Icinga2 | add service to a hostgroup

Created: 27 July 2018 | Written by vincent | Print | Email | Hits: 5251

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
