The Four Categories a Production System Must Log

Monitor system performance using logging and observability tools

SUBy Solomon UdohReviewed by Solomon UdohAI-assisted · human-reviewed
In short
A production Claude system should log four categories: the request (model version, input token count, prompt identifier), the response (output token count, latency, stop reason), the context (user role, session ID, whether caching applied), and the outcome (whether the downstream system accepted the output). An unlogged data path is invisible when something goes wrong on it, and observability built after the first incident cannot answer questions the log data was never designed to capture. Security reviewers increasingly treat a trustworthy audit trail as a precondition for approving an autonomous agent to act.
