What is the Elastic / ELK Stack?

    The Elastic Stack is a set of open-source tools developed by Elastic that are used for logging, searching, and analyzing large datasets. The stack consists of four main components:

    1. Elasticsearch – A distributed search and analytics engine that provides full-text search, real-time analytics, and structured search capabilities.
    2. Logstash – A data processing pipeline that helps to collect, parse, and transform logs and other event data from various sources.
    3. Kibana – A data visualization and dashboarding tool that helps to visualize and analyze data stored in Elasticsearch.
    4. Beats – A family of lightweight data shippers that can be used to send data from various sources such as logs, metrics, and network packets to Elasticsearch and Logstash.

    The Elastic Stack is widely used by organizations to monitor and analyze their infrastructure and application logs, security logs, and other data sources. It provides a powerful set of tools that allow users to quickly and easily collect, analyze, and visualize large datasets, enabling organizations to make informed decisions based on their data.
