# log (log (registro))

Your app's diary: one line per event. When something breaks, the logs say what happened.

**Analogy:** A ship's logbook.

**Example:** For example, your agent runs `npx vercel logs` to read the server log lines from a failed request—without ever logging secrets or personal data.
