# none

The `none` parser plugin parses the line as-is with the single field. This format is to defer the parsing/structuring of the data.

This parser is often used in conjunction with [`single_value`](https://docs.fluentd.org/formatter/single_value) format in output plugin.

## Parameters

See [Parse Section Configurations](https://docs.fluentd.org/configuration/parse-section).

### `message_key`

| type   | default | version |
| ------ | ------- | ------- |
| string | message | 0.14.0  |

Specifies the field name to contain logs.

## Example

This incoming event:

```
Hello world. I am a line of log!
```

is parsed as:

```
time:
1362020400 (current time)

record:
{"message":"Hello world. I am a line of log!"}
```
