User story: Bachelor thesis on Icinga 2

We’re busy developers always trying to help on our community channels (mailing lists, forum, IRC) whenever possible. Some users just ask one question, others stick around and get into detail. One of them was Benjamin asking lots of questions about Icinga 2 HA clusters and clients. We exchanged several private messages and emails and it turned out that he is studying Information and Communication Technology at the University of Applied Sciences Leipzig and was writing his bachelor thesis on the Icinga 2 Migration at Deutsche Telekom Technik (in German).

I kindly asked him to share his bachelor thesis as we love to see how Icinga 2 is used and evaluated in user and enterprise environments. Benjamin did send it this week, enjoy reading :) Note: The content copyright is held by the author only.

ICINGA in Action: Monitoring En Mass at Audi, Germany


Audi was in search of an infinitely scalable and flexible monitoring system, which could easily be distributed for high availability. They chose Icinga and its customizable Icinga Web interface, even inspiring configuration addon along the way.

In Audi’s state of the art manufacturing facilities, components with unique IDs move between multiple assembly lines to meet their counterparts ‘just-in-time’. Synchronizing these alongside robot arms and human hands that create their customized cars is a wonder of millisecond accurate coordination. Monitoring it all is no walk in the park.

The project would require the proprietary Tivoli system to be replaced, and monitor 10,000+ hosts and over 50,000 services distributed over 4 sites. Not only was Icinga implemented in a failover setup, but to tackle the configuration of the mammoth monitoring environment LConf was also born.

Icinga in Action: Keeping CERN’s Large Hadron Collider (LHC) on Track, Switzerland/France

Icinga in Action_CERN Icon

Not too long ago, CERN and their Large Hadron Collider (LHC) made scientific history when they found the elusive Higgs Boson. It just so happened to be, that behind the scenes Icinga was quietly monitoring away.

Deep under the Franco-Swiss border, the 27km LHC ring collides subatomic particles travelling at 99.9999991% the speed of light; producing more than 25 petabytes of data annually in the process. Along the ring, detectors at four sites capture this data for experiments – ones which seek to discover the origins of matter and anti-matter, extra dimensions and of course the famed Higgs Boson.

At three of these four sites, Icinga has replaced Nagios to monitor thousands of hosts and services, improving check latency with the help of Mod Gearman along the way. We’re proud to say, Icinga helps make sure that CERN’s LHC is on track.

Team Icinga thanks Christophe Haen, Experiment Online System Expert at CERN LHCb for sharing their monitoring story.

Icinga in Action: Keeping Arthropods Alive at INBio, Costa Rica

Just 1 and 1/2 years old, Icinga is getting around and being used to do all sorts of interesting monitoring things. Icinga friend, Herson Esquivel Vargas shared a bit about how Icinga helps to keep  plant and insect species alive at Costa Rica’s National Biodiversity Institute (INBio).

The private research and biodiversity management centre houses a large and precious collection of biological specimens. Maintaining optimal temperature and humidity is essential to their conservation. In the past, this was done manually by staff with thermostats and paper charts.

Now as part of a pilot study, INBio has implemented Icinga, combined with TEMPerHUM temperature and humidity sensors and Sheeva-Plug computers to take over the environmental monitoring work. Along the way, Herson wrote a Sheeva plugin for this task, which he has made available at INBio’s subversion server svn://

In so doing, Icinga has helped to keep the diptera (otherwise known as flies) at INBio in good condition. Check out the full story and Herson’s paper (English & Spanish by request) on the experiment.
