Icinga 2 - Migration
• Start with a fresh server
• Inventory of plugins & configuration
• Define your configuration strategy with Icinga 2
• Create the best Command and Apply definitions only once
• Only add hosts (and users) in the future
• More migration hints on the docs!
http://docs.icinga.org/icinga2/latest/doc/module/icinga2/chapter/migration#migration
#icinga

Icinga 2 – Migration: Assign service to hosts in Icinga 1.x
define service{
host_name linux1,linux2,linux3,...,linux9
service_description ssh-check
other service directives ...
}
#icinga

#icinga
Icinga 2 – Migration: Apply service to hosts in Icinga 2
apply Service "ssh" {
import "generic-service”
check_command = "ssh”
assign where host.address && host.vars.os == "Linux”
}

#osmc
Icinga 2 – Migration – Assign members to Hostgroup in Icinga 1.x
define hostgroup{
hostgroup_name linux-servers
alias Linux Servers
members linux1,linux2,linux3
}

#osmc
Icinga 2 – Migration – Assign members to Hostgroup in Icinga 1.x
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
Icinga Web 2 - Motivation: Classic UI
• Not extendable
• Lacks real user management
– Authorization based on contacts - not enough for enterprise
needs
• Not usable on mobile devices
• Same machine as core
• Heavy I/O

#icinga
Icinga Web 2 – Motivation: Icinga Web 1.x
• Complicated XML configuration
• Cached configuration
• Framework overhead
• Not useable on mobile devices
• Slow in big environments
• Complicated API

#icinga
Icinga Web 2: Key features
• Lightweight like Classic UI & flexible as Icinga Web 1.x
• Easy to extend and embed into other projects
• Support for multiple authentication providers
– Internal DB
– LDAP
– HTTP Auth
• Support for IDO database & Livestatus
• Supports multiple backends simultaneously, as failover backend
• Responsive actions (tablet, mobile, etc)
• FAST!

#icinga
