Livestatus
#osmc
Icinga 2 - Enable Livestatus

#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" {
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
}
