‼️ #OpenTelemetry is deprecating the Span Events API. Our aim is to remove the confusion caused by having overlapping ways to emit events: span events and log-based events. Read our latest post to learn more about how you can prepare. buff.ly/0hOwfuk
Deprecating Span Events API
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…

I just published a blog post on an experiment I did with building a dry-run mode for the OpenTelemetry Collector. It's a work in progress, and was mainly built to scratch my own itch, but nonetheless -- enjoy! ubuntu.com/blog/buildin... #observability #otel #o11y #sre
Building a dry-run mode for the OpenTelemetry Collector | Ubuntu
Teams continuously deploy programmable telemetry pipelines to production, without having access to a dry-run mode. At the same time, most organizations lack staging environments that resemble producti...

CloudWatch charges you $0.50/GB to ingest logs, $0.03/GB/month to store them, and $0.005/GB every time you search them. During an incident, your query volume spikes and so does your bill.
At OTel Unplugged EU, OpenTelemetry's maintainers laid out an ambitious roadmap — from smarter sampling and entity definitions to Arrow's stateful OTLP.

Maybe I’m just mad because I missed the easiest grift in history: take existing o11y vocabulary, swap “request_id” for “prompt_id”, ship a dashboard, print money
We cut @nodejs memory in half with a one-line Docker image swap. No code changes. No new APIs. Just smaller heaps. Here's what happened when we tested pointer compression on real workloads 🧵
Been having a lot of fun pushing evlog lately: zero‑dependency core, wide events, structured errors, and fresh adapters for PostHog, Sentry, OTLP, Axiom & Workers. Into observability with good DX? This might be your new favorite logging layer → dub.sh/better-log
evlog - Logging that makes sense
Wide events and structured errors for TypeScript. One log per request, full context, errors that explain why and how to fix.

The OTLP HTTP exporter is the boundary against data loss. To build a resilient #observability pipeline, you need to tune persistence and backoff. We explain how to configure #OpenTelemetry so a simple network blip doesn’t turn into an #SRE incident. Full deep dive 👉 dash0.link/otel-otlp-ht...

Hey OpenTelemetry experts, anyone know of any drop-in replacement of Sentry SDKs (for error tracking) that record exceptions in OTel span events? Mostly for backend error tracking. Sentry compatible SDK/API is enough to migrate away from Sentry, not looking for a complete error tracking product.

Sentence that fell out of my mouth with 100% seriousness today: "Ooooh! I'm gonna do OpenTelemetry to your soldering iron." Realizing several hours after the fact that I could have phrased this better, or at least a bit less like a threat. 🤷
Atuin Desktop just got a brand new runtime! Runbooks are now - reproducible (context flows down, no global state) - persistent (state survives restarts) - executable anywhere (CI, remote machines, anything) This is the first step towards making runbooks an actual automation primitive
Introducing the New Runbook Execution Engine
We're excited to announce a major architectural improvement to Atuin Desktop: a completely redesigned runbook execution engine.
