Airbnb's metrics migration¶

Another great end-user story, this time around via the Airbnb Tech Blog: Eugene Ma's Building a high-volume metrics pipeline with OpenTelemetry and vmagent.

apt install opentelemetry¶

An excellent proposal put forward by an excellent person: read Project Proposal: system packages, by Michele Mancioppi, via the OTel community repo.

Prometheus all the things¶

My colleagues Nilo Bustani, Rodrigue Koffi, and Alexis Perez-Mendoza wrote Simplifying Prometheus metrics collection across your AWS infrastructure.

OpenTelemetry talks@KubeCon¶

If you, like me, missed KubeCon, here two handy updates: 1. the Observability Day Europe 2026 video recordings are now available online, and 2. the one and only Juraci Paixão Kröhling provides guidance with Six OpenTelemetry talks worth watching from KubeCon EU 2026.

OpenSearch goes GenAI¶

Check out Open-source AI Agent Evaluation & Observability, an OpenSearch project that helps you evaluate, monitor, and optimize AI agents.

Who watches the watchers?¶

Elizabeth of SigNoz shared Our Project Hail Mary: The Observability Setup Behind an Observability Tool, reporting on their internal observability system.
