For our December workshop, we went through the functionalities and benefits of using the Elastic Stack (formerly the ELK Stack).
This free and open-source set of tools provides the ability to collect, store and visualise data from any source. It is particularly useful to synthesize big amounts of data into one comprehensible dashboard, allowing its users to quickly extract relevant information out of data. The Elastic Stack consists of four different components: a dashboard (Kibana), a database (ElasticSearch) and two data collectors (Logstash and Beats).
