Lightning talks day1
summary
Systems expose a single /health endpoint that performs many checks and returns 200 or 500 with timing and error details; it’s polled by monitoring, used after deploys and during setup, and helps trace cascading failures. The team packaged the repeated pattern as the open source gem minicheck (Rack middleware), with Elixir ports available, but warns that health checks can create an infinite loop between services and leak stack traces so hide them behind auth or a proxy.
