The article by Nicolás Bevacqua explores the journey of integrating and utilizing the Elastic Stack, formerly known as the ELK Stack, comprising Elasticsearch, Logstash, and Kibana, for better data visualization and server metrics analysis. The author explains how this powerful trio can provide insights into platform operations by setting up Elasticsearch for indexing, Logstash for data streaming from various sources, and Kibana for visualizing the collected data. The narrative details the step-by-step process of upgrading to Elastic Stack 5.x, configuring services, and integrating Node.js and nginx logs into the system. The article highlights the practical applications of Logstash in processing diverse data inputs and outputs, as well as the use of Kibana to create visualizations such as pie charts, line charts, and geographic maps to understand application performance and traffic patterns. Additionally, the author discusses the importance of automation and security using X-Pack to enhance the Elastic Stack's functionality, ultimately offering comprehensive insights into server performance through a centralized dashboard.
