This document provides an introduction to exploring data using the Elastic stack, which includes Logstash, Beats, Elasticsearch, and Kibana. It outlines the basic steps to get data into Elasticsearch, explore it, clean and transform the data, and then productionize the data exploration process. A demo example is also presented that uses a cars.csv file to demonstrate exploring used car offerings data in the Elastic stack. The document concludes by noting how the general setup scales well for large data sets and recommends moving data transformation upstream and creating clean dashboards for end users.
