# Log formats

Dagger exposes 2 logging format options:

- `--log-format auto|plain|tty|json`

The default mode is `auto`. If you want to keep each actions' logs, use the `plain` mode

- `--log-level panic|fatal|error|warn|info|debug|trace`

`debug` is useful to check whether an explicit dependency has been found between two actions.

You can also export these options as env variables:

```console
export DAGGER_LOG_FORMAT="plain"
export DAGGER_LOG_LEVEL="debug"
```
