tcp_analytics_test_start
int tcp_analytics_test_start(TcpAnalyticsSession *session, CONN *conn, off_t file_size)
Mark test start - capture "before" metrics.
Definition afp_tcp_analytics.c:271
tcp_analytics_capture
int tcp_analytics_capture(CONN *conn, TcpMetrics *metrics)
Capture TCP metrics from connection socket via getsockopt().
Definition afp_tcp_analytics.c:72
tcp_analytics_session_end
int tcp_analytics_session_end(TcpAnalyticsSession *session, CONN *conn)
Mark session end - capture "final" metrics and print session summary.
Definition afp_tcp_analytics.c:755
tcp_analytics_session_start
int tcp_analytics_session_start(TcpAnalyticsSession *session, CONN *conn)
Mark session start - capture "initial" metrics for size sweep mode.
Definition afp_tcp_analytics.c:263
tcp_analytics_test_end
int tcp_analytics_test_end(TcpAnalyticsSession *session, CONN *conn)
Mark test end - capture "after" metrics and print per-test comparison.
