Sending logs to multiple outputs simultaneously

[akhamis-tc]

Hi everyone,

I'm trying to send logs to different outputs simultaneously based on key attribute values. Below is roughly the configuration I'm trying to achieve.

<source>
  @type forward
  port 24224
  bind 0.0.0.0
</source>

 <filter **>
  @type record_transformer
  <record>
    tag $${tag}
    backend1 true
    backend2 true
    backend3 false
  </record>
</filter>

So given the current configuration, logs should be sent to backend1 and backend2 simultaneously, but not backend3. What is the best way to approach this?

Another option could be to use a tag/label/attribute backend and use values like backend1, backend2, ... In such a case the question is how to send it to multiple backends. Can we use the same tag twice (backend backend1, backend backend2) or do we have to send a list or an array (backend backend1,backend2).
