What Metrics Are Essential for Real-Time Monitoring of Network Latency and Jitter?

Essential metrics include round-trip time (RTT) to exchanges, which measures latency for order submission. Jitter is monitored by calculating the standard deviation of RTT over short intervals.

Packet loss rate is also critical, as is the time spent in the network interface card (NIC) queue. These metrics must be tracked with microsecond precision and visualized on a real-time dashboard to detect performance degradation immediately.
