Syllabus

What Is Logging and Elasticsearch

Build a strong foundation in logging by exploring why logs matter in distributed systems and how Elasticsearch became a core engine for search and analytics. This module frames centralized logging as an operational necessity for troubleshooting, observability, and incident response.

Mastering Elasticsearch Fundamentals

Learn the core building blocks of Elasticsearch, from nodes, clusters, and indices to mappings, shards, and replicas. You will also practice CRUD operations and common API patterns so you can confidently ingest, query, and manage log data in Elasticsearch.

Understanding Kibana

Discover how Kibana helps you turn log data into actionable insight. In this module, you will search data with KQL, build dashboards and maps, and create interactive visualizations that make it easier to monitor systems and investigate issues.

Fluent Bit

Understand the log shipping layer of the EFK stack by focusing on Fluent Bit and its lightweight architecture. You will compare it with Logstash and Fluentd, learn where it fits in production pipelines, and explore how plugins move logs from source to destination.
