What is Icinga 2?• Monitoring solutions and what they do

• Individual systems• Network infrastructure• Applications and processes• anything that can return a value via command line

• Open source• Nagios and the Icinga fork• Extensible and scalable

My relationship with Icinga 2

• Replacement for outdated web application

• Proof of Concept through Icinga 2 beta

• Configuration and development

• Enjoyed quiet evenings together

Fantastic! ...how does it work?

How does Icinga 2 work?• Command line interface (CLI) configuration• Hosts, Templates, Groups, Services, &

Commands• plugins and check commands• Monitoring Plugins Library

• snmp, http, nrpe, and more• hostalive checks through pinging• options, so many plugins

• write your own plugin• bash, python, php, perl, etc.• adapt a plugin

What does it look like?

Configuration Samples

# lab printers. put em here.

object Host "Benson Lab Printer" { import "printer" address = /*insert DNS/IP address*/

vars.type = “Lab Printer”}

template Host "generic-host" { max_check_attempts = 3 check_interval = 1m retry_interval = 30s

check_command = "hostalive"}
