ROOT CAUSE ANALYSIS
Figure 1.2 Root cause, with the confidence stated and the evidence behind it. Here the verdict is loss and retransmission at 50%, flagged preliminary rather than overstated.
RTT OVER TIME
Figure 1.3 RTT per direction across the flow, with queue and throughput overlays. Each layer toggles independently, and hovering syncs highlights with the packet list.
EVENTS & PACKETS
Figure 1.4 The decode underneath. Detected events are keyed to packet numbers, and every packet is timestamped from the first SYN, tagged by direction, and shown with its sequence and ack state.
