# Zipkin

In addition to the built-in `runtime.task_history` SQL table, Spice can export the observability traces it collects into Zipkin.

### Enabling Zipkin Export

Zipkin export is defined in the `spicepod.yaml` under the `runtime.tracing` section:

```yaml
runtime:
  tracing:
    zipkin_enabled: true
    zipkin_endpoint: http://localhost:9411/api/v2/spans
```

* `zipkin_enabled`: Optional. Default `false`. Enables or disables the Zipkin trace export.
* `zipkin_endpoint`: Required if `zipkin_enabled` is true. The path to the `/api/v2/spans` endpoint on the Zipkin instance to export to.
