Thanks for reaching out, Daniel. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
Thanks — I’ll help you monitor participant connection quality, packet loss, and a published microphone track’s bitrate. Brief answer • Subscribe to Room connection-quality events to get per-participant quality updates. • Use per-track telemetry / getStats to read packet loss and bitrate for a published microphone track (or the track as received by a subscriber). • If you need continuous polling, call the stats API on a regular interval and/or listen to connection-quality events for push updates. What to use • RoomEvent.ConnectionQualityChanged — receives updates when a participant’s overall connection quality changes (Poor/Good/Excellent). • Track-level stats / telemetry — exposes packet loss, bitrate, and other metrics for published and subscribed tracks. How to implement (high level) 1. Listen for connection quality changes: ◦ Register a handler for the room’s connection-quality event to get live per-participant quality updates. 1. Inspect track stats: ◦ When you have the participant’s microphone track (published or subscribed), call the SDK’s track stats/telemetry method (or the getStats equivalent). ◦ Read fields such as packet loss rate and current bitrate from the returned stats object. 1. Polling vs events: ◦ For real-time visibility, combine event listeners (ConnectionQualityChanged) with periodic calls to the track stats API (e.g., every 1–5s) if you want a continuous numeric stream. 1. UI/alerts: ◦ Emit or display packet-loss thresholds and bitrate drops based on your tolerance (e.g., packet loss > X% or bitrate below Y kbps). If you’d like, tell me: • Which client SDK are you using (Web, iOS, Android, or server)? • Do you want code samples for event listeners or periodic getStats polling? I’ll provide an exact code snippet once you confirm the SDK. Sources: Announcing LiveKit Cloud | LiveKit, with interactive elements
