title: Observe
description: Logs, traces and metrics for every service, kept inside ops.
order: 4
---

Everything your services tell ops stays inside ops: nothing is sent to an outside service.
Each project sees its own and nothing else.

- [Logs](logs.md): what your containers print, searchable and followed live.
- [Traces](traces.md): requests as trees of spans.
- [Metrics](metrics.md): request rates, memory and the numbers your services expose.

| --- | --- |
| logs | 14 days, unless your project was given another window (30 at most) |
| traces | 7 days |
| metrics | 3 days at full detail, 13 months as five minute averages |
