Icinga2 | dependencies

| Written by vincent | Print | Email | Hits: 5758

Icinga2 | dependencies

Imagine, you have a Switch with 3 NAS on it - the NAS are not often used and Switched off like the Switch itself.
so
the Host-Check to the NAS should only be when Switch is on and hostalive!
the NAS-Service-Check should only be if the NAS ist up = hostalive!

#  cd /etc/icinga2/conf.d
#  mkdir dependence
#   cd dependence
#   vi switch2nas.conf
object Dependency "switch2nas" {
    parent_host_name = "swt-03.kozo.ch"

    child_host_name = "NAS-01.kozo.ch"
    child_host_name = "NAS-02.kozo.ch"
    child_host_name = "NAS-03.kozo.ch"

     states = [ Up ]

     disable_checks = true
       disable_notifications = true
 }
   Go to the Host you wish to add the dependency

This will by a Host - Host dependency
if the Switch swt-03 is down 
the NAS-01 get unrechable marked

object Dependency "nas-01-swt-03" {
     parent_host_name = "swt-03.kozo.ch"
     child_host_name = "NAS-01.kozo.ch"
      states = [ Up ]
      disable_checks = true
      ignore_soft_states = true
     disable_notifications = true
 }

  
       
       
       
       
       
       
       
  #   icinga2 daemon -C    
  #   systemctl reload icinga2    
  #   systemctl status icinga2

Icinga2 | add service to a hostgroup

| Written by vincent | Print | Email | Hits: 4435

add a service to a hostgroup

i have a couple of Debian 9 "Server/Host/Client" they all should have some Basic Service Check like (apt, disk, mem, swap, procs, users, running_kernel, apt, ssh, iostat, ping4, fping4, tcp, udp, ssl, ntp_time)

because i don't want to add this check to each host  i did define a hostgroup and add the hostgroupname to the host (--> "define Hostgroup & add Host to a Hostgroup")

 Merci to rsx (Roland) 

 steps i have done... icinga2 Master
 went to the zone.d #  cd /etc/icinga2/zones.d/
 crate a new directory #  mkdir services
 went to the new directory #  cd /services
or #  cd /etc/icinga2/zones.d/services
open a new file # vi service2debian9.conf      
to check apt on all defined Debian 9 "Host/Server/Client" apply Service "apt" {
  import "generic-service"
  check_command = "apt"

  assign where host.address && host.vars.os == "debian9"
  command_endpoint = host_name
 }		      
to Check swap apply Service "swap" {
  import "generic-service"
  check_command = "swap"

  assign where host.address && host.vars.os == "debian9"
  command_endpoint = host_name
 }		      
 Check it if it for error #  icinga2 daemon -C      
if ok #  systemctl restart icinga2      





---

 Sometimes all would be perfect but a Service is on a Host not needed or not available.
so you will get a error.
to avoid the error - just ignore the host like this

 32 apply Service "swap" {
33 import "generic-service"
34 check_command = "swap"
35
36 assign where host.address && host.vars.os == "debian9"
37 ignore where host.name == "memoryalpha.kozo.ch"
38 command_endpoint = host_name
39 }		      
  #  icinga2 daemon -C      
  #  systemctl restart icinga2

Define a Hostgroup Debian
