Fluentd v0.14.15 has been released

Hi users!

We have released v0.14.15. Here are the changes (full ChangeLog is available here):

We say again, fluentd v0.14 is still development version. We need your feedback seriously! If you try to use v0.14, check your configuration and plugins carefully.

<worker N> directive

We introduced built-in multi-process feature since v0.14.12(See release announcement). New <worker N> directive enhances multi-process feature.

The limitation of multi-process was non-multi-process ready plugin can't be used together. For example, we can't use in_tail plugin with workers parameter. Following configuration raises an error at startup.

<system>
  workers 4
<system>
<source>
  @type forward
</source>
<source>
  @type tail
</source>

<worker N> directive resolves this problem. You can invoke any plugins in specific worker(N is worker index) and plugins under <worker N> acts as if they work on single process environment. We can mix multi-process ready and non-multi-process ready plugins in one instance. Working example with above configuration is like below:

<system>
  workers 4
<system>
# work on multi process environment. worker0 - worker3 invoke in_forward plugin
<source>
  @type forward
</source>
# work on only worker 0. worker1 - worker3 don't invoke in_tail plugin
<worker 0>
  <source>
    @type tail
  </source>
</worker>
# <worker 1>, <worker 2> or <worker 3> is also ok

Plugin: Add formatted_to_msgpack_binary? method to Output plugin API

We use formatted_to_msgpack_binary method to tell "This plugin uses msgpack for event serialization" to output core when you customize format method. This name is not rubyish, so we add formatted_to_msgpack_binary? method for better name. We recommend to use formatted_to_msgpack_binary? for new plugins.

Of course, formatted_to_msgpack_binary method is available for existing plugins.

Windows: Add several options to configure Fluentd windows service information

By default, Fluentd uses following settings for Windows service registration:

  • Service name: fluentdwinsvc
  • Display name: Fluentd Windows Service
  • Service description: Fluentd is an event collector system.

Since v0.14.15, you can configure these settings via command line options.

  • Service name: --winsvc-name NAME
  • Display name: --winsvc-display-name DISPLAY_NAME
  • Service description: --winsvc-desc DESC

Major bug fixes

  • in_http: Fix X-Forwarded-For header handling. Accpet multiple headers
  • windows: Quote the file path to the Ruby bin directory when starting fluentd as a windows service

Enjoy logging!
