Elasticsearch is today's de-facto standard for centralized logging and real-time analytics for system metrics and business data. What started as a full-text search engine quickly became much, much more than just that.
This intensive 2-day hands-on workshop is designed to teach you the Elastic Stack from the ground up. You will start by learning the basics of full-text search and information retrieval and the important Elasticsearch APIs: Document, Indexes, Queries and Aggregations APIs.
Only once you are fluent with the Elasticsearch APIs you can really use the powerful Elastic Stack to its full potential. Formerly known as ELK, the Elastic Stack has several components (Elasticsearch, Logstash, Kibana, Beats, and several Stack-wide solutions), and you will learn how to make good use of them all.
The goal of this course is to provide an experienced developer with all the tools to succeed with integrating Elasticsearch into any type of project. You will learn:
- Using Elasticsearch to add full-text search to any application.
- Define and maintain Elasticsearch indexes, and correct data ingestion using Logstash and Beats.
- Perform aggregation queries to drill-down into your data.,
- Use Kibana to investigate live data and create visually appealing dashboards.,
- Working with time-series data (logs, IoT, and more).
- Understand where the Elastic Stack shines and how to use it correctly.
Developers, DevOps and SREs with 3 years of experience or more. Platform agnostic - hands-on exercises are using Kibana end-to-end.
