Icinga2 | add service to a hostgroup

| Written by vincent | Print | Email | Hits: 5143

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

Icinga2 | define Hostgroup & add Host to a Hostgroup

| Written by vincent | Print | Email | Hits: 7065
Define a Hostgroup Debian
for all your Debian 9 client and Server		  #  vi /etc/icinga2/conf.d/groups.conf   object HostGroup "debian9" {
display_name = "Debian 9"

assign where host.vars.os == "debian9"
}		  
         
add definition to a Host #  cd /etc/icinga2/zones.d/master/ open your hostfile endig with *.conf object Host "client.kozo.ch" {

check_command = "hostalive" //check is executed on the master
display_name = "client name text"
address = "10.147.42.63"
vars.os = "debian9"

vars.client_endpoint = "name" //follows the convention that host name == endpoint name
}		  
         
do a check if it is OK #  icinga2 daemon -C      
and if OK - restart #   systemctl reload icinga2      
-

NOW --> add service to a hostgroup
