Log message encoding of \n for multiline output

[kbrisso (Kevin)]

Hello All-

In my messages, some of the log messages actually have \n in the log output itself along with other random characters like XML tags. Is there a way to encode \n in file beat before shipping to log stash so the grok process doesn't split this into multiple messages? I am able to parse this as mutiline and grok the input in log stash. But the issue is embedded \n in the log output.

I was looking at this setting in file beat:

  # Configure the file encoding for reading files with international characters
  # following the W3C recommendation for HTML5 (http://www.w3.org/TR/encoding).
  # Some sample encodings:
  #   plain, utf-8, utf-16be-bom, utf-16be, utf-16le, big5, gb18030, gbk,
  #    hz-gb-2312, euc-kr, euc-jp, iso-2022-jp, shift-jis, ...
  #encoding: plain
