You use `logging` exporter, see <https://github.com/open-telemetry/opentelemetry-collector/blob/main/exporter/loggingexporter/README.md>
Note loglevel is deprecated (info, debug, etc), use verbosity instead, see <https://github.com/open-telemetry/opentelemetry-collector/blob/main/config/configtelemetry/configtelemetry.go#L15-L26>
eg,
```exporters:
  logging:
    verbosity: detailed
    sampling_initial: 5
    sampling_thereafter: 200```
