Icinga 2 - Configuration
• Different config format
• Won’t miss the old config!
• It is really time for change
• You will love it!
#icinga

Icinga 2 – Configuration - 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 ...
}
#icinga

#icinga
Icinga 2 – Configuration – Assign service using apply
apply Service "ssh" {
import "generic-service”
check_command = "ssh”
assign where host.address && host.vars.os == "Linux”
}

#osmc
Icinga 2 – Configuration – Assign to Hostgroup in the old world
define hostgroup{
hostgroup_name linux-servers
alias Linux Servers
members linux1,linux2,linux3
}

#osmc
Icinga 2 – Configuration – Assign to Hostgroup using apply
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)
}

Icinga 2 – Configuration – Another cool thing
#icinga

#icinga
Icinga 2 – Configuration - Conditionals
• Conditionals – Time dependent thresholds
object Service ”webservice" {
import "generic-service”
check_command = ”load”
host_name = “a really great server”
vars.load_wload1 = {{
if (get_time_period(“9to5”).is_inside) {
return 40
} else {
return 60
}
}}
}
