Target field in ndjson

[ddoroshenko (Dmitriy)]

Hi!

I have a log file with json records like

{
  "request": {
    "foo": "bar"
  },
  "response": {
    "foo": "bar"
  }
}

and the following configuration for filebeat

- type: filestream
  paths:
    - /path/to/file
  tags: ["tags"]
  fields_under_root: true
  fields:
    field1: value1
  parsers:
    - ndjson:
        target: root
        overwrite_keys: true
        expand_keys: true

So I want to see the parsed fields like root.request.foo and root.response.foo but it doesn't works.

With target: "" it normally parse log records to request.foo and response.foo

Whats could be wrong?

Hi @ddoroshenko

did you try to add add_error_key: true configuration and check if you can see any errors?
do you actually have root field? what will happen if you change the target field to not yet existing one?

I'm very sorry
It was simpy inattention. I had target at the wrong level
