I think you'll need to add some more information before anybody can help you. Is that an NGINX proxy log or something? We have integrations that help ingest various types of logs.

You will need to implement additional parsing either using Logstash or Elasticsearch ingest pipeline. Based on the event.original, it looks like you are receiving a log in syslog format. I would foresee that you will need to look at grok and json filter/processor.
