# Observability

See what your services are doing: stream logs, track metrics and cost, and review deploy and replica history.

## In this section

- [Logs](https://lizard.build/docs/observability/logs) — live and historical logs, including build and restart logs.
- [Metrics & Cost](https://lizard.build/docs/observability/metrics) — resource usage and what it costs.
- [Events & History](https://lizard.build/docs/observability/events) — deploy timeline and per-replica status.

Every view here also has a `--json` form, which is what an AI coding agent reads when a deploy misbehaves — see [deploying from Claude Code](https://lizard.build/blog/deploy-from-claude-code).
