krump (rubygems): This application was written because of a need for a tail-like way to consume Kafka messages. kafka-console-consumer.sh, which is distributed with Kafka, allows you to either read all messages in a topic, or any new message. However, most often I want to to see the most recent few messages from a topic. Krump provides that as well as a number of other conveniences.
