☕ Café com Gomex

Nesse quadro eu quero falar rapidinho sobre temas que fazem parte do nosso dia a dia.

No episódio de hoje eu falo sobre troubleshooting. Quando um problema aparece em produção, eu gosto de pensar como uma emergência: tem algo em risco e precisa de resposta rápida e organizada.

Para investigar bem um problema, três coisas fazem muita diferença:

🔎 Log centralizado com labels corretas, para conseguir buscar informação sem se perder em um mar de logs.

📊 Métricas mais precisas, em vez de sair metrificando tudo e gerar mais ruído do que sinal.

🧵 Tracing, que permite acompanhar o caminho da requisição e entender exatamente onde está o problema. E às vezes nem é código — pode ser rede, banco ou conexão.

☕ Agora me conta aqui: que tema você quer ver no próximo Café com Gomex?
Também pode mandar dúvidas. Pode virar vídeo.

I wrote a blurb about "Distributed Tracing with OBI“ https://www.pilhuhn.de/docs/2026/tracing_obi/. It is kind of a work in progress, but complete enough to get started with OpenTelemetry-OBI.

[Draft] Distributed tracing with OBI

This article describes how to get trace signals for code, that we can not modify.

#MotherJones #reporter has done a complex job in #tracing what appear to be deliberate #attempts by #BillPulte to #disguise cash #gifts or #payments related to #Trump #lawsuit as #charitable #donations. #Pulte now runs the #Federal #Housing #Finance #Agency.

What was Bill Pulte’s charity really funding with this mystery donation?

It gave $65,000 to a nonprofit that records suggest is an LLC linked to Trump's legal defense.

에이전트 대화에서 생성된 코드로 연결해 추적하는 오픈 표준을 제안한다는 발표입니다. 이 표준은 특정 코딩 에이전트나 인터페이스에 구애받지 않고 상호운용 가능하도록 설계되어, 에이전트 기반 코드 생성의 추적성, 감사성, 디버깅 워크플로우 개선에 기여할 수 있습니다.

We're proposing an open standard for tracing agent conversations to the code they generate. It's interoperable with any coding agent or interface. https://t.co/jO4DIoIl6A

OTelBench: AI struggles with simple SRE tasks (Opus 4.5 scores only 29%)

Benchmarking OpenTelemetry: Can AI trace your failed login? - Quesma Blog

A lot of vendors pitch AI SRE. We tested 14 models across 11 programming languages; even the best ones struggle with instrumenting code with the leading open-source standard, OpenTelemetry.

My version of #lofigirl based on @jooleah Traced a lot from the original. I took pictures of the accessories like the MPC, banker's lamp, and nickelodeon alarm clock. then digitally traced over them on a tablet using photoshop. No AI or generator type stuff, lots of layers.

Vercel ra mắt AI Gateway ở giai đoạn GA, khẳng định chỉ fetch LLM không đủ cho môi trường sản xuất. Hệ thống gồm 3 giai đoạn: **Gateway** – shim chuyển đổi schema giữa OpenAI, Anthropic, Gemini; **Tracing** – dùng OpenTelemetry + exporter tùy chỉnh để ghi lại các span đa cấp, giúp debug luồng agent; **Evals** – đánh giá chất lượng từng bước qua trace. Giải pháp giảm vendor lock‑in, tăng độ tin cậy và khả năng kiểm soát. #Vercel #AI #Gateway #OpenTelemetry #OTel #Tracing #Observability #CôngNghệ

I'm happy my talk "Combining Trace(r)s: Kernel ftrace & LTTng UST" was accepted in the #kernel devroom at #fosdem . Looking forward to meet you there!
