<p>This codec handles fluentd’s msgpack schema.</p>
<p>For example, you can receive logs from <code class="literal">fluent-logger-ruby</code> with:</p>
<div class="pre_wrapper lang-ruby">
<pre class="programlisting prettyprint lang-ruby"> input {
tcp {
codec => fluent
port => 4000
}
}</pre>
</div>
<p>And from your ruby code in your own application:</p>
<div class="pre_wrapper lang-ruby">
<pre class="programlisting prettyprint lang-ruby"> logger = Fluent::Logger::FluentLogger.new(nil, :host => "example.log", :port => 4000)
logger.post("some_tag", { "your" => "data", "here" => "yay!" })</pre>
</div>
<p>Notes:</p>
<div class="ulist itemizedlist">
<ul class="itemizedlist">
<li class="listitem">
the fluent uses a second-precision time for events, so you will never see
subsecond precision on events processed by this codec.
</li>
</ul>

<p>Add a unique <code class="literal">ID</code> to the plugin configuration. If no ID is specified, Logstash will generate one.
It is strongly recommended to set this ID in your configuration. This is particularly useful
when you have two or more plugins of the same type, for example, if you have 2 grok filters.
Adding a named ID in this case will help in monitoring Logstash when using the monitoring APIs.</p>
