Write

The event-write processor writes a message that has a value or a tag matching one of the configured regular expressions to stdout, stderr or to a file. A custom separator (used between written messages) can be configured, it defaults to \n

processors:
  # processor name
  write-processor:
    # processor type
    event-write:
      # jq expression, if evaluated to true, the message is written to dst
      condition: 
      # list of regular expressions to be matched against the tags names, if matched, the message is written to dst
      tag-names:
      # list of regular expressions to be matched against the tags values, if matched, the message is written to dst
      tags:
      # list of regular expressions to be matched against the values names, if matched, the message is written to dst
      value-names:
      # list of regular expressions to be matched against the values, if matched, the message is written to dst
      values:
      # path to the destination file
      dst:
      # separator to be written between messages
      separator: 
      # indent to use when marshaling the event message to json
      indent:
