== Component

=== FilterOutput

Filtering messages by simple allow/deny rules.

== Installation

Add this line to your application's Gemfile:

    gem 'fluent-plugin-filter'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install fluent-plugin-filter

== Configuration

=== FilterOutput

Filter out messages contains <tt>{status : 404}</tt> :

    <match accesslog.**>
      type filter
      all allow
      deny status: 404
    </match>
    <match filtered.**>
      type stdout
    </match>

in above configuration, {status: 404} is filtered out and {status: 200}, {status: 303}, {status: 401} passed.
Messages passing filter are add_prefix (default filtered.)

So you catch "filtered" tag and do next process.
