Introduction
Elasticsearch
Elasticsearch is a search engine and NoSQL database. It’s designed for storing, retrieving, and managing semi-structured data. In the context of ELK, it’s used for storing log data in a scalable, distributed manner, making it possible to perform complex search and analysis on large volumes of data.
Logstash
Logstash is a log processing tool that can be used to collect, process and store logs. It can be used to extract data from various sources, transform the data, and send it to a target like Elasticsearch. Logstash is used to collect log data from various sources, transform it, and send it to Elasticsearch for indexing and analysis.
Kibana
Kibana is a data visualization tool that provides a web-based interface for searching, exploring, and visualizing data stored in Elasticsearch. It provides an easy-to-use interface for analyzing log data, creating visualizations and dashboards, and detecting patterns and trends. Kibana is used to interact with the log data stored in Elasticsearch and provide insights into the data through visualizations and dashboards.
