ELK Stack

Elasticsearch, Logstash, and Kibana — the most popular open-source log management platform.

The ELK Stack (Elasticsearch, Logstash, Kibana) is the world's most popular open-source log management and analytics platform. Elasticsearch is a distributed, RESTful search and analytics engine that indexes and stores data for lightning-fast search, while Logstash is a server-side data processing pipeline that ingests data from multiple sources, transforms it, and sends it to Elasticsearch. Kibana provides the visualization layer, enabling users to create dashboards, explore data, and set up alerts. Together, they form a complete pipeline for collecting, searching, analyzing, and visualizing log data at petabyte scale. The stack has grown to include Beats for lightweight data shippers that send data from edge machines, and supports security features like authentication, encryption, and role-based access control in the Elastic Stack ecosystem.
