Pipeline does'n work

Graylog Central (peer support)

Hello!

  1. I use Graylog v3.3.9+abab7dc
  2. I created GELF-HTTP Input.
  3. I added stream for this input.
  4. I created pipeline for new stream.
  5. I added simple rule
    rule “Add date fields”
    when
    true
    then
    set_field(“let_1”, “1”);
    end
  6. There is no new field (“let_1”) in new stream’s messages.
  7. “Pipeline Processor” is enabled.

Could you help me?

Plese be more verbose, especialy how did you configure stream connection for pipeline:

Check also you processing order, Message Filter Chain and Pipeline Processor

You are right. Processing order is important.
Thanks.
