We are streaming app logs from CloudWatch to AWS ELK. Our microservices are written in Java and so I am only concentrating on those. A typical java exception stack trace when logged looks like this: Exception in thread "main" java.lang.NullPointerException at com.example.myproject.Book.getTitle(Book.java:16) at com.example.myproject.Author.getBookTitles(Author.java:25) at com.example.myproject.Bootstrap.main(Bootstrap.java:14) Normally, this will be ingested line by line in ELK stack, which breaks the entire message. Usually, For entire stack trace to be ingested as a single message, one can configure multiline plugin either in Logstash or Filebeat. Any idea how to enable multiline while streaming log files from CloudWatch to ELK by AWS lambda? ---
