Pipeline does'n work

[Sergei]

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.
