JSON Parser

The JSON parser plugin is used to take in a string and extract the fields when they are originally formatted as a JSON object.

Parameters

fields: The keys in the JSON data, separated by commas. For example “session_id,request_type,response_ms”.

accept_batch: OPTIONAL. If requests received may contain a batch of JSON records. NOTE that a batch of json records is NOT the same as a JSON array containing records inside a JSON array. These are independent records followed one by another in the same payload.
This parameter does not require a value. If you pass the parameter, then it’s taken as ‘true’.

Syntax

PARSER json (
    fields '<strings separated by comma>'
    accept_batch
)

Example

To parse records like…

{
    "session_id": "79238746923874",
    "request_type" "GET",
    "response_ms", 0.23
}

You can use

PARSER json (
    fields 'session_id,request_type,response_ms'
)

If the payload can contain multiple JSON records:

PARSER json (
    fields 'session_id,request_type,response_ms'
    accept_batch
)
