The Road from 2.4.4. to 5.3.2 and how we fixed our memory leak by Markus Kuenstner

After upgrading to ES 2.4.4 we discovered a strange behaviour on our ES nodes concerning the JVM Heap Space. This short insight presents our findings on how to analyse memory leaks and what we from Operations and Development did to (hopefully) fix the leak.

Collecting and analysing network flow data with Elastic Stack, by Robert Cowart

Network Flows offer a rich source of data, detailing the communications between systems in today's ever expanding and increasingly complex digital infrastructures. As commercial solutions struggle to provide the features and scale necessary to provide the information that users desire, Elastic Stack provides the perfect foundation for such a solution. Rob will explain how to use Elasticsearch, Logstash and Kibana to help users extract valuable insights from their network flow data, as well as other data sources. He will finish with an introduction to Elastic’s Machine Learning technology including a demo!
