A Symfony app in production always looks fine… until it doesn’t. Latency spikes. CPU climbs. Memory behaves weirdly. Nobody knows why.

Take a Symfony application behind FrankenPHP and make it observable in minutes. No heavy stack. No endless setup. Just the signals that actually matter to us as developers.

We tap into what the runtime and the server already expose, then turn that into something useful when debugging real production issues.

We end up with a simple, working observability setup: request visibility, latency tracking, resource usage, and runtime signals you can actually rely on in production.

The goal is simple: understand what your app is really doing in production without spending days wiring tools together. Make observability enjoyable.
