTTP proxy (Nginx, etc.) in front of the Elasticsearch instance.
1020 TLS for the HTTP proxy can be enabled with `enable_tls`. In addition to that
1021 you can specify the certificates with the `ca_path`, `cert_path` and `cert_key` attributes.
1023 ## LiveStatusListener <a id="objecttype-livestatuslistener"></a>
1025 Livestatus API interface available as TCP or UNIX socket. Historical table queries
1026 require the [CompatLogger](09-object-types.md#objecttype-compatlogger) feature enabled
1027 pointing to the log files using the `compat_log_path` configuration attribute.
1031 library "livestatus"
1033 object LivestatusListener "livestatus-tcp" {
1035 bind_host = "127.0.0.1"
1039 object LivestatusListener "livestatus-unix" {
1040 socket_type = "unix"

1050 bind\_port |**Optional.** Only valid when `socket_type` is "tcp". Port to listen on for connections. Defaults to 6558.
1051 socket\_path |**Optional.** Only valid when `socket_type` is "unix". Specifies the path to the UNIX socket file. Defaults to RunDir + "/icinga2/cmd/livestatus".
1052 compat\_log\_path |**Optional.** Required for historical table queries. Requires `CompatLogger` feature enabled. Defaults to LocalStateDir + "/log/icinga2/compat"
1056 > UNIX sockets are not supported on Windows.
1059 ## Notification <a id="objecttype-notification"></a>
1061 Notification objects are used to specify how users should be notified in case
1062 of host and service state changes and other events.
1066 > Rather than creating a `Notification` object for a specific host or service it is
1067 > usually easier to just create a `Notification` template and use the `apply` keyword
1068 > to assign the notification to a number of hosts or services. Use the `to` keyword
1069 > to set the specific target type for `Host` or `Service`.

1348 ScheduledDowntime objects have composite names, i.e. their names are based
1349 on the `host_name` and `service_name` attributes and the
1350 name you specified. This means you can define more than one object
1351 with the same (short) name as long as one of the `host_name` and
1352 `service_name` attributes has a different value.
1355 ## Service <a id="objecttype-service"></a>
1357 Service objects describe network services and how they should be checked
1362 > Rather than creating a `Service` object for a specific host it is usually easier
1363 > to just create a `Service` template and use the `apply` keyword to assign the
1364 > service to a number of hosts.
1365 > Check the [apply](03-monitoring-basics.md#using-apply) chapter for details.
