대기업들이 AI와 에이전트 시장에 진입하면서 관측 가능성(observability) 수요가 커지고 있다. 특히 유럽에서는 규제 때문에 AI 레지스트리와 에이전트 단위의 기록 관리가 필요해지는 흐름이 강조된다.

Part 3 of the StyloBot Release Series is up.

https://www.mostlylucid.net/blog/stylobot-release-reliability

This one is less about bots and more about the reality of long-running .NET based systems: everything that learns from traffic eventually accumulates.

Came from one of my periodic reliability reviews where StyloBot’s vector layer had drifted to 13GB on the .NET Large Object Heap due to the wrong abstraction (in-process HNSW behaving like an unbounded cache).

The interesting part wasn’t the fix. It was recognising that the architecture itself was wrong for the runtime pattern.

Covers:

how I periodically review long-running services

using dotnet-counters, dotMemory and dotTrace to find growth

why “just add a cap” is often the wrong answer

replacing unbounded ANN structures with bounded hot caches + compacted persistence

taking the vector layer from 13GB LOH to <6MB

The broader point applies to any system that “remembers”:

bot detection, fraud scoring, recommendations, anomaly detection, RAG pipelines, adaptive systems.

Fix the shape, not the symptom.

Agent demos love static diagrams. Production gives you a different graph.

This post shows how to expose a live LangChain4j topology from Quarkus with AgentMonitor, HtmlReportGenerator, and an SSE feed for recent runs.

Show HN: Turn E2E tests into observability signals

Faultsense는 HTML에 테스트용 assertion을 추가하여 실제 사용자 세션에서 기능별, 사용자별, 릴리스별로 문제를 감지하는 웹 애플리케이션 관측 도구입니다. 기존의 에러 추적이나 RUM이 놓치는 문제를 구조화된 신호로 제공하며, 다양한 웹 프레임워크와 호환됩니다. 설치가 간단하고 실시간으로 assertion 상태를 모니터링할 수 있어, 문제 발생 시 신속한 진단과 수정이 가능합니다. 현재 디자인 파트너를 모집 중이며, 실제 프로덕션 환경에서 검증된 사례를 바탕으로 개발자에게 직접 지원을 제공합니다.

Building observability from scratch is a journey we have taken three times over to get it right. 🚀

We evolved from Nagios on a single box to a unified stack across thousands of virtual machines and identified the migration patterns that kept things smooth. ⚡

Explore our evolution and find the documentation you need to scale your own observability stack. 👉 https://developer.upsun.com/posts/how-it-works/building-observability-from-scratch-three-times-over
