Java multiline with add_docker_metadata

Elastic Stack Beats
1

We are using this:


and now we are trying to configure multiline to fetch Java stacktrace as a single message but any attempt fails.
We are pretty sure that patterns used to identify multiline are OK.
Is it possible to use multiline with Docker json logs?

Can you share your filebeat config?

Actually, I'm getting some kind of aggregation but also a lot of single lines, I don't understand the reason

filebeat.modules:
- module: kafka

filebeat.prospectors:
- type: log
  paths:
    - '/var/lib/docker/containers/*/*.log'
  json.message_key: log
  json.keys_under_root: true
  multiline.pattern: '^MSG|WNG|ERR'
  multiline.negate: true
  multiline.match: after
  tail_files: true
  processors:
  - add_docker_metadata: ~


setup.kibana:
  host: "plogelk06.mydomain.com:5601"

output.kafka:
  hosts: ["plogelk01:9092", "plogelk02:9092", "plogelk03:9092"]
  codec.format:
    string: 'beat=%{[beat]} message=%{[log]}'
  topic: 'test_svil_filebeat'
  partition.round_robin:
    reachable_only: false
  required_acks: 1
  compression: gzip
  max_message_bytes: 1000000

I can send you also some log lines but better privately as it is not easy to "anonymize".

Thanks

Yes please, send me those logs as a private message

Please accept my apologies: I had TWO filebeat containers running at same moment, with different configs!
