# fluent-plugin-map

fluent-plugin-map(out\_map) is the non-buffered plugin that can convert an event log to different event log(s)

## Example

This sample config output code file and time file.

    <source>
      type tail
      format apache
      path /var/log/httpd-access.log
      tag tag
    </source>
    <match tag>
      type map
      map [["code." + tag, time, {"code" => record["code"].to_i}], ["time." + tag, time, {"time" => record["time"].to_i}]]
      multi true
    </match>
    <match code.tag>
      type file
      path code.log
    </match>
    <match time.tag>
      type file
      path time.log
    </match>


The parameter "map" can use 3 variables in event log; tag, time, record. The format of time is an integer number of seconds since the Epoch. The format of record is hash.
The config file parses # as the begin of comment. So the "map" value cannot use #{tag} operation.
This plugin can output multi logs by seting multi to true.

If you don't use multi option, you can use key, time, record parameter. The 2 following match directive is same:

    <match tag>
      type map
      map ["code." + tag, time, {"code" => record["code"].to_i}]
    </match>
    <match tag>
      type map
      tag "code." + tag
      time time
      record {"code" => record["code"].to_i}
    </match>
