Author: [Your Name/Institution] Date: April 14, 2026 Abstract Network traffic analysis is essential for security monitoring, capacity planning, and troubleshooting. NetFlow, originally developed by Cisco, provides a standard for exporting IP flow information. While many NetFlow collectors are designed for Unix-like operating systems, Windows-based environments remain prevalent in enterprise networks. This paper presents a comprehensive study of NetFlow collectors specifically for the Windows platform. It covers the NetFlow protocol fundamentals, the architecture of a Windows-based collector, installation and configuration of popular open-source and commercial collectors (e.g., nTop, PRTG, Scrutinizer, and Elastiflow on WSL), performance considerations, and practical use cases. Experimental results demonstrate that a properly tuned Windows collector can handle moderate to high flow rates (up to 20,000 flows/sec) with acceptable resource consumption. The paper concludes with best practices and recommendations for deploying NetFlow collection in Windows-centric networks. # Save as Check-NetFlowCollector
