Description
editThis codec will decode streamed JSON that is newline delimited.
Encoding will emit a single JSON string ending in a @delimiter
NOTE: Do not use this codec if your source input is line-oriented JSON, for
example, redis or file inputs. Rather, use the json codec.
More info: This codec is expecting to receive a stream (string) of newline
terminated lines. The file input will produce a line string without a newline.
Therefore this codec cannot work with line oriented inputs.

Default value is
"UTF-8"
The character encoding used in this codec. Examples include UTF-8 and
CP1252
JSON requires valid UTF-8 strings, but in some cases, software that
emits JSON does so in another encoding (nxlog, for example). In
weird cases like this, you can set the charset setting to the
actual encoding of the text and logstash will convert it for you.
For nxlog users, you’ll want to set this to CP1252

target
edit- Value type is string
- There is no default value for this setting.
Define the target field for placing the parsed data. If this setting is not set, the JSON data will be stored at the root (top level) of the event.
For example, if you want data to be put under the document field:
input {
http {
codec => json_lines {
target => "[document]"
}
}
}
