ICINGA 2 - CONFIGURATION


#osmc

Icinga 2 - Configuration

• Different config format

– there is a conversion script!

– but you won’t miss the old config!

• It is really time for change

• Could be that you hate it now, but you’ll love it later!

• See it in action!


#osmc

Icinga 2 - Assign a service to multiple hosts in the old world

define service{

host_name linux1,linux2,linux3,...,linux9

service_description ssh-check

other service directives ...

}


#osmc

Icinga 2 - Assign a service to multiple hosts in the new world

apply Service "ssh" {

import "generic-service"

check_command = "ssh“

assign where host.address && host.vars.os == "Linux“

}


#osmc

Icinga 2 - Assign to Hostgroup in the old world

define hostgroup{

hostgroup_name linux-servers

alias Linux Servers

members linux1,linux2,linux3

}


#osmc

Icinga 2 - Assign to Hostgroup in the new world

object Host “mysql-server1" {

address = "10.0.0.1“

check_command = "hostalive“

}

object HostGroup "mysql-server" {

display_name = "MySQL Server"

assign where match("*mysql*", host.name)

}


#osmc

Icinga 2 - Assign to Hostgroup in the extended new world


address = "10.0.0.1“


vars.test_server = true

}


address = "10.0.0.1“


}

object HostGroup "mysql-server" {

display_name = "MySQL Server"

assign where match("*mysql*", host.name)

ignore where host.vars.test_server

ignore where match("*internal", host.name)

}


#osmc

Icinga 2 - One more thing


#osmc

Icinga 2 - Working with arrays

object Host "localhost" { check_command = "hostalive“ address = "127.0.0.1" vars.http_vhosts["http"] = { http_uri = "/“ } vars.http_vhosts["Icinga Web 2"] = { http_uri = "/icingaweb“ } } apply Service for (http_vhost => config in host.vars.http_vhosts) { check_command = "http“ vars += config assign where host.vars.http_vhosts }
