=== Json codec plugin

include::{include_path}/plugin_header.asciidoc[]

==== Description

This codec may be used to decode (via inputs) and encode (via outputs)
full JSON messages. If the data being sent is a JSON array at its root multiple events will be created (one per element).

If you are streaming JSON messages delimited
by '\n' then see the `json_lines` codec.

Encoding will result in a compact JSON representation (no line terminators or indentation)

If this codec recieves a payload from an input that is not valid JSON, then
it will fall back to plain text and add a tag `_jsonparsefailure`. Upon a JSON
failure, the payload will be stored in the `message` field.

  * 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 may to set this to "CP1252".
