icinga: icinga object types

In Icinga2, “objects” are fundamental components that represent various elements and configurations within the monitoring environment. They form the core building blocks of the Icinga2 configuration system.

List of Icinga2 objects types

Below is a table summarizing the types of objects in Icinga2, along with a brief description of each to help you understand their roles and functionalities within the Icinga2 monitoring framework:

Below, I'll provide an example for each object type in Icinga2 configuration format. These examples can serve as templates or guidelines for setting up various aspects of the Icinga2 monitoring system.

1. Host

object Host "example-host" {
  import "generic-host"
  address = "192.168.1.1"
  check_command = "hostalive"
}

2. Service

apply Service "ping" {
  import "generic-service"
  check_command = "ping4"
  assign where host.address
}

3. CheckCommand

object CheckCommand "check-disk" {
  command = [ PluginDir + "/check_disk" ]
  arguments = {
    "-w" = "$disk_warn$"
    "-c" = "$disk_crit$"
    "-p" = "$disk_partitions$"
  }
}

4. Contact

object User "admin" {
  import "generic-user"
  display_name = "Admin User"
  email = "admin@example.com"
}

5. ContactGroup

object UserGroup "admin-group" {
  display_name = "Admin Group"
  members = [ "admin" ]
}

6. TimePeriod

object TimePeriod "work-hours" {
  display_name = "Work Hours"
  ranges = {
    "monday"    = "09:00-17:00"
    "tuesday"   = "09:00-17:00"
    "wednesday" = "09:00-17:00"
    "thursday"  = "09:00-17:00"
    "friday"    = "09:00-17:00"
  }
}


7. User

object User "web-admin" {
  import "generic-user"
  email = "webadmin@example.com"
}

8. UserGroup

object UserGroup "web-admins" {
  display_name = "Web Admins"
  members = [ "web-admin" ]
}

9. Notification

apply Notification "mail-service" to Service {
  import "mail-service-notification"
  user_groups = [ "admin-group" ]
  assign where host.vars.notification.mail
}

10. HostGroup

object HostGroup "linux-servers" {
  display_name = "Linux Servers"
  assign where match("linux*", host.vars.os)
}

11. ServiceGroup

object ServiceGroup "web-services" {
  display_name = "Web Services"
  assign where service.name in [ "http", "https" ]
}

12. Dependency

object Dependency "web-db-dependency" {
  parent_host_name = "db-server"
  child_host_name = "web-server"
  disable_checks = true
}

13. Zone

object Zone "master-zone" {
  endpoints = [ "master1", "master2" ]
}

14. Endpoint

object Endpoint "master1" {
  host = "master1.example.com"
}

15. ApiUser

object ApiUser "api-client" {
  password = "secret"
  permissions = [ "status/query", "objects/modify/*" ]
}

16. ScheduledDowntime

object ScheduledDowntime "downtime-for-maintenance" {
  author = "admin"
  comment = "Scheduled maintenance"
  ranges = {
    "monday" = "00:00-02:00"
  }
  assign where host.name == "example-host"
}

17. Template

template Host "generic-host" {
  max_check_attempts = 5
  check_interval = 5m
  retry_interval = 1m
}
Each example provided is formatted for direct use in your Icinga2 configuration files, allowing you to adapt them to your specific monitoring needs and scenarios.
