Meet five practitioners who attended KubeCon + CloudNativeCon Japan 2026. They share how they discovered #OpenTelemetry, what observability means to them, and which telemetry signals they turn to.
What I would do: keep the metadata-only default, sample full content plus every failed run, and keep content-heavy traces for days, not months.
Which question do you need full prompts in a trace to answer?
Since 14 Oct, @anthropic.com exports Claude agent traces over @opentelemetry.io : each turn, model call and tool use is a span, holding up to 0.75 MB of prompts and responses on Full content.
A new observability bill. Decide what you will query before you store it.
Using more AI and adding lots of contributions, but not understanding the project, will not scale in the long term. #OpenTelemetry, like other #OSS and cloud native projects, is looking for contributors who care about the ecosystem and genuinely want to learn and support the project.
Are you interested in #Otel?
This session is a great fit for you. @jgomezselles.bsky.social, VictoriaMetrics #Cloud lead and #OpenTelemetry contributor, presented “Practical guide on OpenTelemetry Manual Instrumentation (or how to produce clean Observability by getting your hands dirty)”.
Name your span attributes with the OpenTelemetry gen_ai conventions, like gen_ai.request.model. Same names across every service is what lets you correlate one trace end to end instead of guessing.

Claude Platform now exports OpenTelemetry traces (public beta) from Managed Agents, the Messages API and SDKs: every turn, model call and tool use, with latency and tokens.
Best part: agent spans sit in the same trace as the rest of your stack.

Tail sampling cuts what you store, but your own Collectors still receive every span.
The memory they need is arrival rate x decision window x bytes per trace.
Why a tail sampler has to hold every trace before it can drop any, in The Harder Distributed System #3.
DigitalOcean has launched Insights in public preview: OpenTelemetry observability for cloud infrastructure and AI agents in one plane, tracing a single agent turn from model call through every tool invoked. Will cloud telemetry replace external suites?
Cloudflare’s new Traces open beta adds OpenTelemetry spans for security rules, transformations, caching, routing, and origin handling, with W3C trace context propagation and targeted sampling through Trace Rules.

Am I the only one who keeps saying OLTP instead of OTLP? 🙄 #OpenTelemetry

Tracing slow Drupal requests gets more practical with OpenTelemetry and Valkey. The article shows how distributed traces can expose where latency builds up across application, cache and service layers.
