Sistema de monitoramento de arquivos de log de aplicação baseado na plataforma Elastic Stack

Abstract

Due to the constant popularization of the access to the Internet and computer systems, many companies and institutions are taking advantage of that context to implement the digitalization of their services to achieve better efficiency and accessibility in their activities through many computer solutions. To keep these systems working properly it is essential to monitor the working of the involved applications. That task can be made by reading log files, they are text files automatically generated by the applications that contain information about their functioning like the users’ access to the system and execution errors warnings. Reading those files can be hard because of some factors like the big quantity of generated text and its language that can be difficult to comprehend by a human. To make this task easier, this work proposes the creation of a monitoring system that will read those files, organize their data and show them using dashboards that are pages with graphics, tables and other interactive visual elements which allow the user an easier and faster reading of the log information in real-time. This system is made with the applications from the Elastic Stack group, they are: Beats and Logstash (reading and manipulation of data), Elasticsearch (data storage) and Kibana (data visualization). All the tools used in this project are freeware and open source and they also allow an easy portability between different operational systems.
