Guide identifies six key getStats metrics for effective WebRTC troubleshooting

An analysis of WebRTC's getStats() function argues that only six specific metrics are truly useful for diagnosing connection issues out of the hundreds available. The critical metrics include the selected candidate pair to identify the media path, inbound counters to confirm media arrival, and the outbound quality limitation reason to explain encoder behavior. The author warns that a common error is misidentifying the active candidate pair, which can falsely indicate a direct or relayed connection. Properly joining candidate type data and calculating bitrates from byte deltas are also highlighted as essential for accurate interpretation.
