The tool generates detailed reports with summary statistics, top talkers, protocol breakdowns, and a tabular view of individual flows, helping network administrators monitor traffic and identify anomalies. It features a clean, responsive interface with client-side processing for quick analysis and optional server-side handling for larger datasets.
