Icinga Notifications has reached 1.0. If you’ve been testing the 0.x versions, this is the release that’s ready for production. 👇

Since then it has gained HA support, a versioned API, secure connections, delivery feedback for every channel and a new Telegram channel. Schedules, rotations and escalations are all managed in Icinga Notifications Web, and day-to-day incident work happens in Icinga DB Web, where you already work.

Two things to know before you upgrade: 1.0 is a breaking release, so read the upgrading guide first, and it needs Icinga 2 v2.16.6, Icinga DB 1.6.0 and Icinga DB Web 1.5.0.

Feedback is welcome on GitHub or community.icinga.com.

Take a close look at this picture. Somewhere in it is a small hint at what you could win in our game during the lunch break at OSMC. 👀

Yes, we’re in packing mode. Booth setup, merch and everything else is almost ready, and OSMC is just around the corner.

Are you coming this year? Let us know and visit our booth.

⚠️ Icinga 2 v2.16.6 and v2.15.7 and Icinga Web v2.14.1 and v2.13.2 are out. All four releases fix security issues, so we recommend upgrading as soon as possible.

The most severe ones:

Icinga Web: the standalone chart endpoints let attackers read files and overload the server without logging in. We removed the endpoints entirely.
Icinga 2: the default mail notification scripts allowed command line argument injection through the recipient email address. With GNU mailutils, this can lead to arbitrary command ex*****on.

The releases also fix API issues that could crash the daemon or expose objects users shouldn’t see, plus log injection and a few privilege problems in Icinga Web.

Icinga Web v2.12 and earlier receive no fixes. If you’re still on one of those, move to v2.13.2 or later.

Thanks to everyone who reported these issues responsibly, including Alessandro Mizzaro of Sonar, moreamazingnick, and archnexus707.

Retired clusters used to stay in Icinga for Kubernetes forever. Not anymore.

Since v0.3.0, several clusters can write into one shared database. But when a cluster was torn down, its last known pods, nodes and other resources kept showing up in the web interface. The only fix was deleting rows by hand.

The main branch now has --remove-cluster. Stop the instance, look up the cluster UUID, and run one command. The cluster and all its data are then removed from the database. It doesn’t need a kubeconfig, because the cluster is usually already gone.

It will ship with the next release, and it’s part of our work toward v1.0. If you run several clusters against one database, we’d like to hear how the removal works on your setup.

Johannes explains how it works and how to try it.

With so much attention on observability right now, it's easy to treat monitoring as less important. In practice, many enterprises run both. The harder question is where the line between them sits and who owns what on each side. That's what we'll discuss in tomorrow's webinar.

Status monitoring covers what can't be instrumented: switches, storage appliances, VMware, UPS and PDUs, and the application nobody can recompile. Observability goes deep into application behavior. Each comes with its own config ownership, its own review process and its own recurring cost in engineering hours.

On October 27, Kris Buytaert and Blerim Sheqa walk through both from the operational side, including what changes once an environment grows from 50 to 5,000 hosts.

Did you know Icinga can also monitor software versions?
Let’s take PHP, as a completely randomly chosen example. 👀

The php-version check from Linuxfabrik reads the installed PHP version on the host and compares it with the release data from endoflife.date.

Add --check-patch and it goes WARNING as soon as a newer patch release for your version is available. That’s handy when, say, a fix ships on short notice.

By default it also warns 30 days before your version reaches end of life. You can move that window with --offset-eol, and --check-minor and --check-major are there if you want to know about bigger upgrades too.

Happy monitoring!

We’re looking for Icinga for Windows users who want to help shape what comes next!

The Icinga Insiders are a group of Icinga users who test new features and updated interfaces before they’re released. Every now and then, members get an invitation to a usability test or a short survey.

Our next round focuses on Icinga for Windows, and this time it goes beyond testing. There will be calls and presentations with the developers of Icinga for Windows, so you can see what they’re working on, ask questions, and talk through your setup with the people who build it.

If Windows hosts are part of your monitoring, your day-to-day experience is exactly what we need to hear about.

"Is it up?" and "Why is it behaving like this?" are two different questions. In most environments, they're answered by two different tools.

Status monitoring tells you that a host, service or device is in a certain state and alerts the right people. Observability helps you explore why a distributed application behaves the way it does. One doesn't replace the other.

With so much attention on observability right now, it's easy to treat monitoring as something you migrate away from. In practice, many enterprises run both. The harder question is where the line between them sits and who owns what on each side.

That's what Kris Buytaert, DevOps and open-source expert, and Blerim Sheqa, COO at Icinga, cover in our webinar. If your team is facing exactly that question, bring it to the live Q&A.

Our review campaign starts soon. Write a personal review of Icinga on one of the platforms, and we’ll send you a goodie bag with your choice of a T-shirt in our new design or a towel.

Why we’re asking: the way people find software has changed. Google AI Overviews and AI tools like Claude and ChatGPT now cite review platforms, and that shapes much of what teams see before they ever reach a website or a documentation page. Reviews from people who run Icinga in production carry more weight there than anything we could write about ourselves.

The details, including how to get your goodie bag, will go out in the next few days. To make sure you don’t miss them, subscribe to our newsletter.

P.S. Monitoring we can do. Ironing, not so much. ;)

Some questions usually end up in a GitHub issue or a forum thread. If you’d rather ask in person, come to the Open Source Monitoring Conference in Nuremberg.
The 20th edition of OSMC runs November 17-19, and we’re a Gold Sponsor.

At OSMC 2026, you can ask your questions directly, because the developers behind Icinga will be at our booth.
Maybe your apply rules don’t behave the way you expected, or you’re planning a distributed setup, or you want to talk about OpenTelemetry export or Icinga for Windows. Bring it along!

Just stop by. If you want guaranteed time with the team, email [email protected] to book a slot. That way, we can make sure the right person is there to answer your question.
