Elastic Stack Workshop

Elastic Stack Workshop

One of the hottest and most widely used tools for log monitoring and analytics at the moment is the Elastic Stack:
• Elasticsearch doing the hard work of analyzing and searching large amounts of data.
• Logstash and Beats for collecting them.
• Kibana for powerful visualizations.

This workshop gives you an overview of the four technologies, how they are working together, and how they can solve your problems.
