Even years after the initial impact, the demand continues to grow steadily. In this context, traffic monitoring and analysis are essential to effectively meet this demand and improve the services offered by internet service providers. Evaluating the effectiveness of the tools used for traffic monitoring and analysis in a dynamic internet service provider scenario contributes to the enhancement of network management, resulting in more reliable and efficient services. This study aims to implement and assess the practical effectiveness of open-source tools for traffic monitoring and analysis in an ISP scenario. Initially, traffic monitoring and analysis were conducted using the NetFlow flow export protocol, followed by the implementation and practical evaluation of the open-source tools flow-tools and FlowViewer. During the implementation of the toolset on the server, challenges related to code errors in the software scripts arose, requiring additional effort to identify and correct the errors. This required a certain level of knowledge in Shell Script and Perl, as well as time for adjustments. Overcoming these difficulties demonstrated the technical feasibility of the tools; the user-friendly and easy-to-use interface of FlowViewer made it easier to obtain and interpret the data captured by flow-tools. The detailed traffic analysis, based on data provided by FlowViewer’s reports, allowed for the identification of traffic patterns, focusing on traffic volume, transmission rates, and the most frequently used network ports. This experience highlights the feasibility of adopting these tools in ISP environments, proving that it is possible to effectively monitor and analyze complex network traffic using free solutions.Acesso AbertoTráfego de redesExportação de fluxosOpen-sourceNetwork trafficFlow exportCNPQ::CIENCIAS EXATAS E DA TERRA::CIENCIA DA COMPUTACAO::SISTEMAS DE COMPUTACAO::TELEINFORMATICATrabalho de Curso - Graduação - MonografiaAttribution-NonCommercial-NoDerivs 3.0 Brazil
