This 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 includeUTF-8 andCP1252

JSON requires validUTF-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 toCP1252

• Value type isstring
• Default value is 512 MB

Maximum number of bytes for a single line before stop processing.

• Value type isstring
• Default value is"\n"

Change the delimiter that separates lines

• Value type isstring

• Supported values are:

  • disabled: does not use ECS-compatible field names
  • v1,v8: Elastic Common Schema compliant behavior (warns whentarget isn’t set)

• Default value depends on which version of Logstash is running:

  • When Logstash provides apipeline.ecs_compatibility setting, its value is used as the default
  • Otherwise, the default value isdisabled

Controls this plugin’s compatibility with theElastic Common Schema (ECS).

• Value type isstring
• 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 thedocument field:

input {  http {    codec => json_lines {      target => "[document]"    }  }}
