With traffic telemetry, engineers can gain real-time visibility into traffic patterns, correlate events, and make predictions of future traffic patterns. This can be done through a variety of techniques, such as using network taps, port mirroring, or software probes. They can provide detailed information on traffic patterns and usage.
