Component

ParserOutput

Parse string in log message, and re-emit.

DeparserOutput

Generate string log value from log message, with specified format and fields, and re-emit.

Configuration

ParserOutput

ParserOutput has just same with 'in_tail' about 'format' and 'time_format':

<match raw.apache.common.*>
  type parser
  remove_prefix raw
  format /^(?<host>[^ ]*) [^ ]* (?<user>[^ ]*) \[(?<time>[^\]]*)\] "(?<method>\S+)(?: +(?<path>[^ ]*) +\S*)?" (?<code>[^ ]*) (?<size>[^ ]*)$/
  time_format %d/%b/%Y:%H:%M:%S %z
  key_name message
</match>

Of course, you can use predefined format 'apache' and 'syslog':

<match raw.apache.combined.*>
  type parser
  remove_prefix raw
  format apache
  key_name message
</match>

If you want original attribute-data pair in re-emitted message, specify 'reserve_data':

<match raw.apache.*>
  type parser
  tag apache
  format apache
  key_name message
  reserve_data yes
</match>

DeparserOutput

To build CSV from field 'store','item','num', as field 'csv', without raw data:

<match in.marketlog.**>
  type deparser
  remove_prefix in
  format %s,%s,%s
  format_key_names store,item,num
  key_name csv
</match>

To build same CSV, as additional field 'csv', with reserved raw fields:

<match in.marketlog>
  type deparser
  tag marketlog
  format %s,%s,%s
  format_key_names store,item,num
  key_name csv
  reserve_data yes
</match>
