An artist files a ticket: "Blender crashed while I was sculpting." No .blend, no repro steps, no idea which add-ons were running. You try to reproduce it, fail, and close it cannot reproduce. Every team that supports a DCC tool knows this loop.
The full Micromegas stack — ingestion, analytics, maintenance, web UI — now fits in a free-tier VM. One binary, one Postgres, one object store. That's it.
This is the micromegas-monolith: a single process that runs all four roles on one tokio runtime, sharing a data-lake connection, a cache, and a SIGTERM fanout. Spin it up on a free-tier VM, your laptop, or whatever throwaway instance your cloud provider gives away. Point your instrumented app at it. Get logs, metrics, and traces with a full SQL query interface and a web UI, for essentially zero running cost.
That's the pitch for personal telemetry. For teams it's also the fastest demo path: one compose file, no orchestration.
Micromegas's native instrumentation — a Rust crate and an Unreal Engine plugin — gives you about 20ns per event and 100k events per second per process. It's the cheapest way to get telemetry out of code you control. The hard part is "code you control" — production systems are full of code you can't recompile.
You don't need a complex system to interrogate your infrastructure.
Weekend project: I wanted to document how to instrument a Bevy game with telemetry, so I ended up writing one.
Apache DataFusion already supports compiling to WebAssembly — so we took advantage of it. Full SQL running client-side, the same query engine that powers the Micromegas backend, now running in a browser tab. And it scales your analytics compute for free.
The games industry is cutting thousands of jobs. But is it cutting the right things?
Just presented our unified observability approach for Unreal Engine games. The debugging loop we all know — and how to break out of it.
I had the chance to present Micromegas at OSAcon 2025.
Excited to share the latest release of Micromegas, our open-source high-frequency observability platform for logs, metrics, and traces.
