Perfect
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 |

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 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
