Opensearch-filebeat-processors

Hi
I am using filebeat to push the logs directly into Opensearch.
There is a need to massage the data before ingesting to opesearch for analytical purpose.
So i am trying with dissect processor on the field ‘message’ and the result is as expected.
My Config is

processors:

  • add_host_metadata: ~
  • add_cloud_metadata: ~
  • dissect:
    when:
    contains:
    message: “Status”
    tokenizer: “%{loglevel} [%{comp}] %{mkt} status=%{status}”
    field: “message”
    target_prefix: “”

When i do the dissect, will the original message will be lost/hampered.
Is it good to copy the message into another field and then do the massaging.

Appreciate inputs on this.

Thanks
H
