If you write Java, Python, Node.js, or .NET, you have been able to add OpenTelemetry to an application without editing its code for years: attach an agent at startup and telemetry starts flowing. Go has been the exception. A Go program compiles to a single static binary with no runtime to hook in...
In case you missed it: OpenTelemetry (OTel) has officially achieved CNCF graduated status! It now stands proudly alongside amazing open source projects such as Kubernetes and Prometheus, to name just a few. It’s been a long journey, and we’re very excited… But, now what? To understand where we’re...
The OpenTelemetry Spring Boot starter gained declarative-configuration support starting in version 2.26.0 — the same YAML schema the Java agent introduced in late 2025, now embedded inside application.yaml. This post traces what one env var, OTEL_SERVICE_NAME=petclinic, does in that new world, an...
Why OpenTelemetry for Dart and Flutter? Dart is a full-stack language and the language of Flutter, one of the most popular frameworks for building cross-platform applications. Data shows over 20% of current app store submissions are Flutter apps. Dart is null safe and type safe, compiles to fast...
There’s a pattern I’ve seen across many teams adopting OpenTelemetry, and it’s well-intentioned every single time. An engineer wants to make things easier for the team. They build a thin abstraction over the OTel API — an IMetric interface, a TelemetryHelper class, a MetricsWrapper module — and s...
On June 12, 2026, the OpenTelemetry Specification project merged PR #5138, deprecating OpenCensus compatibility requirements in the specification. This change updates the specification to match where the ecosystem already is: OpenCensus has been archived since July 31, 2023, and the OpenTelemetry...
Phase 1 of OTel-Arrow established OTAP, the OpenTelemetry Arrow Protocol, as an efficient transport protocol for OpenTelemetry. Apache Arrow is a language-independent, columnar in-memory format designed to move and process structured data efficiently across systems. We demonstrated that telemetry...
Today, the Cloud Native Computing Foundation (CNCF) announced that OpenTelemetry has graduated. Graduation is an important milestone for the project and reflects the strength of the OpenTelemetry community and ecosystem. Since the merger of OpenTracing and OpenCensus, thousands of contributors, m...
OpenTelemetry is gaining traction in manufacturing and other legacy environments as organizations explore modern observability approaches. However, applying these practices in traditional systems introduces a different set of security challenges. The constraints of legacy infrastructure fundament...
Your AI agent just took 45 seconds to answer a simple question. Was it the model? A slow tool call? A retry loop? Every time an application calls an LLM, a chain of model calls, tool invocations, and token exchanges happens behind the scenes — and without observability, you are guessing. The Open...
It’s not uncommon for end users adopting OpenTelemetry to, at some point in their journey, ask themselves: “Why is this stuff so complex?”. Full adoption normally requires understanding the different ways of configuring SDKs, multiple Collector deployments, data pipelines, instrumentation librari...
OpenTelemetry is vast. The Java agent alone includes over 240 different auto-instrumentations. The Collector has hundreds of components. Python, JavaScript, Go, and .NET each have their own ecosystems of instrumentation libraries, each with its own patterns and conventions. In our 2025 Developer...
This report presents findings from the OpenTelemetry Japanese Community Survey, conducted to understand the current landscape of OTel awareness, adoption, and community engagement among developers and engineers in Japan. The survey targeted practitioners across roles such as development, SRE, Dev...
On March 19, 2026, the OpenTelemetry Specification project merged PR #4938, deprecating OpenTracing compatibility requirements in the specification. This change updates the specification to match where the ecosystem already is: OpenTracing has been archived for years, and new integrations are exp...
The Developer Experience SIG is publishing a series of blog posts featuring real-world OpenTelemetry deployments from companies across different industries and scales. This post features Skyscanner, a global travel search platform based in Edinburgh, Scotland. With 1,400 employees worldwide runni...
The OpenTelemetry community accepted the donation of the OpenTelemetry PHP Distro project. This post summarizes what the donation enables, how it relates to existing PHP instrumentation paths, and where contributors can help next. Why this donation matters OpenTelemetry provides a common observab...
When incidents are active, traces usually tell you that something is wrong. The harder problem is figuring out who is affected and why, quickly. OpenTelemetry eBPF Instrumentation (OBI) v0.7.0 adds HTTP header enrichment so spans can carry request context like tenant or user segment. That context...
As part of an ongoing series, the Developer Experience SIG interviews organizations about their real-world OpenTelemetry Collector deployments to share practical lessons with the broader community. This post features Adobe, a global software company whose observability team has built an OpenTelem...
Since OpenTelemetry first introduced Profiles, momentum has only grown towards building a unified industry standard for continuous production profiling, standing alongside traces, metrics, and logs. Today, the Profiling SIG is proud to announce that the Profiles signal has officially entered publ...
Following a donation from Embrace and a call for contributors, OpenTelemetry now has a Kotlin SDK in active development. The project is looking for contributors and folks who are interested in using the library in their application. Why launch OpenTelemetry for Kotlin? Kotlin Multiplatform (KMP)...
OpenTelemetry provides the tools and standards to collect metrics, logs, and traces from applications and services. Getting started with contributions can feel overwhelming, so here are some lessons from hands-on experience. Most guides explain how to find a “good first issue,” fork a repository,...
At the beginning of 2025, the OpenTelemetry Developer Experience SIG published the results of its first community survey. One of the strongest themes was clear: teams want more real-world examples of how the OpenTelemetry SDKs and the OpenTelemetry Collector are actually used in production. To he...
OpenTelemetry is deprecating the Span Event API. This post explains why we’re making this change, what it means at a high level, and how you can prepare. In short: We want to remove confusion and duplication caused by having two overlapping ways to emit events: span events and log-based events. N...
