I will describe how i did install the check_nwc_health plugin

to use spez Plugin i have a spez directory (--> Icinga2 | (spez)Plugins | define path)

Step	on the Icinga2 Master
	# cd /usr/lib/nagios/pluginsCustom
	# mkdir check_nwc_health
	# cd /usr/lib/nagios/pluginsCustom/check_nwc_health
	# cd /tmp
	# wget https://labs.consol.de/assets/downloads/nagios/check_nwc_health-7.1.tar.gz
	# tar -xvzf check_nwc_health-7.1.tar.gz
	# cd /check_nwc_health-7.1
	./configure
	make
	mv plugins-scripts /usr/lib/nagios/pluginsCustom/check_nwc_health

Icinga2 | add service to a hostgroup

Created: 27 July 2018 | Written by vincent | Print | Email | Hits: 5142

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

Created: 21 July 2018 | Written by vincent | Print | Email | Hits: 7064

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
