tcp-reset-fgraph - TCP Reset Flame Graph

This analyzer profiles TCP connection reset events across all applications. It captures C-level stack traces when TCP RST packets are sent or received, tracking the code paths leading to connection termination. The analyzer generates flame graphs showing where TCP resets originate, helping troubleshoot connection stability issues and identify problematic network interactions.
