Kibana
Kibana is an open-source data visualization and exploration tool designed for analyzing and visualizing data stored in Elasticsearch. It provides a web-based interface with features like dashboards, charts, graphs, and maps to help users monitor, search, and interact with their data in real-time. It is a core component of the Elastic Stack (formerly ELK Stack), alongside Elasticsearch, Logstash, and Beats.
Developers should learn Kibana when working with large-scale log, metric, or event data that requires real-time monitoring, troubleshooting, and business intelligence. It is essential for use cases such as application performance monitoring (APM), security analytics (SIEM), and operational dashboards in DevOps or IT environments. Kibana simplifies data exploration and visualization, making it easier to derive insights from complex datasets without deep coding expertise.
