OpenTelemetry gets talked about mostly in the context of distributed traces. If you're running infrastructure monitoring with Icinga, you might have assumed OTel isn't really relevant to you.
That assumption is worth revisiting.

OpenTelemetry is also a metrics standard - and in 2026, virtually every observability platform accepts OTLP data natively. Prometheus, Grafana Mimir, Datadog, Elasticsearch, VictoriaMetrics, New Relic, Dynatrace, Splunk. That's not a list of specific integrations. That's what "any OTLP-compatible backend" actually means in practice.

With the OTLPMetricsWriter in Icinga 2 v2.16, your check performance data speaks that standard. One configuration object. No separate integrations to maintain for each backend.

On June 30, we show how to set it up end to end and what it means for teams already running Icinga alongside a modern observability stack.

The ?limit= URL parameter in Icinga Web 2 accepts any positive number - including values below the 25-entry floor in the settings panel.

Useful for stacking multiple views in a custom dashboard where you only need the top handful of each. Also for screenshots.

Append ?limit=5 to any list view URL and save it as a dashboard element.

Our developer Jan wrote up this and three other Icinga Web 2 features worth knowing: keyboard navigation, multi-select for bulk actions, and split-pane views via the #! URL separator.

One or two trainee positions are still open at our Nuremberg HQ. The program starts September 1st, run together with NETWAYS.

If you're interested in technology and looking for a practical entry into the field (rather than a purely academic one) this might be the right fit. Some background in software development or monitoring is a plus, but not a requirement. Good German is, though - the vocational school program runs entirely in German.

We're open to applicants from different starting points: finishing school, switching careers, or stepping away from university. As long as you're passionate about tech and open source, we'd be happy to have a chat.

Apply via NETWAYS: https://netways.de/jobs

Blerim's talk from All Things Open Conference 2025 is now live on allthingsopen.org.

Going to All Things Open was one of the better calls we made last year.
As a Germany-based company, Europe is mostly our home base for events. That's why we were curious what the open source community looks like in the US. We had really cool conversations and also came back with actual collaborations, including a cooperation with Learn Linux TV.

The talk itself covers monitoring at scale: rule-based configuration that applies the right checks automatically as your environment grows, a built-in clustering architecture with no third-party dependencies, and a Kubernetes module that uses push-based monitoring from inside the cluster rather than polling from the outside.

Watch this 40 minute video to get to know what Icinga looks like in a 40,000-node environment.

Two of our trainees, Sasha and Alex, just shipped the demotour module to our public demo and it's now live in production.

It's an interactive tutorial that guides users through Icinga Web: the layout, monitoring basics, problem handling, and adding a new host via the Director. The guides are independent and modular, so new tours can be added over time.

They built this mostly independently, halfway through their second year with us. We're super proud of them.

OpenTelemetry has become the common language for metrics in modern observability stacks. Icinga 2 now speaks it natively.

With the OTLPMetricsWriter in v2.16, check plugin performance data is exported as OTLP-compliant Gauge metrics and can be sent directly to Prometheus, Grafana Mimir, VictoriaMetrics, Datadog, Elasticsearch, New Relic, Dynatrace, Splunk, or any other OTLP-compatible backend - with host and service resource attributes attached.

On June 30, we're showing how to configure this end-to-end: from enabling the writer to running it alongside existing Icinga DB and Graphite setups, including HA cluster zone handling.

If your observability stack already speaks OTLP and you want Icinga metrics feeding into it, this session is the practical starting point.

Three plugins cover most of what you need to monitor Docker with Icinga.

1) One checks individual containers - CPU, memory, restart counts, health check results, and whether the running image matches what's in the registry.

2) One watches the Docker daemon itself.

3) One tracks resource usage across all running containers at once, with spike suppression built in.

The new blog post by Blerim walks through each of them, explains where to find the rest of the Docker plugin directory, and covers how Docker monitoring differs from Kubernetes monitoring (and how Icinga handles both from one place).

Monitor Docker containers with Icinga using open-source plugins for CPU, memory, health checks, image drift, and daemon status - integrated into your existing infrastructure monitoring.

Spain's largest insurance group moved from Nagios to Icinga with one clear goal: more agility in how monitoring is managed. The migration ran with both systems in parallel until the old one could be switched off cleanly with no downtime and no gaps in coverage.

Today Mutua Madrileña manages 1,200+ hosts and 20,000 services across a master and two satellites: Linux machines agentless via SSH, Windows hosts, OpenShift clusters, VMware, and Azure all in scope.

Next phase scales to 2,000 hosts and 40,000 services.

"Icinga is now used in all of our daily operations and for quick diagnostics in case of problems it is excellent." Enrique Guerrero Martinez, IT Platform Engineer, Mutua Madrileña

If you're running Citrix and want to know what Icinga plugins cover it, this is the page to check:
https://icinga.com/plugin-vendor/citrix/

The plugins cover NetScaler ADC health via the NITRO REST API, Gateway login and published resource checks, firmware update status, and legacy ICA server uptime for older Metaframe XP environments.

We've added vendor-specific views across the plugin directory, like Citrix, VMware, NetApp, and many more. So you can now easily check what's available for your stack.

The Icinga forum is meant to be humans helping humans. And keeping it that way is important to us, it's what makes the forum actually useful.

After several community members reached out about posts that felt AI-generated, we added a section to the forum guidelines.�
