Content planning in a heat wave: Simona and I sat down Monday to map out this week's posts. Nuremberg is currently doing its best to become a Mediterranean city, and our brains were noticeably cooperative for maybe the first half hour. This post is a testament to that

Bernd redeemed the week yesterday with Spaghetti Eis for the whole org. 10/10 management decision.

Our Partner Manager Angelika attended the Stockholm Tech Show this week - and met up with Binero right there on-site.

Binero is our dedicated partner for the Nordics. They bring local presence and hands-on Icinga experience to teams across the region. If you're running Icinga in Scandinavia or looking to get started, Binero is worth talking to!

Building multi-value form inputs in ipl-web? Then the TermInput is worth knowing.

Our Web Developer Bastian published a step-by-step guide covering the full feature set: per-term validation, label enrichment, multipart updates so enriched terms survive auto-submit, and search suggestions via SearchSuggestions.

The walkthrough uses a weekday picker as the running example, which keeps it concrete and easy to follow.

Read the full blog post here:

Learn how to use the ipl-web TermInput to handle multi-value form inputs in Icinga modules with validation, term enrichment, and live suggestions.

Open Source Night in Nuremberg is coming up on June 23, and we're co-hosting it together with NETWAYS as part of the Nürnberg Digital Festival
The evening covers Open Source, Digital Sovereignty, Cloud, and AI - topics that don't need an introduction if you work in IT. Come for the conversations, and stay open to meeting people who deal with the same things you do every day.

One thing worth flagging: the event is in Nuremberg and sessions will be in German.

Food and drinks are on us.

Icinga 2 v2.16.1 is out: a targeted bugfix release addressing a regression in the performance data writers introduced in v2.16.0.



The affected writers - ElasticsearchWriter, GraphiteWriter, GelfWriter, InfluxdbWriter, Influxdb2Writer, and OpenTsdbWriter - had been reworked in v2.16.0. That rework introduced issues that, in some cases, caused Icinga 2 to stop behaving correctly. We are still investigating the root cause. For now, v2.16.1 reverts those writers to their v2.15.3 state to restore reliable behavior for everyone affected.



This release also adds a documentation clarification: the OTLPMetricsWriter for OpenTelemetry is not available on Debian 11, Ubuntu 22.04, or Amazon Linux 2 due to dependency version constraints.

Tomorrow is our next webinar - here's what you'll actually walk away with.

The Terraform Icinga 2 Provider communicates directly with the Icinga 2 API. That means your monitoring objects - hosts, services, check commands, notifications - become versionable, reviewable, and deployable the same way your Terraform-managed infrastructure is.

Bram Vogelaar will cover the complete setup: from authenticating the provider to structuring your Terraform files so monitoring follows new infrastructure automatically. If you've been meaning to bring IaC discipline to your Icinga setup, this session covers exactly the patterns you need.

Date: Tomorrow, May 21, 2026
Time: 3 PM - 4 PM CEST

Over 1,000 Icinga plugins are now in one place: icinga.com/plugins/

Previously, the Icinga Exchange at exchange.icinga.com was the go-to for community plugins - useful, but not always easy to navigate.

We've moved everything over to a dedicated plugins page with filtering by category and vendor.

Whether you need checks for network devices, cloud services, databases, storage, or applications, you can browse by what you're monitoring or by who built it.

That range reflects what Icinga is built for: highly flexible monitoring that fits your stack, not the other way around.

Budget cuts are a real issue for conferences. And community-run open-source events are often the first to feel it.

FrOSCon has been running every summer in Bonn since 2006, organized by the computer science department of Bonn-Rhein-Sieg University together with FrOSCon e.V. Talks, workshops, an open-source exhibition, and a social evening that brings together developers, contributors, and practitioners from across the German-speaking community. Not backed by a large corporate budget. Kept alive by people who show up.

This year, the organizers are short on conference partners. That directly affects streaming infrastructure, event tech, the kids and youth program, and the basics like volunteer catering and transport costs. They're specifically looking for conference partners and a coffee partner.

We're exhibiting at FrOSCon this year. A number of companies have already stepped up: SUSE, Linux Professional Institute (LPI), Bareos, credativ GmbH, TUXEDO Computers GmbH and others.

Events like this don't have to disappear. If your company is either part of the open source ecosystem or profits from it and has room to support a conference that's been going for nearly two decades, it's worth a look.

If your infrastructure is already defined in Terraform, your monitoring config probably shouldn't be the exception.
A lot of teams use Terraform (by HashiCorp ) to provision servers, networks, and cloud resources - but then manage Icinga hosts, services, and notifications by hand. That breaks the consistency you built everywhere else.

On May 21, Bram Vogelaar is running a hands-on webinar on the Terraform Icinga 2 Provider.
He'll walk through the full workflow: provider setup, API authentication, and managing hosts, host groups, services, check commands, users, and notifications - all declared in Terraform config files.

Date: May 21, 2026
Time: 3 PM - 4 PM CEST

How do you handle secrets in Icinga 2 without introducing unnecessary complexity?



This blog post explores several practical approaches for protecting sensitive data in monitoring environments. Icinga's Core Development Lead Julian suggests a lambda based way to secret handling and encrypted systemd credentials.



He also highlights an important question many teams overlook:

Do you even need a password in the first place?

In case you missed it: with v2.16, Icinga 2 can export check plugin performance data as native OpenTelemetry metrics via OTLP HTTP.

That means your infrastructure metrics can flow directly into:

Prometheus
Grafana Mimir
Datadog
OpenSearch
Elasticsearch
VictoriaMetrics
and other OTLP-compatible backends

If you're already using OpenTelemetry for observability, integrating Icinga metrics is now straightforward.

Check out our blog post to learn more and get started:

Icinga 2 v2.16 introduces native OpenTelemetry support with the OTLPMetricsWriter. Export your monitoring metrics to Prometheus, Grafana, Datadog and any OTLP-compatible observability platform.
