This exporter is being deprecated in favour of the [debug exporter]. It will be removed in September 2024.

Exports data to the console via zap.Logger.

Supported pipeline types: traces, metrics, logs

## Getting Started

The following settings are optional:

- `loglevel` (default = `info`): the log level of the logging export
  (debug|info|warn|error). When set to `debug`, pipeline data is verbosely 
  logged.
  - **Note**: This option has been deprecated in favor of `verbosity`
- `verbosity` (default = `normal`): the verbosity of the logging export
  (detailed|normal|basic). When set to `detailed`, pipeline data is verbosely
  logged.
- `sampling_initial` (default = `2`): number of messages initially logged each
  second.
- `sampling_thereafter` (default = `500`): sampling rate after the initial
  messages are logged (every Mth message is logged). Refer to [Zap
  docs](https://godoc.org/go.uber.org/zap/zapcore#NewSampler) for more details
  on how sampling parameters impact number of messages.

### Note
`loglevel` is deprecated, use `verbosity` instead.

Example:

```yaml
exporters:
  logging:
    verbosity: detailed
    sampling_initial: 5
    sampling_thereafter: 200
```
