Icinga is 5 years old!

Today we celebrate Icinga’s 5th birthday and 5 incredible years. We have come a long way from a young fork in 2009, with aspirations to improve upon Nagios. Today we are at the cusp of releasing a complete rewrite, Icinga 2 beta and a new-concept interface Icinga Web 2 – all while maintaining progress on the Icinga 1.x branch.
It is no surprise then that we clocked up over 4800 commits in the last year and doubled in number of contributors. These included nine milestone releases of Icinga 2, and three Icinga 1.x stable releases. Along the way, Icinga 2 has made it to “Icinga 1.x / Nagios drop-in replacement” status, boasting a new object-based configuration format, built-in cluster capabilities and convenient integration with Graphite, Livestatus-based addons.
Development in Icinga 1.x was also active, with improved interoperability and performance in the Core and Web, adding Classic UI live search and click filtering as well as a new Web cronk menu and ‘problems’ views. For these enhancements, we thank the many community contributors who sent in patches, bug reports and feature ideas.

Icinga 5th birthday

In fact, community creations have come in all forms this past year- from the very first books on Icinga published in English and German to RIPE’s Atlas probe with Icinga and Pager Duty’s Icinga notification services.
Our 5th year also brought important changes to our community channels. We moved all our release downloads to Github, migrated our user, development and announcement mailing lists to lists.icinga.org, and created a new auto-built package repository at packages.icinga.org.
In between these activities and development on Icinga 1.x, Icinga 2 and Icinga Web 2, we somehow managed to make it to a couple of events. We headed over to Brighton for FLOSSUK and London for DevOps Days; joined Chemnitz Linux Days and the OSMC, and got together for a team meet-up at the Linux Hotel.
Looking back, this past year may have been the busiest yet. All this activity has certainly attracted the attention of larger organisations such as the carmaker Audi, who implemented Icinga to monitor a whopping 10,000+ hosts and 50,000 services.
Such environments speak for the maturity of Icinga as a project and we are proud to have made it this far in just 5 years. So on this special day, we’d like to say thank you to all our Icinga friends: You have no idea how your mailing list and forum posts; tweets and likes; feature and patch submissions have helped make Icinga what it is today.

Team Icinga welcomes…

… 6 new (including a couple old) members officially to the team!
From helping create Icinga 2 and Icinga Web 2 to continuing Icinga 1.x development, packaging and testing, we sure are glad to have the extra hands on deck.

Icinga 1.11 Released!

Download_Icinga1.11In true parallel development style, this week we bring you two releases – Icinga 2 v0.0.8 and today’s Icinga 1.11.

Download Icinga 1.11 off our new Github repo or use packages to enjoy improved usability and interoperability in the user interfaces, plus performance tweaks in the Core and IDOUtils.


Icinga Web v1.11 requires IDOUtils from Icinga Core v1.11 due to new queries on, and database fields in the IDO.


Usability enhancements were in no short supply in the Classic UI this time round. From additional modified attribute filters, group notes and action URL links, to a suite of logos for host and service icons, as well as support for gzip compressed logs, much inspiration was drawn from our user community.
We also thank our users for their contributions to the Core – Philip Matuskiewicz, Franky Van Liedekerke, Marco Hoyer, Tomas Dubec, Laurent Bigonville. These include new commands to enable and disable freshness checks by host or service; service escalations without host mapping and passive check-result processing corrections. An option for anonymous external command users in the logs has been added, and brings Icinga up to speed with data retention laws.
Interoperability was improved in this release, especially in IDOUtils’ use with Solaris and Oracle, and Icinga Web’s consistent operation across all browsers (including IE) thanks to an upgrade to ExtJS Icinga Web also features jump links from performance views to the related host and services, alongside a reload progress bar including caching as well as static macro expansion for {action,notes_url} (thanks Immobilienscout24 for sponsoring these 2 features!) and changes to guarantee uniformity in time zone handling.
See the full change logs  for more, and download Icinga 1.11 while you’re at it. Should you come across a bug or idea for a good new feature, do not hesitate to share on our development tracker and feedback channel. Even better, hop on our dev mailing list to chat – we’re looking for Icinga Reporting buffs for future releases. Thanks again to all those who contributed their bit to Icinga 1.11!

Icinga 2 v0.0.8 Released with Redesigned Dependencies

Download_Icinga2We tick off another feature to simplify configuration in Icinga 2 with our latest release, v0.0.8. Say goodbye to confusing array-attribute style dependencies. Version 0.0.8 allows you to configure dependencies as inline dictionaries in service objects (just like notifications, scheduled_downtimes, etc) and assign multiple attributes directly. Just as in Icinga 1.x, you can configure checks and notifications to be executed dependent on state type and time period. On top of the familiar attributes, we’ve added ‘disable_checks’, ‘disable_notifications’, ‘state_filter’ and ‘period’. Please note that we have departed from the ‘dependent’ identifier of Icinga 1.x to use ‘parent_{host,service}’ and ‘child_{host,service}’ instead. We hope this will save users the confusion associated with the Nagios-inherited configuration style.
Alongside new dependency objects, we’ve extended Icinga 2’s clustering capabilities with improved performance, recursive ‘config includes’ and a cluster and instance health check. Furthermore a dedicated feature for dumping the current status of Icinga 2 and all of its features to a status JSON file has been added. But there’s a lot more in our new release than that – see our Icinga 2 change log for details. Also, please be sure to update your configuration in terms of changed dependencies and upgrade the database schema in the IDO database backend.
Get started with these new features by taking a look at our straightforward guides in our Icinga 2 documentation. Visit our support channels for help if you need, and let us know what you think of our latest new capabilities via our feedback and development tracker.
Wait no longer – download Icinga 2 v0.0.8 now.

  • Add optional IcingaNodeName for cluster feature
  • Populate check_source attribute with the checker’s node name
