The Elastic Stack
Elastic Search
Elasticsearch is a real-time, distributed storage, RESTful search, and analytics engine. It can be used for many purposes, but one context where it excels is indexing streams of semi-structured data, such as logs or decoded network packets.
Kibana
Kibana is an open source analytics and visualisation platform designed to work with Elasticsearch. You use Kibana to search, view, and interact with data stored in Elasticsearch indices. You can easily perform advanced data analysis and visualise your data in a variety of charts, tables, and maps.
