Honza Král's talk from Europython 2016:
Centralized logging (and the Elastic stack) is proving itself to be a very useful tool in managing a production infrastructure. When combined with other data sources (application logging, business data, …) it can provide even more insight.
This talk is an introduction into the area with some overview of the motivation, tools and techniques that can prove useful. We will show how the open source ELK (Elasticsearch Logstash and Kibana) stack can be used to implement this.
It is geared towards people familiar with the DevOps concept that are looking to improve their lives by introducing smarter tools.
