Output Filter for renaming fields

adnanrahic commented 4 years ago

This PR adds an output filter for renaming fields in log lines.

Eg.

outputFilter:
  rename-fields:
    module: rename-fields
    # JS regular expression to match log source name
    matchSource: !!js/regexp .*
    fields:
      - fieldName: user
        renameTo: user_object

This will rename the the user field into user_object.

Example:

Input

{"user": "{ name: root }", "message": "Client connect: root", "originalLine": "INFO Client connect: root"}

Output

{"user_object": "{ name: root }", "message": "Client connect: root", "originalLine": "INFO Client connect: root"}
