You run Kestrel as a message queue and now want to send the messages into various other systems. One way to achieve this is by sending messages through Fluentd.

The benefit of this approach is:

  1. No need to gut out the existing Kestrel instances.
  2. Take advantage of Fluentd's rich set of output plugins. For example, sending data from Kestrel to both HDFS and Amazon S3.


  1. Install the Kestrel input plugin by running the following command

    $ fluent-gem install fluent-plugin-kestrel
  2. Open your Fluentd configuration file and add the following lines:

      type kestrel
      host localhost     # (required) kestrel host
      queue fluent       # (required) kestrel queue name
      tag kestrel.log    # (required) fluentd tag
      port 22133         # (optional) kestrel port. default 22133
      timeout 10         # (optional) default 10.
