3 Agenda Icinga Project Icinga 1.x Icinga 2 Icinga Web 2 Demo Conclusion & Vision

4 THE ICINGA PROJECT

5 The Icinga Project Introduction Open Source Enterprise Monitoring Icinga is a scalable and extensible monitoring system which checks the availability of your resources, notifies users of outages and provides extensive BI data.

6 The Icinga Project About us Originally forked from Nagios in April 2009 Independent, redesigned version Icinga 2 since 2014 Different teams with autonomic responsibilities

7 The Icinga Project - Icinga Exchange

8 The Icinga Project - Icinga Exchange - GitHub

9 The Icinga Project Tools & Platform Icinga Quality, Testing and Community Support Website and Open Source Ticketing System Icinga 2 Icinga Core 1.x Icinga Doc Icinga Reports C++-based source with multiple components C-based source MySQL, PostgreSQL, Oracle based on Markdown based on Jasper Reports IDO Livestatus Cluster IDOUTILS Icinga Web 2 Based on PHP / responsive design Icinga Web 1.x based on PHP using ExtJS, Agavi MVC 3 rd Party Tools

28 ICINGA 2 - CONFIGURATION

29 Icinga 2 - Configuration New configuration format Won t miss the old config syntax! It is really time for change You will love it!

30 Icinga 2 Configuration: Syntax Highlighting Use syntax highlighting! # cd /usr/share/doc/icinga2-common*/syntax # PREFIX=~/.vim # mkdir p $PREFIX/{syntax,ftdetect} # cp vim/syntax/icinga2.vim $PREFIX/syntax/ # cp vim ftdetect/icinga2.vim $PREFIX/ftdetect/ # vim /etc/icinga2/icinga2.conf

31 Icinga 2 Configuration: Console Use icinga2 console to test values, functions, etc! Install rlwrap # yum install rlwrap # rlwrap icinga2 console

32 Icinga 2 Configuration: Value Types Get to know all the value types!

33 Icinga 2 Configuration: Constants PluginDir, MysqlPassword, SnmpCommunity,

34 Icinga 2 Configuration: Templates Templates for generic attributes

35 Icinga 2 Configuration: Custom Attributes Numbers, Strings, Booleans, Arrays, Dictionaries Filters, Match Conditions, additional information

36 Icinga 2 Configuration: Commands Optional/conditional arguments, functions, default values

37 Icinga 2 Hosts and Services Checkable objects and attributes

38 Icinga 2 Configuration: Apply Services Match on (custom) attributes, names (assign) Exclude objects (ignore)

39 Icinga 2 Configuration: Apply For For loops over arrays/dictionaries

40 Icinga 2 Configuration: Notifications Dynamic notification rules

41 Icinga 2 Configuration: Dependencies Host-on-Service, Service-on-Host, Classic Icinga 2 HOST router SERVICE router-uplink Reachable? HOST website-server

42 Icinga 2 Configuration: Conditionals If-then-else

43 Icinga 2 Configuration: Loops While, for and break/continue

44 Icinga 2 Configuration: Type methods & Object Accessors Array#sort, Dictionary#contains, String#find, Object accessors get_host(), get_service(), etc Access config and runtime attributes e.g. get_host(nodename).state

45 Icinga 2 Configuration: Functions Use pre-defined or your own regex(), match(), Custom attributes, command, argument values

46 Icinga 2 Configuration Another cool thing

47 Icinga 2 Configuration Time dependent thresholds Time dependent thresholds

48 ICINGA 2 - MIGRATION

49 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!

50 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... }

51 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 }

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

53 Icinga 2 Migration Assign members to Hostgroup in Icinga 1.x object Host mysql-server1" { address = " check_command = "hostalive } object HostGroup "mysql-server" { display_name = "MySQL Server assign where match("*mysql*", host.name) } #osmc

54 ICINGA WEB 2

55 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

56 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

57 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!

58 Icinga Web 2 - Overview Beta Version: beta3 ( ) Release Candidate: rc1 (late May 2015) Final version: (scheduled for Q2 2015) Supports all major distributions Apache & Nginx support Packages and Vagrant Box available now!
