Last week I told Blerim that Icinga came to life on 6.5.2009 … really, 10 years already?

A small group of Nagios community members stood up and wanted to create more than a monitoring core with an enhanced web interface. APIs, integrations, backends, scaling, metrics, … A lot of passion and love was received from the community and actually, the Nagios ecosystem became more active again. We tried many things to improve the existing code base and limitations in both backends and frontends. TL;DR – at some point we decided to throw it away and start fresh. The rest can be read on our blog 🙂

 

service icinga restart

Back in 2012, Gunnar, Bernd and Marius paid a visit to Vienna. They had something with them what is known to be the first prototype of Icinga 2, codename “Strawberry“. Moving from C into C++ was a whole new world, Golang didn’t really exist back then. Oh, it can run on Windows too. Oh, such speed and performance. Oh, a new playground for our crazy ideas.

Before its first 2.0 release five years ago we had many design rounds with service sets on the Host object, virtual host checks from services and so on. This changed quite a bit after strong opinionated discussions in early 2014. Those are also the origin of the magic apply rules, with mimicking the “put a service on a hostgroup, each host member inherits it” object trick from Icinga 1. Nowadays you can generate monitoring configuration and make things easier.

“Monitoring as a code” became a thing when we had created our own DSL (domain specific language) which added functions, conditions, even loops from community feedback. We’ve also learned a lesson here with the Director released after 2.4 – not everything from inline DSL code is suitable for a configuration frontend. Also that we now have 3 APIs – Core, Web, Director – users might be confused. This is a task we will be working on in the future to unite the product stack better.

Speaking of web and modules, Icinga Web 2 started with the requirement of a general framework including web and CLI based on the Zend framework. IIRC this was 1,5 to 2 years after Icinga 2 kicked off, also explaining the version difference – 2.7 vs 2.11. Web version 1 had many short-comings and was complicated with extensions – unless you’re an experienced developer. With the power of making everything a moduie, even monitoring, the Icinga Web framework inspired the many of you.

 

Community work is a passion

One of the first community modules I’ve seen was the Globe module which I had shown at Icinga Camp Berlin 2017. Nicolai was so inspired to start the development of the map module. I was extremely happy that I’ve tested it quite extensively and sent a docs PR. Literally the same happened with Carsten creating the famous Grafana module – a gentle README, release hints and troubleshooting – the first impression counts. Did I mention the awesome themes already?

Pushing community ideas and spirit forward is one of the most important things in the way we have become Icinga. Without you and your shared love and criticism, we wouldn’t be here and still be sitting somewhere around the globe ranting about tools.

Back then, our community was a bit split, and not everyone had the time to answer questions on IRC, the mailing lists and the community forum at Monitoring Portal. While we want to be transparent with our development workflow, release dates and design ideas, it’s always time consuming and hard to catch up. With Icinga now supporting distributed environments with zones, endpoints, and web views and configuration forms, we needed something where text formatting and screenshots really integrate well. In late 2018, we’ve decided to create our own Icinga Discourse inviting the team, partners and users to discuss. I just love it, helping others really is a good feeling.

As you may know, the majority of the Icinga development is and was funded by NETWAYS, up until 2012 the University of Vienna sponsored my time. This is paid time and helps with creating the foundation for new features and maintenance. We also raised awareness on why funding and sponsoring is a good thing – if there is a bug biting you, or a missing feature you’d like to use in production, you can speed things up by requesting a quote, or even, by getting a support subscription through one of our partners. Sounds expensive? Maybe. Helps funding the future? Definitely.

Still, we love community contributions and value your (spare) time a lot. Sometimes contributions are hard to achieve as the code is not clear, or you actually don’t know where to start. In the past, we had our own Git server and ticket system. It worked somehow – with the move to GitHub and social coding with Pull Requests, reviews, discussions and a sound platform our daily work on Icinga has become a breeze. The help of issue templates, continuous integration (CI) on when a PR is created, and inline code comments puts the focus back on development.

Lastly, we’ve started documenting our core technical concepts and improved the development guidelines. This now also includes instructions for nightly snapshot builds.

 

Turning back the time a bit

Icinga 1 didn’t have packages at first glance. You had to call configure/make and pass some parameters for development libraries and headers, sometimes it didn’t work. The core was to compile and then it broke on your system, but the developer’s system worked fine. Ok, let’s create a VM for SuSE in Virtualbox … well, where is my yum?

One of the first ideas was to invite upstream packagers onto the team and learn from each other. Our many releases couldn’t reach stable distributions that fast, so we needed additional repositories. There’s Debian Backports, custom Ubuntu PPAs, EPEL for RHEL/CentOS and lastly, the SuSE OBS repos – not to forget all the other distributions in the Linux/Unix world, FreeBSD, OpenBSD, NetBSD, Gentoo, ArchLinux, … For the main officially supported platforms, we decided to create our own repository at https://packages.icinga.com.

Creating and maintaining packages next to the build infrastructure for each project, language and dependencies is a huge often underestimated effort. Our build server based on Jenkins made several iterations over the years, lately we decided to replace it with GitLab CI for less security risks and better configuration. CI and CD is just great, and with Docker containers nearly everything can be built – requiring your self-hosted infrastructure, maintained by the awesome managed service team at NETWAYS. This includes deployments with Foreman and Puppet, and of course monitoring with Icinga just like “eat your own dogfood” 🙂

Another thing which really was hard to achieve – ARM based architecture on Raspberry Pi. Sounds easy to just compile the binary packages on a different architecture. Actually we had to tackle compiler bugs and long running builds – we started a thing at the OSMC hackathon 2018 and Nicolai’s employer sponsored the last missing days on the road to official packages.

 

We can always improve

Looking back where we started 10 years ago, we’re in a very comfortable situation. This also includes making the initial setup a breeze, adding lots of documentation and helping on the community channels when things are on fire. With partners providing support, trainings and consultancy, the enterprise requirements are fulfilled even better.

In terms of new projects and ideas, it always turns out that we want to create 4 things, then 10 different customer issues arise, the proof of concepts don’t work out well and obviously, there’s only resources for one or two things being released later. Right on, many have asked about notification managers or mobile apps – that’s on hold for now, finishing the ongoing tasks with Core and Web major versions, Icinga DB and Icinga Reporting, and additional new module version for certificates (x509), Vsphere, Director and Business Process. Again, focus is required – you cannot manage 10 things in parallel. That being said, the monthly snap blog will be moved into a combined effort with the enhanced newsletter telling you about the latest and greatest developments. We also continue to have bi-yearly strategy workshops to refine future roadmaps and discuss changes in our ecosystem.

Those things are great to read, but even more, they are great to talk about. Our idea of meeting at Icinga Camps worked out pretty well, Berlin is by far the biggest one thus far. OSMC with the “State of Icinga” talk by Bernd is great and funny way to share the latest stories too. Our first Icinga team meeting was at OSMC 2009 with many more to come at Icinga Camps all over the world, where you’ll meet, chat and laugh. Our first Icinga Camp San Francisco 2014 happened at GitHub HQ. This is an incredible memory and kicked off the many community events after. In the past months, our community in Germany and Austria have been going strong with regular meetups, that’s truly inspiring. Not been there, or want to create your own meetup group? It is not too late.

We are also aiming for something bigger for everyone planning for next year: IcingaConf in Amsterdam in 2020.

Our way of not re-inventing the wheel but building our integrations with proven tools will continue. Today we are proud to enhance Elastic Stack with adding Icingabeat, Logstash outputs/filters and metric writers even. Adding monitoring as first class citizen in your DevOps lifecycle has become reality with official modules for Puppet, Ansible and Chef and a deeper integration into Foreman. If this isn’t enough, there’s more cloud provider integrations such as Terraform, AWS, Azure and whatnot. Enhancing metrics with Graphite and InfluxDB, provided with example Grafana dashboards and web module integrations. Dashing is still a thing, and reporting has come in its first early version for more SLA and visualization magic.

This is something we couldn’t imagine 10 years ago. We are also proud to work with many professionals and open source lovers all over the world, spreading the #monitoringlove.

Many thanks also to Thomas Krenn who sponsored hardware for the initial build server, JetBrains, Navicat, Atlassian & Activestate for granting us open source project licenses back then.

Bernd, Marius and Julian are the remaining co-founders of Icinga. I was a little late to the party in May 2009, with the rest of us enjoying Icinga with our friends, partners and users every day. You’ll recognize Eric for our technical strategy and everything web and core, Blerim improving and managing all the products, helping partners, maintaining integrations, Tom pushing forward with designs and architecture and the shiny Director, VSphere, etc. modules, Markus taking care of QA, tests and the heavy build infrastructure, followed by Director development lately.

Jean moving along from Icinga 2 core into IcingaDB, followed by Noah with passion for Golang. Our UX designer Florian shaping the web in all its beauty, Johannes taking the lead for Icinga Web and many new modules, followed by Feu with her passion for CSS and better frontend widgets. Alex being the Graphite module developer who recently joined the core devs with the major network stack rewrite, helping my duties on leading the core development whilst sharing all the knowledge with our trainee Henrik. Thomas taking care of Icinga support and improving everything around it. Julia joined for spreading the love on social media and events.

The many of you improving the Icinga Template Library (ITL) commands, sending Graphite templates, documentation updates, issues, pull requests, etc.

Our many friends at customers and users who convince their managers to use and support Icinga. And to share the love – publicly talk about it. Whenever a new Audi or VW is built, Icinga watches. Whenever you buy things online, do bank transactions, go shopping, watch TV, use your mobile phone or enjoy life – Icinga takes care that it works. And when you look up the sky, maybe you can spot the ISS with Icinga exploring space.

There are many more great Icinga users, you know who you are. Thank you from our hearts for an incredible journey.

You know, we are party people celebrating after hard work. Say cheers with your favourite drink, I’ll have – obviously – a G&T.

 

 

Monthly Snap October: Icinga Camps and Meetups

We’re in OSMC mode in October which typically means that expectations are high, time is limited and everyone is busy preparing talks, demos, implementing new features … but also fixing things. Icinga 2.10 brings support for namespaces, improved TLS connection performance and much more. Community members tackled some bugs already, 2.10.1 is released and 2.10.2 is waiting for test feedback from the snapshot packages. Also notable – we’ve agreed on writing more technical documentation for Icinga, future 2.11 will bring even more shiny insights.
On the right, you can see a draft from our community channels, how Icinga can be run distributed on ships. We’ve also learned that CESNET is using Icinga 2 and the Director for monitoring their eduroam infrastructure, sharing everything on GitHub too 🙂
Our partner Shadow-Soft wrote about using the official Chef cookbooks, NETWAYS updated the Icinga cloud offering in NWS to 2.10.1 and published the webinar video for adding new satellites and also working with the Icinga Director. If you are in Switzerland, join our partner Linuxfabrik for an official Icinga training in December!
Our first meetup in Salzburg, Austria was a great success – many hours of helping each other and exploring all the things. Rumors tell that other Austrian cities might get involved soon – many thanks to Moritz for organizing 🙂  Icinga Camp Tel Aviv happens on December 17th, make sure to book your flight and ticket!
Thilo looked into Grafana and Graphite graphs embedded into notifications, Gian Paolo went for NetBox and Icinga as MVP. Doing the migration dance from Icinga 1 to 2 is a good thing since 1.x is out of support by the end of 2018. 42ThinkTank did great!
That’s it for October, looking forward to the OSMC week, especially to meet many of you 🙂

Monthly Snap August: Icinga Camp Tel Aviv, OSMC Schedule, Icinga 2 Book & Releases

Our first Icinga Camp Tel Aviv happens on December 17th, 2018, the fourth edition in Berlin takes place on March 14th, 2019 again 🙂
The first Icinga meetup in Salzburg, Austria happens on Oct 12th, 2018 – join for more #icingalove. The Berlin meetup was a great success, Carsten and Lennart joined there too. Watch their meetup group for future dates.
The OSMC 2018 schedule is online, with so many interesting talks in two days on three tracks. The hackathon on the last day is also back for more #icingalove.
Watch out for future Icinga trainings by our partners. There’s a new workshop available by NETWAYS which practices automated setups with Puppet and Icinga.
This month brought many releasesIcinga Web 2.6.1 as bugfix release, Graphite module 1.1 and Director 1.5. Icinga joined the OpenAPM initiative in August, you can learn more about it at OSMC later this year. We’ve also learned that Icinga is now an official input for InfluxDB’s Telegraf.
Carsten released v1.3.0 of the Grafana module for Icinga Web 2. Claudio shared insights into pinning checks in HA enabled cluster zones. Our partner NETWAYS has uploaded their webinar on building an Icinga 2 environment. Bernd updated his blog post series on monitoring tools which includes Icinga (obviously ^_^).
When the Icinga 2 book v2.0 got released, you are doing crazy things …. you’ll pause your vacation and drive 140 km … or you’ll wait and take it with you … sit at home and wait like xmas … compare the size, it is huge … feel motivated in a new week … and just love it.
Nagstamon turned 10 this month, cheerio ? Gunnar provided a patch for Icinga 2 which adds references, crazy shit. The monitoring plugins team and community members are working on check_curl replacing check_http at some point. Why would time be wrong, monitored with Icinga? 😉
Thank you Sascha for the nice view with the Icinga 2 book!

We've come a long way together … Icinga turns 9

Born to be wild

We’ve been busy with bringing Elasticstack integration into full shape with the Icinga 2 feature and the corresponding Icinga Web 2 module. Both of them were thankfully funded and sponsored by VW. Elasticsearch 6 support is sponsored by a customer too, this will hit 2.9 later in June. Earlier in 2017 we’ve also released the Logstash output for Icinga.
Another integration is Graphite. Shiny metrics available for problem analysis and correlation directly integrated into the host/service detail view in Icinga Web 2 are now a breeze. There’s also a feature rich template language available which makes customization a breeze. And in case you’ll need an overview dashboard, that’s the icing on the cake.
Want to kick off your own module? Look into the existing modules and peek into Eric’s showcase module. Expect more insights into Icinga Web 2 modules and also the theming in the future 🙂
