Using elasticsearch, logstash & kibana to create realtime dashboards

This talk was presented by Alexander Reelsen at the Lightweight Java User Group Munich.

The first part of the presentation covers an introduction into Logstash, followed by a deeper dive into its operations via creating a real-time dashboard using Kibana and the meetup.com reservation stream.
