Access original, un-decoded input message

Elastic Stack Logstash

Hello,

How can I access the original input message before it was decoded so that I can refer to it from filter or output?

The setup is as follows:

  1. I am reading JSON from rabbitmq; the default codec is json and it breaks the message into fields (which is what I want).
  2. I am doing some basic transformation such as date matching on the extracted
  3. On output, I would like to take the original, un-decoded JSON value and insert as one of output fields.

How do I access that original input?

Do not use a json codec, use a json filter instead.
