As any web application, verdaccio has a customisable built-in logger. You can define multiple types of outputs.

```yaml
logs:
  # console output
  - {type: stdout, format: pretty, level: http}
  # file output
  - {type: file, path: verdaccio.log, level: info}
```

Use `SIGUSR2` to notify the application, the log-file was rotated and it needs to reopen it.

### Configuration

Property | Type | Required | Example | Support | Description
--- | --- | --- | --- | --- | ---

path | string | No | verdaccio.log | all | if type is file, define the location of that file
format | string | No | [pretty, pretty-timestamped] | all | output format
level | string | No | [fatal, error, warn, http, info, debug, trace] | all | verbose level
