Automated code instrumentation for structured events
Hey HN! Sam, Alex and Ben from Invaria (formerly Patchwork Technologies): http://invaria.io. Observability is built on telemetry (metrics, logs and traces). Telemetry data quality is often poor because instrumenting code is still a time consuming task which requires a lot of hand-finishing. We believe that structured event data is the right end goal, and we’re starting by making it easier to get there using structured logging. For our Launch HN (Aug), we set up a demo instance with pre-baked results. We wanted to go further to allow HN readers to give the product a proper test…
Automated code instrumentation for structured events launched on October 16, 2024 with 21 votes, #833 of 5,185 launches that month and more than 75% of that year's launches.
In plain words
Invaria automates the instrumentation of code to generate structured event data for observability systems. The tool reduces the manual work typically required to create high-quality telemetry through structured logging, targeting developers who need better metrics, logs, and traces. It provides analysis of open-source repositories and allows users to enroll additional projects for automated instrumentation.

superlogJun 2026 · superlog.sh · ▲497Hey HN, we’re Nico and Arseniy, co-founders of Superlog (https://superlog.sh). We're building a self-installing, self healing observability tool meant not to be opened. It has a wizard that daily sets up proper logging and an agent that investigates errors and opens PRs. Super short demo: https://www.youtube.com/watch?v=xFhU9Mk247M. In our earlier startups, we tried Sentry, Datadog, Grafana, Dash0, and nothing was good enough. Proper telemetry and alerting still requires a ton of manual setup. We struggled with adding good logs, so debugging was tough, especially as…

OpenLLMetry – OpenTelemetry-based observability for LLMs2023 · github.com · ▲154Hey HN, Nir, Gal and Tomer here. We’re open-sourcing a set of extensions we’ve built on top of OpenTelemetry that provide visibility into LLM applications - whether it be prompts, vector DBs and more. Here’s the repo: https://github.com/traceloop/openllmetry. There’s already a decent number of tools for LLM observability, some open-source and some not. But what we found was missing for all of them is that they were closed-protocol by design, vendor-locking you to use their observability platform or their proprietary framework for running your LLMs. It’s still early in the…
You don't need to adopt new tools for LLM observability2024 · github.com · ▲102If you've built any web-based app in the last 15 years, you probably used something like Datadog, New Relic, Sentry, etc. to monitor and trace your app, right? Why should it be different when the app you're building happens to be using LLMs? So today we're open-sourcing OpenLLMetry-JS. It's an open protocol and SDK, based on OpenTelemetry, that provides traces and metrics for LLM JS/TS applications and can be connected to any of the 15+ tools that already support OpenTelemetry. Here's the repo: https://github.com/traceloop/openllmetry-js A few months ago we launched…

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
